Detailed Implementation

[0023] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0024] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0025] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0026] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0027] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0028] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element. Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0029] The terminology used herein is for the purpose of describing various examples only and is not intended to limit the examples. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms “comprising,” “including,” and “having” enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0030] Variations in the shapes shown in the accompanying drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the accompanying drawings, but include changes in shape that may occur during manufacturing.

Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0032] This utility model provides a driver controller testing device, such as... Figures 1 to 4 As shown, the driver test device includes a first servo motor 1, a second servo motor 2, a pulley transmission mechanism 3, and a linkage transmission mechanism 4.

[0033] In the following description, reference will be made to Figures 1 to 4 The specific structure of the aforementioned components of the controller testing device and their connection relationships are described in detail.

[0034] like Figures 1 to 4 As shown, in this embodiment, the controller may include a key mechanism 6 and a handle mechanism 7. A first servo motor 1 is connected to a pulley transmission mechanism 3, which is also connected to the key mechanism 6 of the controller. This allows the first servo motor 1 to indirectly drive the key mechanism 6 to rotate, simulating a human hand turning a key, thereby enabling testing of the structural reliability of the key mechanism 6 and the lifespan of its internal components. A second servo motor 2 is connected to a linkage transmission mechanism 4, which is also connected to the handle mechanism 7 of the controller. This allows the second servo motor 2 to drive the handle mechanism 7 to reciprocate, simulating a human hand operating a handle, thereby enabling testing of the structural reliability of the handle mechanism 7 and the lifespan of its internal components.

[0035] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the controller testing device may further include a housing 5. The first servo motor 1, the pulley transmission mechanism 3, the second servo motor 2, and the linkage transmission mechanism 4 can all be mounted on the housing 5 for testing. Preferably, the housing 5 can be a cuboid housing. The housing 5 may include multiple sides and panels disposed on the multiple sides. More preferably, the key mechanism 6 and the handle mechanism 7 can be detachably mounted to the upper panel 51 of the housing 5 using bolts.

[0036] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the pulley transmission mechanism 3 may include a first pulley 31, a second pulley 32, and a synchronous belt 33. The first pulley 31 and the second pulley 32 are mounted on the top of the upper panel 51 via a connecting shaft and bearings, and are connected by the synchronous belt 33. A first servo motor 1 is mounted on the bottom of the upper panel 51 via a bracket, which is bolted to the upper panel 51. The first servo motor 1 is connected to the first pulley 31 via a reducer, and the key mechanism 6 is connected to the second pulley 32 via a connecting shaft. The first servo motor 1 can rotate alternately in both directions at a preset angle and speed, thereby driving the first pulley 31 and the second pulley 32 to rotate reciprocally. This allows the second pulley 32 to simulate a human hand turning a key, testing the structural reliability and service life of the key mechanism 6.

[0037] Furthermore, preferably, such as Figures 1 to 3As shown, in this embodiment, the key mechanism 6 may include a mechanism body 61 and a rotary switch 62. The mechanism body 61 can be mounted on the upper panel 51 via a connecting plate, and the mechanism body 61 extends vertically through the upper panel 51. A second pulley 32 can be mounted on its top, and the second pulley 32 is connected to the mechanism body 61 via a connecting shaft. The rotary switch 62 can be located at the lower part of the upper panel 51. The rotary switch 62 is connected to the bottom of the mechanism body 61. When the second pulley 32 rotates and drives the mechanism body 61 to rotate, the rotary switch 62 will rotate synchronously with the second pulley 32 (i.e., the second pulley 32 can indirectly drive the rotary switch 62 to rotate), thereby allowing detection of whether the rotary switch 62 is working properly and its service life.

[0038] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the linkage transmission mechanism 4 may include a rotating disk 41, a connecting rod 42, and a handle sleeve 43. Specifically, the upper panel 51 may have a strip-shaped slot, and the rotating disk 41 may be disposed within the slot. The rotating disk 41 passes through the slot and is mounted on the upper panel 51. The second servo motor 2 may be mounted on the top of the upper panel 51 via a bracket. The second servo motor 2 may be connected to the rotating disk 41 via a reducer, and the second servo motor 2 may rotate alternately in both directions at a preset angle and speed, thereby driving the rotating disk 41 to reciprocate alternately at a fixed angle and speed. A pin may be provided on the top surface of the rotating disk 41, and the first end of the connecting rod 42 may be hinged to the rotating disk 41 via the pin. The second end of the connecting rod 42 may be hinged to the top of the handle sleeve 43. The handle sleeve 43 may include two plates arranged opposite each other, and the top of the handle mechanism 7 may be clamped and fixed between the two plates, so that the linkage transmission mechanism 4 can drive the handle mechanism 7 to reciprocate, thereby simulating human hand operation of a handle.

[0039] Preferred, such as Figures 1 to 4As shown, in this embodiment, the handle mechanism 7 may include a handle rod 71, a guard plate 72, a handle base 73, and a potentiometer 74. The guard plate 72 can be mounted on the top of the upper panel 51. Two guard plates 72 can be arranged facing each other and spaced apart. The handle base 73 is rotatably mounted between the two guard plates 72 (the handle base 73 and the guard plates 72 can be connected via a pivot). The handle base 73 can be vertically inserted through the upper panel 51, and the handle rod 71 can be located on top of the handle base 73. The top of the handle rod 71 can engage with the handle sleeve 43 (which can be further secured by a set screw), allowing the handle base 73 to be driven by the linkage transmission mechanism 4, thus causing it to rotate. A gear structure (which may not be a complete gear) can be fixed to the bottom of the handle base 73, allowing the potentiometer 74 to be connected to the bottom of the handle base 73 via gear transmission. When the handle base 73 rotates, the potentiometer 74 can rotate synchronously with the handle base 73, thereby allowing detection of whether the potentiometer 74 is functioning properly and its lifespan.

[0040] Preferably, in this embodiment, the controller testing device may further include a controller, which may be a PLC. Specifically, the controller is installed inside the housing 5. The rotary switch 62 and the potentiometer 74 can be connected to the controller via wires to output signals to the controller, thereby recording the number of rotations of the rotary switch 62 and the potentiometer 74.

[0041] Furthermore, preferably, such as Figure 1 As shown, in this embodiment, the housing 5 further includes a side panel 52, which may be perpendicular to the top panel 51. A first counter 521 and a second counter 522 may be spaced apart on the side panel 52. The first counter 521 and the second counter 522 may be connected to a controller via wires. The first counter 521 may be used to display the number of rotations of the 10,000-turn switch 62, and the second counter 522 may be used to display the number of rotations of the potentiometer 74, for easy observation by the operator. Additionally, multiple electronic control buttons 53 may be provided on the side panel 52, which may be used to control the start and stop of the first servo motor 1 and the second servo motor 2.

[0042] Preferred, such as Figures 1 to 4As shown, in this embodiment, the top plate 51 can be provided with a first detection station 510 and a first test station 511. In this case, the number of key mechanisms 6 can be multiple. Multiple key mechanisms 6 are detachably installed on the first detection station 510 and the first test station 511. The key mechanism 6 located in the first detection station 510 can be connected to the pulley drive mechanism 3 for detection. After the key mechanism 6 located in the first detection station 510 completes its detection, the operator can remove it and move the key mechanism 6 located in the first test station 511 to the first detection station 510 for detection. Preferably, as... Figure 2 As shown, the upper panel 51 can be configured with a first detection station 510 and a first test station 511.

[0043] Preferred, such as Figures 1 to 4 As shown, in this embodiment, a second detection station 512 and a second test station 513 can be provided on the top plate 51. In this case, the number of handle mechanisms 7 can be multiple. Multiple handle mechanisms 7 are detachably installed on the second detection station 512 and the second test station 513. The handle mechanism 7 located in the second detection station 512 can be connected to the linkage transmission mechanism 4 for detection. After the handle mechanism 7 located in the second detection station 512 completes the detection, the operator can remove it and move the handle mechanism 7 located in the second test station 513 to the second detection station 512 for detection. Preferably, as... Figure 2 As shown, the upper panel 51 can be equipped with one second detection station 512 and two second test stations 513.

[0044] During use, pressing button 53 on side panel 52 causes the first servo motor 1 to rotate alternately forward and backward at the designed angle and speed. The rotational torque is transmitted to the key mechanism 6 of the controller via pulley transmission mechanism 3, and then to the rotary switch 62 via connecting shaft, causing the rotary switch 62 to rotate alternately forward and backward. The rotary switch 62 can output a signal to the controller and record the number of actions, as well as feed back to the first counter 521 on the front panel to display the cumulative number of movements, thereby testing the structural reliability of the key mechanism 6 and the service life of the rotary switch 62. Similarly, pressing button 53 on side panel 52 causes the second servo motor 2 to rotate alternately forward and backward at the designed angle and speed, driving the rotating disk 41 to reciprocate. The rotating disk 41 drives the handle sleeve 43 to reciprocate back and forth via connecting rod 42, simulating human hand operation of the handle. The handle mechanism 7, driven by the connecting rod transmission mechanism 4, drives the potentiometer 74 to rotate alternately forward and backward. The potentiometer 74 can output a signal to the controller and record the number of times the action is performed, as well as feed back to the second counter 522 on the front panel to display the cumulative number of movements, thereby enabling the testing of the structural reliability of the handle mechanism 7 and the service life of the potentiometer 74.
