[0062] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description herein. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0063] The present application uses specific words to describe the embodiments of the present application. For example, "one embodiment", "other embodiments", and / or "some embodiments" refer to a certain feature, structure or characteristic related to at least one embodiment of the present application. Therefore, it should be emphasized and noted that "one embodiment" or "other embodiments" or "some embodiments" mentioned twice or multiple times in different positions in this specification do not necessarily refer to the same embodiment. In addition, some features, structures or characteristics in one or more embodiments of the present application can be appropriately combined.

[0064] It should be noted that in order to simplify the description disclosed in this application and thus help understand one or more embodiments, in the above description of the embodiments of this application, multiple features are sometimes merged into one embodiment, figure or description thereof. However, this disclosure method does not mean that the features required by the object of this application are more than the features mentioned in the claims. In fact, the features of the embodiments are less than all the features of the single embodiment disclosed above.

[0065] Reference Figure 1 , Figure 1 FIG. 1 shows a perspective view of a multi-electric test bench system 10 according to an embodiment of the present invention. Figure 1 As shown, the multi-electric test bench system (also referred to as a traction system) 10 includes a device 20 and three electric test benches 40, wherein the device 20 includes a frame 21, the frame 21 extends a height in the vertical direction V, and the three electric test benches 40 are installed at different heights in the frame 21. In some embodiments, the three electric test benches 40 can be different electric test platforms for electric testing of different types of wiring harnesses. In other embodiments, one or more of the three electric test benches 40 can be the same electric test platform for electric testing of the same type of wiring harness. In addition, although Figure 1 21 shows that three electrical test stations 40 are installed in the device 20, but it should be understood that those skilled in the art can install other numbers of electrical test stations 40 in the frame 21 as needed, for example, 1 electrical test station, 2 electrical test stations, or more than three electrical test stations. Multiple electrical test stations 40 are installed in the same frame 21, which allows multiple electrical test stations 40 to share one electrical test system, thereby saving the cost of testing multiple wiring harnesses. In other embodiments, the system 10 can be used to move other objects, not just limited to moving the electrical test station 40.

[0066] like Figure 1 As shown, the device 20 may further include a guide rail portion 23 and a stopper 25, wherein the stopper 25 may be mounted to the guide rail portion 23 and movable relative to the guide rail portion 23. When the electrical test bench 40 is mounted in the frame 21, the electrical test bench 40 is fixed to the stopper 25, as shown in FIG. Figure 2 Shown in detail. Figure 2 FIG. 1 is a partial enlarged schematic diagram showing the assembly relationship between the electric test bench 40, the stopper 25 and the guide rail portion 23 in the multi-electric test bench system 10 according to an embodiment of the present invention. Figure 2 As shown, the stopping device 25 may include a fixing plate 251 , a slider 253 and a brake 255 , wherein the slider 253 and the brake 255 are mounted on the fixing plate 251 .

[0067] In some embodiments, Figure 2 As shown, the guide rail portion 23 has a wall 231 and has a T-shaped cross section perpendicular to its extension direction. When the stopper 25 is mounted to the guide rail portion 23, the slider 251 can be located on one side of the wall 231 of the guide rail portion 23. The brake 253 can have two brake pads ( Figure 2Only one brake pad is shown in the figure, one of which can be located on the side of the guide rail portion 23 where the slider 251 is located, and the other brake pad can be located on the other side of the guide rail portion 23. When the brake 253 is in a deactivated state (e.g., a released state), the two brake pads are not in contact with the wall 231 of the guide rail portion 23 and can move along the vertical direction V with the stopper 25 relative to the guide rail portion 23. When the brake 253 is in an activated state (e.g., a locked state), the two brake pads move toward the wall 231 to contact the wall 231 of the guide rail portion 23, thereby preventing the entire stopper 25 from moving relative to the guide rail portion 23 along the vertical direction V.

[0068] In other embodiments, the guide rail portion 23 may have a groove and have a U-shaped cross-section perpendicular to its extension direction. When the stopper 25 is mounted to the guide rail portion 23, the slider 251 may be located in the groove of the guide rail portion 23. The brake 253 may have two brake pads, both of which are located in the groove. When the brake 253 is in a deactivated state (e.g., a released state), the two brake pads do not contact the two side walls of the groove of the guide rail portion 23 and can move along the vertical direction V with the stopper 25 relative to the guide rail portion 23. When the brake 253 is in an activated state (e.g., a locked state), the two brake pads move back toward the two side walls respectively to contact the two side walls of the guide rail portion 23 respectively, thereby preventing the entire stopper 25 from moving along the vertical direction V relative to the guide rail portion 23.

[0069] See also Figure 2 When the electrical testing platform 40 is installed in the frame 21, the electrical testing platform 40 can be fixed to the fixing plate 251 of the stopping device 25, and can be moved and positioned relative to the guide rail portion 23 through the stopping device 25, thereby achieving movement and positioning in the vertical direction V in the frame 21.

[0070] Return to reference Figure 1 ,exist Figure 1 In the embodiment, the three electric test stations 40 installed in the frame 21 of the device 20 have substantially the same shape and size, the number of the guide rails 23 is four, the four guide rails 23 are respectively vertically arranged near the four corners of the inner side of the frame 21, and the distance between the four guide rails 23 is set to match the size of the three electric test stations 40 installed in the frame 21. In some embodiments, multiple electric test stations 40 can share the guide rail 23, such as Figure 1 As shown. The number of shared rail portions 23 can be set to other numbers, such as 1, 2, 3 or more than four. The positions of these shared rail portions 23 can be reasonably set based on the number of rail portions 23 and the shape and size of the electrical test bench 40. For example, two of the four shared rail portions 23 can be symmetrically arranged on the left side of the electrical test bench 40 and the other two can be symmetrically arranged on the right side of the electrical test bench 40 (such as Figure 1 ), or two of the four shared rail portions 23 may be symmetrically disposed at the front side of the electrical testing station 40 and the other two may be symmetrically disposed at the rear side of the electrical testing station 40. In some embodiments, all shared rail portions 23 (e.g., one or more shared rail portions 23) may be disposed side by side at one side of the electrical testing station 40, such as the rear side. In embodiments where all shared rail portions 23 are disposed at the rear side of the electrical testing station 40, the shapes and / or sizes of the plurality of electrical testing stations 40 may be different. In other embodiments, dedicated rail portions 23 may be provided for one or more electrical testing stations 40 of different shapes and / or sizes, and the number of dedicated rail portions 23 may be the same or different for each electrical testing station 40.

[0071] Reference Figure 1 For each electrical test station 40, the device 20 may include four stoppers 25 corresponding to the four guide rails 23, respectively. Figure 1 In the embodiment shown, which includes three electrical test stations 40 and four guide rail portions 23 for common use by the three electrical test stations 40, the apparatus 20 may include 12 stop devices 25. The number of stop devices 25 may be adjusted accordingly based on the number of electrical test stations 40 and the number of guide rail portions 23 to be used by each electrical test station 40. The number of stop devices 23 may be set to be equal to the sum of the number of guide rail portions 23 to be used by each electrical test station 40.

[0072] See also Figure 1 The device 20 may also include a stop drive mechanism and a traction mechanism, wherein the traction mechanism may include fixed pulleys 261-262, fixed pulleys 263A-263D, a movable pulley 264, a balance bar 265 and a plurality of traction lines ( Figure 1 ). The stop drive mechanism can implement driving and / or stopping as needed to move and / or fix the electric test bench 40 in the vertical direction V. The stop drive mechanism can be implemented by a combination of one device or multiple devices. In some embodiments, the stop drive mechanism may include one or both of the drive device 24 and the above-mentioned stop device 25. In some other embodiments, the drive device 24 may include a winch or other electromechanical device capable of applying a driving force. It should be understood that the device 20 may not include the drive device 24, for example, the operator may apply a driving force to the traction mechanism to drive the electric test bench 40 to move in the vertical direction V in the frame 21. In this article, the term "fixed pulley" means that the pulley is fixed relative to the frame 21 or other reference objects, and the term "movable pulley" means that the pulley is movable relative to the frame 21 or other reference objects.

[0073] The following reference Figure 3 The following describes in detail how the driving device 24 drives the electric test bench 40 to move and position along the vertical direction V in the frame 21 via the traction mechanism. Figure 3 FIG. 1 is a schematic diagram showing the assembly relationship between the traction mechanism, the electric test bench 40 and the drive device 24 in the multi-electric test bench system 10 according to an embodiment of the present invention. For the sake of clarity, Figure 3 Only the traction mechanism and the driving device 24 for one electric test station 40 in the device 20 are shown. The other electric test stations 40 may have the same or different traction mechanisms and driving devices 24 as the one electric test station 40.

[0074] like Figure 3 As shown, the traction mechanism may include a traction line 266, one end of which is connected to the driving device 24, and the traction line 266 passes through the fixed pulley 261, the fixed pulley 262 and the movable pulley 264 in sequence in the middle, and the other end is connected to the bottom plate 211 of the frame 21. The driving device 24 and the fixed pulley 261 may be approximately in the same horizontal position, the fixed pulley 261 and the fixed pulley 262 may be approximately in the same vertical position, and the movable pulley 264 may be located between the fixed pulley 261 and the fixed pulley 262. In this embodiment, the fixed pulley 261 is used to change the direction of the traction line 266, forming a redirection mechanism. The traction line 266, the fixed pulley 262 and the movable pulley 264 form a labor-saving component, which allows a smaller driving force to be applied, and can play a labor-saving role.

[0075] like Figure 3 As shown, the electric test bench 40 may have four traction parts 41A-41D arranged symmetrically relative to its center of gravity. Correspondingly, the traction mechanism may have four traction wires 267A-267D, one end of the traction wires 267A-267D may be connected to the corresponding traction parts 41A-41D respectively, the middle may pass through the fixed pulleys 263A-263D located directly above the traction parts 41A-41D respectively, and the other end may be connected to the balance pole 265. For example, Figure 3 As shown, one end of the traction line 267A can be connected to the traction part 41A, and the fixed pulleys 263A and 263D are sequentially bypassed in the middle, and the other end is connected to the balance bar 265; one end of the traction line 267B can be connected to the traction part 41B, and the fixed pulleys 263B and 263C are sequentially bypassed in the middle, and the other end is connected to the balance bar 265; one end of the traction line 267C can be connected to the traction part 41C, and the fixed pulley 263C is bypassed in the middle, and the other end is connected to the balance bar 265; one end of the traction line 267D can be connected to the traction part 41D, and the fixed pulley 263D is bypassed in the middle, and the other end is connected to the balance bar 265. Among them, the fixed pulleys 263A-263D can be located directly above the traction parts 41A-41D of the electric test bench 40, respectively, and the balance bar 265 can be located below the fixed pulleys 263C and 263D, and is movably installed between the two guide rail parts 23 and fixed to the movable pulley 264.

[0076] In some embodiments, when the winch used as the driving device 24 rotates to tighten the traction line 266, the traction line 266 can apply a downward force F1 to the movable pulley 266 and even the balance bar 265 fixed to the movable pulley 266. When the force F1 is greater than the weight F2 of the electric test platform 40 (for ease of understanding, the friction between the traction line and the pulley is ignored here), the movable pulley 264 together with the balance bar 265 can move downward together. When the balance bar 265 moves downward, the traction lines 267A-267D connected to the balance bar 265 at one end can pull the electric test platform 40 upward through the other end connected to the traction part, so that the electric test platform 40 moves upward in the vertical direction V in the frame 21. The present invention can allow the use of a driving device 24 with less power to drive the electric test platform 40 to move in the vertical direction V by using a labor-saving component (for example, including the traction line 266, the fixed pulley 262 and the movable pulley 264). In addition, by using the balancing pole 265 , the stability of the electric test stand 40 moving within the frame 21 can be increased.

[0077] When the winch rotates to release the traction line 266, the traction line 266 applies a downward force F1 to the movable pulley 264 and even the balance bar 265 fixed to the movable pulley 264. When F1 is less than the gravity F2 of the electrical test platform 40, the electrical test platform 40 can move downward in the vertical direction V within the frame 21 under the action of its gravity, and at the same time, the balance bar 265 together with the movable pulley 264 can move upward accordingly.

[0078] When the winch stops rotating, the downward force F1 exerted by the traction line 266 on the movable pulley 264 and the balance bar 265 fixed to the movable pulley 264 can reach a balance with the gravity F2 of the electrical test platform 40. At this time, the movable pulley 264 and the balance bar 265 can remain stationary, and the electrical test platform 40 can also remain stationary accordingly, so as to be fixed at a certain height in the frame 21.

[0079] In the above embodiment, the traction mechanism is described as including a fixed pulley 261 as a redirection mechanism, wherein the fixed pulley 261 is approximately at the same horizontal position as the drive device 24 and is approximately at the same vertical position as the fixed pulley 262 (for example, the fixed pulley 261 is located directly above or directly below the fixed pulley 262). In other embodiments, the traction mechanism may include other redirection mechanisms as a replacement or supplement to the fixed pulley 261, wherein the other redirection mechanisms are positioned so that the traction line 266 will be applied with a horizontal driving force, for example, the other redirection mechanisms may be located above the fixed pulley 262 and approximately at the same horizontal position as the drive device 24. In other embodiments, the traction mechanism may not include a redirection mechanism (such as a fixed pulley 261), and the traction line 266 may extend from the drive device 24 and directly bypass the fixed pulley 262 and the movable pulley 264 in sequence, wherein the fixed pulley 262 and the drive device 24 may be approximately at the same vertical position or approximately at the same horizontal position.

[0080] Furthermore, the traction mechanism may not include the labor-saving components (e.g., the fixed pulley 262, the movable pulley 264, and the traction line 266) and the balance bar 265, but may only include the traction lines 267A-267D and the fixed pulleys 263A-263D. One end of the traction lines 267A-267D may be respectively connected to the traction parts 41A-41D of the electric test platform 40, and the fixed pulleys above the corresponding traction parts may be passed around in the middle, and the other end of the traction lines 267A-267D may be connected to the driving device 24. For example, one end of the traction line 267A can be connected to the traction part 41A, bypass the fixed pulley 263A in the middle (and additionally, can also bypass the fixed pulley 263D), and the other end is connected to the drive device 24; one end of the traction line 267B can be connected to the traction part 41B, bypass the fixed pulley 263B in the middle (and additionally, can also bypass the fixed pulley 263C), and the other end is connected to the drive device 24; one end of the traction line 267C can be connected to the traction part 41C, bypass the fixed pulley 263C in the middle, and the other end is connected to the drive device 24; one end of the traction line 267D can be connected to the traction part 41D, bypass the fixed pulley 263D in the middle, and the other end is connected to the drive device 24.

[0081] Although the aforementioned embodiment depicts the electrical test bench 40 as having four traction parts 41A-41D, the four traction parts 41A-41D are symmetrically arranged relative to the center of gravity of the electrical test bench 40, and accordingly, the traction mechanism may include four traction wires 267A-267D and four fixed pulleys 263A-263D respectively located directly above the traction parts 41A-41D. However, in other embodiments, the electrical test bench 40 may have other numbers of traction parts, for example, one traction part (which may be located at the center of gravity of the electrical test bench 40), two traction parts, three traction parts, or more than four traction parts. When the number of traction parts is more than one, the traction parts may be arranged in a balanced manner relative to the center of gravity of the electrical test bench 40 to increase the stability of the electrical test bench 40 moving within the frame 21. Accordingly, the traction mechanism may include the same number of traction lines 267 as the number of traction parts, and the same number of fixed pulleys 263 as the number of traction parts, wherein these fixed pulleys 263 may be positioned so that the resultant force applied to the electrical testing platform 40 is vertically upward, and the point of action of the resultant force is located at the center of gravity of the electrical testing platform 40.

[0082] Return to see Figure 1 The device 20 may further include stoppers 28A and 28B, which may be fixedly mounted to the frame 21 to prevent the electric test bench 40 mounted thereon from falling downward or moving below the stoppers 28A and 28B. Figure 4A and Figure 4B Schematic diagrams showing the blockers 28A and 28B in the multi-electric test bench system 10 according to an embodiment of the present invention in the disabled state and the enabled state, respectively. Figure 4A As shown in FIG. 2 , when the blockers 28A and 28B are in the deactivated state, the electric test bench 40 located above the blockers 28A and 28B can be moved downward to below the blockers 28A and 28B in the frame 21. In addition, when the blockers 28A and 28B are in the deactivated state, the electric test bench 40 located below the blockers 28A and 28B ( Figure 4A 28A and 28B. Figure 4B As shown in FIG. 1 , when the blockers 28A and 28B are in the enabled state, the blocking member 281A on the blocker 28A and the blocking member 281B on the blocker 28B move to the position directly below the electric test platform 40 so as to prevent the electric test platform 40 above the blocker 28 from falling down or moving below the blockers 28A and 28B. In addition, when the blockers 28A and 28B are in the enabled state, the blocking member 281A on the blocker 28A and the blocking member 281B on the blocker 28B can also be used to prevent the electric test platform 40 below the blockers 28A and 28B from falling down or moving below the blockers 28A and 28B. Figure 4B 28A and 28B).

[0083] Additionally, the device 20 may further include a safety light barrier 29 ( Figure 1 (not shown in the figure), the safety light barrier 29 can be set in or near the operating area of ​​the device 20. The operating area may include the physical space where the device 20 is located. When the safety light barrier 29 is in an enabled state, it can detect whether someone enters the operating area of ​​the device 20.

[0084] Additionally, the device 20 may further include a controller 50 . Figure 5 A schematic diagram showing the communicative coupling between the controller 50 and other components in the device 20 according to an embodiment of the present invention.

[0085] like Figure 5 As shown, the controller 50 may be communicatively coupled with the driving device 24. The controller 50 may be configured to: control the driving device 24 to drive so that the electric test bench 40 moves in the frame 21 along the vertical direction V (including moving upward or downward); and control the driving device 24 to stop driving so that the electric test bench 40 is fixed at a certain height in the frame 21.

[0086] The controller 50 may also be communicatively coupled with the stop device 25 (e.g., brake 255), and further configured to: control the stop device 25 to allow or prevent the stop device 25 from moving relative to the guide rail portion 23. For example, the controller 50 may be further configured to: control the brake 255 to be in a deactivated state (e.g., released state) to allow the brake 255 to move relative to the guide rail portion 23, thereby allowing the electric test bench 40 to move in the vertical direction V within the frame 21; or control the brake 255 to be in an activated state (e.g., locked state) to prevent the brake 255 and even the stop device 25 from moving relative to the guide rail portion 23, thereby preventing the electric test bench 40 from moving in the vertical direction V within the frame 21. By using the brake 255 to prevent the electric test bench 40 from moving within the frame 21, the positioning accuracy of the electric test bench 40 in the frame 21 can be improved.

[0087] The controller 50 can also be communicatively coupled with the blockers 28A and 28B, and is further configured to: control the blockers 28A and 28B to be in a disabled state to allow the electric test platform 40 to move through the blockers 28A and 28B; or control the blockers 28A and 28B to be in an enabled state to prevent the electric test platform 40 from moving through the blockers 28A and 28B. By using the blockers 28A and 28B, the electric test platform 40 located above the blockers 28A and 28B can be prevented from accidentally falling, thereby improving the safety of the operators located below the blockers 28A and 28B.

[0088] The controller 50 may also be communicatively coupled with the safety light barrier 29, and further configured to: control the safety light barrier 29 to be in a deactivated state to allow operators to freely enter the operating area of ​​the multi-electrical test platform system 10; or control the safety light barrier 29 to be in an activated state to detect whether a person enters the operating area of ​​the multi-electrical test platform system 10. In some embodiments, the controller 50 may be configured to: control the safety light barrier 29 to be in an activated state during the control of the drive device 24 to drive to move the electric test platform 40; or control the safety light barrier 29 to be in a deactivated state after the electric test platform 40 has been moved to a specified height. The controller 50 may be further configured to: in response to the safety light barrier 29 detecting that a person has entered the operating area of ​​the multi-electrical test platform system 10, issue a visual or audible warning, and / or stop or terminate driving the drive device 24. On the one hand, this can avoid potential dangers to operators due to entering the operating area of ​​the multi-electrical test station system 10 at an inappropriate time (for example, when the electrical test station 40 is moving), and on the other hand, it can also prevent the multi-electrical test station system 10 from being disturbed by the outside world during the movement of the electrical test station 40.

[0089] While the present invention has been described according to the preferred embodiments thereof, it is not intended to be limited thereto but only to the scope set forth in the appended claims.
