[0038] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the following will further describe the present application. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some of the embodiments of the present application, not all the embodiments.

[0040] At present, a cup holder is arranged in an automobile, the cup holder is an important storage structure in the automobile, and is used for placing a water cup, a beverage bottle and the like of a user of the automobile. A cup holder claw is a key component of the cup holder. At present, the cup holder claw is mechanical or soft rubber type. The performance of the product cannot be accurately measured according to the size and related technical requirements to reach a normal service life.

[0041] Meanwhile, the durability and stability of the cup holder claw are directly related to the satisfaction of the user. In order to ensure the durability and reliability of the cup holder claw, before the cup holder is put into the market, an insertion and pulling-out durability test is carried out by simulating different environmental conditions, and all components, linking parts and claws are required not to have failure phenomena such as whitening, peeling and slag dropping.

[0042] In order to solve the above technical problems, please refer to Figure 1 and Figure 2 , Figure 1 a schematic view of a cup holder claw durability test device 100 provided by some embodiments of the present application, Figure 2 a side view of the cup holder claw durability test device 100 shown in Figure 1 . The present application provides a cup holder claw durability test device 100, which can include a workbench 110, a telescopic assembly, a guide rail module, a conversion assembly, a water cup simulator 150 and a clamp 160.

[0043] The workbench 110 is formed as a frame structure, and is a base of the whole device 100. The workbench 110 can be assembled by a plurality of metal rods. The workbench 110 is provided with a workbench 111 on a side away from the ground. The upper surface of the workbench 111 is formed as a work surface 1111.

[0044] The telescopic assembly is arranged on the work surface 1111. The movable end 121 of the telescopic assembly can make reciprocating linear motion in a first direction (for example, the left-right direction shown in Figure 1 . The first direction is parallel to the work surface 1111.

[0045] The guide rail module is arranged on the work surface 1111 and located on a side of the movable end 121 of the telescopic assembly. The guide rail module includes a guide rail 131 and a sliding block 132. The guide rail 131 extends in a direction perpendicular to the work surface 1111 (for example, the up-down direction shown in Figure 1 . The sliding block 132 is sleeved on the guide rail 131 and can slide along the extension direction of the guide rail 131.

[0046] The conversion assembly is connected between the movable end 121 and the sliding block 132. The conversion assembly can convert the linear motion of the movable end 121 in the first direction into the sliding of the sliding block 132 along the extension direction of the guide rail 131.

[0047] Specifically, the conversion assembly may include a conversion bracket 141, a rotating block 142, a first connecting rod 143, and a second connecting rod 144. The conversion bracket 141 is disposed on the working surface 1111 and located between the guide rail module and the telescopic assembly. The conversion bracket 141 includes a crossbar 1411, which is spaced apart from the working surface 1111. The extension direction of the crossbar 1411 (e.g., Figure 1 The front-back direction shown is parallel to the working surface 1111 and perpendicular to the first direction; the rotating block 142 is rotatably sleeved on the crossbar 1411; the first connecting rod 143 is movably inserted through the movable end 121 and is rotatably connected to the rotating block 142; one end of the second connecting rod 144 is connected to the rotating block 142, and the other end is rotatably connected to the slider 132.

[0048] The rotating block 142 and the crossbar 1411 are connected by a bearing to reduce friction.

[0049] A cup simulator 150 is mounted on a slider 132, and a clamp 160 is used to hold a cup holder 200. The clamp 160 is mounted on a worktable 110. The cup simulator 150 and the clamp 160 are positioned opposite each other in the extension direction of the guide rail 131.

[0050] Therefore, the conversion component is set to convert the linear movement of the telescopic component in the first direction into the movement of the slider 132 in the extension direction of the guide rail 131. Specifically, the movable end 121 of the telescopic component moves linearly in the first direction, applying a pulling or pushing force to the first connecting rod 143, so that the first connecting rod 143 drives the rotating block 142 to rotate. The rotation of the rotating block 142 drives the second connecting rod 144 to move. The movement of the second connecting rod 144 drives the slider 132 to slide along the extension direction of the guide rail 131.

[0051] The sliding of slider 132 in the extension direction of guide rail 131 causes cup simulator 150 to move back and forth along the extension direction of guide rail 131, thereby simulating the insertion and removal of cup holder 200 in clamp 160 and thus achieving durability testing of cup holder claw.

[0052] Specifically, the insertion and withdrawal durability tests should be conducted according to the following requirements: Stage 1: 7000 cycles (23±2℃); Stage 2: 1000 cycles (85±2℃); Stage 3: 1000 cycles (-30±2℃); Stage 4: 1000 cycles (40±2℃, relative humidity 95%). Each cycle constitutes one lifetime, and a total of two cycles must be completed. Visual and functional checks should be performed and recorded after each stage.

Figure 1 and Figure 2 and refer to Figure 3 , Figure 3 forFigure 1 The schematic diagram of the water cup simulator 150 shown in the middle; the water cup simulator 150 is formed in a cylindrical shape and is connected to the slider 132 through a bolt, the water cup simulator 150 is coaxially arranged with the clamp 160, when used by the worker, the water cup simulator 150 has good coaxiality with the cup holder 200 and does not shake or deform, thereby improving the test accuracy of the cup holder 200.

[0054] It can be understood that please continue to refer to Figure 1 and Figure 2 The device 100 can also include a direct current power supply 170 and a time relay 180, the time relay 180 is electrically connected with the direct current power supply 170 and the telescopic assembly respectively, thereby, by setting the time relay 180, the time of inserting the water cup simulator 150 into the container, fixing the container and removing the container is controlled, the frequency of the pawl durability test per minute is not more than 10 times, and it is ensured that the pawl durability test frequency meets the standard requirements.

[0055] In order to realize that each time the pawl durability test can be performed on multiple cup holders 200 at the same time, in some embodiments of the present application, the device 100 includes multiple water cup simulators 150 and multiple clamps 160, the multiple water cup simulators 150 correspond to the multiple clamps 160 one by one, specifically, the number of water cup simulators 150 can be 3, and the number of clamps 160 is also 3.

[0056] Specifically, the device 100 can also include an expansion connecting plate, the expansion connecting plate 190 can include a main plate and multiple sub-plates, the multiple sub-plates correspond to the multiple water cup simulators 150 one by one, the multiple sub-plates are arranged on the main plate, and the main plate is connected with the slider 132.

[0057] In some embodiments of the present application, please continue to refer to Figure 1 and Figure 2 The telescopic assembly can include a telescopic cylinder 122 and an extension rod, the extension rod extends in the first direction, one end of the extension rod is connected with the output end of the telescopic cylinder 122, and the other end is formed as a movable end 121. Thus, by setting the telescopic cylinder 122 and the extension rod, the action distance of the telescopic cylinder 122 can be extended.

[0058] In the specific experimental process, the device as a whole is located in the laboratory, the laboratory is used to simulate different environments of the plug-in and plug-out experiment, the extension rod is arranged in the side wall of the laboratory, the telescopic cylinder 122, the direct current power supply 170 and the time relay 180 are located outside the laboratory, thereby, on the one hand, it is convenient for the worker to operate the electrical elements such as the telescopic cylinder 122, the direct current power supply 170 and the time relay 180, on the other hand, it can avoid the failure of the time relay 180 and the telescopic cylinder 122 under extreme environmental conditions.

[0059] Specifically, the device 100 can further include a tool support 124 arranged on the working surface 1111 and used to fix the cylinder of the telescopic cylinder 122.

[0060] Further, the device 100 can further include a support support 125 arranged between the movable end 121 and the tool support 124, the support support 125 is arranged on the workbench 110, and the extension rod is arranged on the support support 125. It can be understood that, since the length of the extension rod is relatively long, the support support 125 is arranged on the basis of the work support, which can ensure the stability of the extension rod during movement and avoid the extension rod from being tilted due to the influence of gravity.

[0061] In some embodiments of the present application, the extension rod can include: a first extension rod 1231, a first connecting plate 1233, a plurality of second extension rods 1232, one end of the first extension rod 1231 is connected with the output end, the other end is connected with the first connecting plate 1233, one end of the second extension rod 1232 is arranged on the side surface of the first connecting plate 1233 away from the first extension rod 1231, the other end extends towards the guide rail module and is connected with the movable end 121, the plurality of second extension rods 1232 are arranged in the second direction, the second direction is parallel to the working surface 1111 and perpendicular to the first direction; wherein, the plurality of second extension rods 1232 are arranged on the support support 125.

[0062] Specifically, the number of second extension rods 1232 is two, the support support 125 is provided with a avoiding hole matched with the second extension rod 1232, and the second extension rod 1232 is arranged in the avoiding hole.

[0063] Therefore, by arranging the plurality of second extension rods 1232 arranged in the second direction, the rotation of the extension rod in the circumferential direction can be avoided, and the stability of the extension rod during movement is further ensured.

[0064] Further, the extension rod can further include a second connecting plate 1234 arranged between the plurality of second extension rods 1232 and the movable end 121. It can be understood that, since the number of second extension rods 1232 is multiple, the second connecting plate 1234 is arranged, so as to connect the movable end 121 and the plurality of second extension rods 1232 at the same time.

[0065] Specifically, in the second direction, the movable end 121 is located at the middle position of the second connecting plate 1234.

[0066] In some embodiments of the present application, please refer to Figure 4 , Figure 4 To Figure 1A schematic view of the second connecting rod 144 shown in FIG. 1. The second connecting rod 144 can include a first sub-rod 1441 and a second sub-rod 1442, one end of the first sub-rod 1441 is connected with the rotating block 142, the other end is rotatably connected with one end of the second sub-rod 1442, the other end of the second sub-rod 1442 is rotatably connected with the sliding block 132. Specifically, the sliding block 132 is provided with a connecting block 1321, and the second sub-rod 1442 is rotatably connected with the connecting block 1321.

[0067] Therefore, by setting the second connecting rod 144 as the first sub-rod 1441 and the second sub-rod 1442, the interference between the second connecting rod 144 and the sliding block 132 and the rotating block 142 during the rotation of the rotating block 142 can be reduced, thereby ensuring the stability of the second connecting rod 144 during operation.

[0068] In some embodiments of the present application, please refer to Figure 5 , Figure 5 for Figure 1 A schematic view of the first connecting rod 143 shown in FIG. 1. The movable end 121 is provided with a movable hole 1211, and the first connecting rod 143 is arranged in the movable hole 1211. The radial dimension of the end of the first connecting rod 143 away from the rotating block 142 is greater than the radial dimension of the movable hole 1211.

[0069] It should be noted that during the process of driving the first connecting rod 143 by the movable end 121, the first connecting rod 143 will move in the movable hole 1211. By setting the radial dimension of the end of the first connecting rod 143 away from the movable block to be greater than the radial dimension of the movable hole 1211, the situation that the first connecting rod 143 is separated from the movable end 121 during movement can be avoided.
