Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0032] In the description of the present invention, it should be noted that the term "including" and its variations represent open inclusion, that is, "including but not limited to". The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, in the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] The present invention provides a detection device for detecting the abuse of a water cup holder, referring to Figure 1-Figure 3 As shown, it includes a detection head 10, a first driving mechanism and a second driving mechanism. The detection head 10 includes a first shaft 11 and a pressure head 12; the pressure head 12 is adapted to the inner wall of the cup holder. For example, when the inner wall of the cup holder is set as a cylindrical surface, the pressure head 12 can be set as a cylindrical surface accordingly; when the inner wall of the cup holder is set as a conical surface, the pressure head 12 can be set as a conical surface accordingly; when the inner wall of the cup holder is set as a plane, the pressure head 12 can be set as a plane accordingly, so that the pressure head 12 can better fit the inner wall of the cup holder. The pressure head 12 is connected to the first driving mechanism, and the first driving mechanism is used to drive the pressure head 12 to move in a direction perpendicular to the first shaft 11. The first end of the first shaft 11 is connected to the second driving mechanism, and the second driving mechanism is used to drive the first shaft 11 to move in the extension direction of the first shaft 11; the pressure head 12 is connected to the first shaft 11 through the first driving mechanism.

[0034] During the inspection, the second driving mechanism drives the first shaft 11 to move downward, and the first driving mechanism and the pressure head 12 move downward along with the first shaft 11, so that the pressure head 12 extends into the cup holder. The second driving mechanism drives the pressure head 12 to expand horizontally outward, so that the pressure head 12 fits the inner wall of the cup holder, and then the second driving mechanism continues to drive the pressure head 12 to expand horizontally outward, so that positive pressure can be applied to the inner wall of the cup holder. The force applied is accurate in size and direction and has good consistency, so that the inspection process can be standardized.

[0035] In one embodiment, reference Figure 2 and Figure 3As shown, the first driving mechanism includes a detection disk 21, a driving disk 22, a first driver 23 and a second shaft 24. The detection disk 21 is fixedly arranged at the second end of the first shaft 11, and the driving disk 22 is rotatably sleeved on the first shaft 11; the first end of the second shaft 24 is arranged at the output end of the first driver 23, and the second end of the second shaft 24 is fixedly provided with a first gear 25; the driving disk 22 is fixedly provided with a second gear 221, and the second gear 221 is rotatably sleeved on the first shaft 11 and meshes with the first gear 25. The upper surface of the detection disk 21 is provided with a plurality of limit posts 211 arranged along the circumference thereof, and a push rod 26 is provided between two adjacent limit posts 211, the pressure head 12 is provided at the first end of the push rod 26, and the second end of the push rod 26 is provided with a guide post 261 perpendicular to the push rod 26, and the driving disk 22 is provided with a plurality of first long holes 222 extending along the radial direction thereof, and the guide posts 261 are inserted into the first long holes 222.

[0036] When the first driver 23 is running, it drives the second shaft 24 to rotate, and the second shaft 24 rotates with the first gear 25. The first gear 25 drives the second gear 221 to rotate, and the second gear 221 rotates with the driving disk 22. When the driving disk 22 rotates, it pushes the guide column 261 to move along the first long hole 222, and the push rod 26 moves between the two limit columns 211, and expands the pressure head 12 toward the inner wall of the cup holder, so that the pressure head 12 fits the inner wall of the cup holder.

[0037] Preferably, the second gear 221 can be arranged on the upper surface of the driving disk 22, so as to facilitate the arrangement of the second shaft 24 and the second gear 221, and make the structure of the detection device simpler. The push rod 26 is set as a rectangular rod, and the cross section of the limit column 211 can be set as an oblong, and the rectangular rod can be better limited and guided by the long side of the limit column 211. The pressure head 12 can be set as a plurality of uniformly distributed around the axis of the driving disk 22, for example, it can be set as two, three or four, etc. The push rod 26, the guide column 261, the limit column 211 and the first long hole 222 are set accordingly with the pressure head 12, and can evenly apply force to all directions of the inner side wall of the water cup holder. The driving disk 22 can be set as a disc, and can also be set as a straight disc, a three-leaf disc, a cross disc, etc., to reduce weight. The pressure head 12 and the push rod 26 can be threadedly connected to facilitate the replacement of the pressure head 12.

[0038] In one embodiment, a bearing is provided between the second gear 221 and the first shaft 11, the outer ring of the bearing is fixedly connected to the second gear 221, and the inner ring of the bearing is fixedly connected to the first shaft 11. Specifically, the outer ring of the bearing can be connected to the second gear 221 by interference fit, and the inner ring of the bearing can be connected to the first shaft 11 by interference fit. When the second gear 221 rotates, the first shaft 11 remains stationary. By connecting the second gear 221 and the first shaft 11 by a bearing, the second gear 221 can be kept coaxial with the first shaft 11 to prevent the second gear 221 from contacting the first shaft 11. At the same time, when the first shaft 11 moves up and down, it can move up and down synchronously with the second gear 221, that is, keep the detection disk 21, the driving disk 22 and the push rod 26 moving up and down synchronously, so that the operation process is more stable and efficient.

[0039] The first shaft 11 is fixedly provided with a connecting plate 27, and the first driver 23 is fixedly provided on the connecting plate 27. Specifically, one end of the connecting plate 27 can be welded and fixed to the first shaft 11, or a threaded portion can be provided on the first shaft 11, and a threaded hole matching the threaded portion can be provided at one end of the connecting plate 27, so that the connecting plate 27 is threadedly connected to the first shaft 11, and a second through hole and a third through hole matching each other can be provided on the connecting plate 27 and the first shaft 11, and fixed by a bolt and nut assembly. The first driver 23 can be fixedly provided on the top surface of the connecting plate 27, and a fourth through hole can be provided at the other end of the connecting plate 27, and the second shaft 24 extends out of the fourth through hole. In this way, when the first shaft 11 moves up and down, it can bring the first driver 23, the second shaft 24, the first gear 25 and the second gear 221 to move up and down synchronously, so that the first gear 25 and the second gear 221 remain meshed.

[0040] In one embodiment, Figure 1 As shown, the second drive mechanism includes a screw transmission mechanism, which includes a second driver 31, a matching screw 32 and a slider 33. The extension direction of the screw 32 is consistent with the extension direction of the first shaft 11. The second driver 31 is used to drive the screw 32 to rotate, and the first end of the first shaft 11 is fixedly connected to the slider 33. When the second driver 31 rotates, the screw 32 is driven to rotate, and the screw 32 drives the slider 33 to move up and down along the screw, thereby driving the first shaft 11 and the detection disk 21 to move up and down, and at the same time, the pressure head 12 can be driven to move up and down, so that the detection head 10 extends into the water cup rack. When detecting the bottom of the water cup rack, the screw rotates, driving the detection head 10 to move downward, and the detection disk 21 can continuously apply force to the bottom of the water cup rack to detect the strength of the bottom of the water cup rack. The detection disk 21 can limit the movement of the push rod 26, and can also act as a loading component to apply force to the bottom wall of the water cup rack. Preferably, the bottom surface of the pressure head 12 is higher than the bottom surface of the detection disk 21 to prevent interference. The second driving mechanism may also use other linear transmission mechanisms, such as a linear guide structure.

[0041] In one embodiment, the detection device further includes a controller, the first shaft 11 is provided with a first pressure sensor, the push rod 26 is provided with a second pressure sensor 40, and the first driver 23, the second driver 31, the first pressure sensor and the second pressure sensor 40 are all electrically connected to the controller. The first driver 23 and the second driver 31 can use a driving motor. After the initial position of the slider 33 is set, the slider 33 is located at the initial position each time the detection is performed. According to the distance between the slider 33 and the bottom wall of the water cup holder, the movement process of the pressure head 12 in the vertical direction can be determined, thereby controlling the operation process of the second driver 31. When the first shaft 11 moves vertically to the right position, the controller stops the second driver 31, and then controls the first driver 23 to run, driving the pressure head 12 to expand horizontally. The controller can control the first driver 23 to stop according to the pressure value sent to the controller by the second pressure sensor 40. After the detection is completed, the pressure head 12 and the slider 33 can be automatically reset one after another. In this way, automatic control of the detection process can be achieved, and the accuracy of the detection result can be improved. Of course, the start and stop of the first driver 23 and the second driver 31 can also be manually controlled.

[0042] In one embodiment, Figure 1 As shown, the detection device further includes a stand, the stand includes a first bracket 50, the screw rod 32 includes a screw rod support 321, and the screw rod support 321 is arranged on the first bracket 50 to fix the screw rod transmission mechanism.

[0043] In one embodiment, reference Figure 4 and Figure 5As shown, the stand also includes a fixture table 60, and the fixture table 60 includes a second bracket 61 and a plurality of chucks 62, each of which is arranged on the second bracket 61, and the clamping surface of the chuck 62 is adapted to the outer wall of the cup holder. For example, when the outer wall of the car cup holder is cylindrical, the clamping surface of the chuck 62 is set as an arc surface, and when the outer wall of the car cup holder is rectangular, the clamping surface of the chuck 62 is set as a rectangular surface. The second bracket 61 is provided with a plurality of second long holes 611, and the second long holes 611 extend along the four corners of the top surface of the second bracket 61, and the chuck 62 is provided with a first through hole 621 adapted to the second long hole 611. The first through hole 621 can be set as a threaded hole, and the chuck 62 is fixed to the second bracket 61 by passing a bolt through the second long hole 611 and screwing into the first through hole 621. The first through hole 621 can also be set as a light hole, and the bolt is passed through the first through hole 621 and the second long hole 611 and then fastened with a nut. The chuck 62 is detachably connected to the second bracket 61, and the corresponding chuck 62 can be replaced according to the cup holder to be detected. Preferably, the chuck 62 can be set to four, and the chuck 62 is roughly L-shaped, and the second long hole 611 extends along the four corners of the top surface of the second bracket 61, including the second long hole 611 extending toward the top corner, and can also extend obliquely toward the edge, and two adjacent second long holes 611 are arranged in an eight-shaped shape. When moving along the direction of the second long hole 611, the clamping space enclosed by each chuck 62 can be adjusted to clamp the cup holder or loosen the cup holder, which is suitable for cup holders of various specifications.

[0044] In one embodiment, reference Figure 4 and Figure 6 As shown, the fixture table 60 further includes a third bracket 63 and a table 64 disposed on the third bracket 63, the table 64 is provided with a cross-shaped through slot 641, and a screw 67 is disposed in the cross-shaped through slot 641; the second bracket 61 is fixedly disposed on a first chassis 65, the first chassis 65 is disposed above the table 64, a second chassis 66 is disposed below the table 64, and the first chassis 65 and the second chassis 66 are both threadedly connected to the screw 67. The first bracket 50 can be disposed on the table 64.

[0045] Specifically, a threaded blind hole can be provided on the lower surface of the first chassis 65, and a threaded through hole can be provided on the second chassis 66. Rotating the second chassis 66 can make the first chassis 65 and the second chassis 66 clamp the table 64, and fix the first chassis 65 to the table 64; rotating the second chassis 66 in the opposite direction can make the first chassis 65 and the second chassis 66 loosen the table 64, and the screw 67 can be moved along the cross-shaped through groove 641 to adjust the relative position of the detection head 10 and the fixture table 60, so as to facilitate measurement. When the first chassis 65 rotates, it can also rotate with the second bracket 61 and the clamp 62, and thus rotate with the cup holder. For a special-shaped cup holder, the inner wall of the cup holder can also be well fitted with the pressure head 12, so that the pressure head 12 applies positive force to the inner wall of the cup holder.

[0046] The present invention also provides a method for detecting abuse of a water cup holder, which is applied to the above-mentioned detection device, and the method comprises:

[0047] Control the second driver 31 to operate so that the detection head 10 extends into the water cup holder;

[0048] The second driver 31 is controlled to run, and the second driver 31 drives the detection plate 21 to move toward the bottom wall of the water cup holder, and applies pressure to the bottom wall of the water cup holder until the detection value of the first pressure sensor changes to the first pressure value, and then the second driver 31 is controlled to stop, and the second driver 31 is unloaded after the time t1 is maintained;

[0049] The first driver 23 is controlled to run, and the first driver 23 drives the driving disk 22 to rotate, so that the pressure head 12 moves toward the inner wall of the cup holder, and loads pressure on the inner wall of the cup holder until the detection value of the second pressure sensor 40 changes to the second pressure value, and then the first driver 23 is controlled to stop and unload after the time t2.

[0050] During the test, the cup holder is clamped on the fixture table 60 by the clamp 62, and the abuse strength of the bottom wall and the inner wall of the cup holder can be tested respectively. When the second driver 31 is running, the screw rod 32 is driven to rotate, and the screw rod 32 drives the slider 33 to move downward. The slider 33 moves downward with the first shaft 11 and the detection plate 21, so that the detection head 10 can be extended into the inside of the cup holder. After the detection plate 21 contacts the bottom wall of the cup holder, the second driver 31 continues to run, and a force can be applied to the bottom wall of the cup holder. When the detection plate 21 does not contact the bottom wall of the cup holder, the detection value of the first pressure sensor is 0. When the detection value of the first pressure sensor changes to the first pressure value, the loading pressure reaches the requirement. After the holding time t1, it can be unloaded to realize the Z-direction loading of the cup holder. In order to make the test result accurate, when clamping the cup holder, a gap can be made between the bottom of the cup holder in contact with the detection plate 21 and the first chassis 65, so that the bottom of the cup holder is suspended.

[0051] When the first driver 23 is running, it drives the second shaft 24 to rotate, the second shaft 24 rotates with the first gear 25, the first gear 25 drives the second gear 221 to rotate, the second gear 221 rotates with the driving disk 22, and pushes the guide column 261 to move along the first long hole 222, which can drive the pressure head 12 to expand and load in the direction of the inner wall of the water cup holder. When the pressure head 12 is not in contact with the inner wall of the water cup holder, the detection value of the second pressure sensor 40 is 0. When the detection value of the second pressure sensor 40 changes to the second pressure value, the loading pressure reaches the requirement, and it can be unloaded after the holding time t2, realizing the X-direction and Y-direction loading of the water cup holder.

[0052] After the inspection is completed, the cup holder can be removed from the fixture table 60 and visually inspected to see if there are no cracks, functional failures, surface color changes and structural changes on the cup holder, and if there is no noise when the cup holder is used and the roller shutter operating force meets the design requirements, the cup holder is qualified.

[0053] Preferably, the first pressure value is set to one of 300-800N, the second pressure value is set to one of 75-150N, and the time t1 and t2 are set to one of 5-100s. For example, the first pressure value can be set to 300N, 350N, 400N, 450N, 500N, 550N, 600N, 650N, 700N, 750N or 800N, etc.; the second pressure value can be set to 75N, 80N, 85N, 90N, 95N, 100N, 105N, 110N, 115N, 120N, 125N, 130N, 135N, 140N, 145N or 150N, etc.; the time t1 and t2 can be set to 5s, 10s, 15s, 20s, 25s, 30s, 35s, 40s, 45s, 50s, 55s, 60s, 65s, 70s, 75s, 80s, 85s, 90s, 95s or 100s, etc. The first pressure value, the second pressure value and the corresponding loading time can be appropriately combined. When the pressure value is larger, the loading time can be reduced, and when the pressure value is smaller, the loading time can be increased.

[0054] The detection device drives the first shaft and the detection disk to move downward through the second driver, so that the detection head can be extended into the inside of the cup holder, and then the second shaft is driven to rotate through the first driver, the second shaft rotates with the first gear, the first gear drives the second gear to rotate, and the second gear rotates with the driving disk.
