Abstract

[0002] An automobile armrest box is a special interior device for automobiles, and people can open it to place some commonly used car supplies.
[0003] For example, a common double-door armrest box, as Figure 1 shown, when the armrest box switch is pressed, the cover plate 1, the pressure plate 2, and the vertical hook 3 are all fixed by a torsion spring 4. The switch drives the vertical hook 3 to act through the pressure plate 2, so that the vertical hook 3 releases the armrest box cover plate 1, thereby opening the armrest box. However, during long-term use, components such as the connecting parts and the torsion spring 4 inside the double-door armrest box are prone to fatigue damage.
[0004] Therefore, it is necessary to detect the fatigue strength of the double-door armrest box and detect the maximum number of opening and closing times that the double-door armrest box can bear. Therefore, the armrest box durability and fatigue detection equipment came into being. During the detection process, the pressure plate and the vertical hook inside the double-door armrest box are used as linkage components, and their movement positions need to be accurately detected to determine whether the double-door armrest box is damaged. Therefore, how to accurately detect the positions of linkage components such as the pressure plate and the vertical hook is a problem that needs to be solved in the detection equipment. Summary of the Invention
[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a two-way position detection device that can accurately detect the fatigue strength of a double-door armrest box and improve product quality.

[0022] In order to make the content of the utility model be more clearly understood, the following further details the utility model according to specific embodiments and in conjunction with the accompanying drawings.
[0023] Such as Figure 2As shown in the figure, this embodiment provides a bidirectional position detection device, which includes a power component, a bracket component, a connecting block 7, a first mounting seat 101, a second mounting seat 102, a first sensing component, a second sensing component, and a photoelectric sensor 9.
[0024] As Figure 2 shown in the figure, the power component of this embodiment is fixed at one end of the bracket component, one end of the connecting block 7 is connected to the power component, and the power component drives the connecting block 7 to move on the bracket component. The power component includes a cylinder 51, a flange 52, and a connecting piece 53. The flange 52 is fixed at one end of the bracket component, and the piston rod of the cylinder 51 is connected to one end of the connecting block 7 through the connecting piece 53. The bracket component includes a bottom plate 61, a support column 62, and a base 63. The bottom plate 61 is fixed on the base 63 through the support column 62. A slider 71 is connected to the bottom of the connecting block 7, and a guide rail 72 is fixed on the bottom plate 61. The slider 71 cooperates with the guide rail 72 for sliding. During detection, the cylinder 51 is ventilated to push out the connecting block 7. As Figure 3 shown in the figure, the second sensing component is brought into contact with the side wall of the vertical hook 3 for collision detection.
[0025] As Figure 1 shown in the figure, the first mounting seat 101 of this embodiment is fixed at the other end of the connecting block 7, and the second mounting seat 102 is connected to the first mounting seat 101 through a connecting rod. The first sensing component is fixed on the first mounting seat 101, and the second sensing component is slidably connected to the second mounting seat 102. The first sensing component includes a first sensing probe 81 and a second sensing probe 82, and the second sensing component includes a third sensing probe 83 and a fourth sensing probe 84. The first sensing probe 81 and the second sensing probe 82 are respectively fixed in the first mounting seat 101, and the third sensing probe 83 and the fourth sensing probe 84 are respectively slidably connected to the second mounting seat 102. After the third sensing probe 83 slides, it comes into contact with the first sensing probe 81, and after the fourth sensing probe 84 slides, it comes into contact with the second sensing probe 82. The photoelectric sensor 9 is arranged on the first mounting seat 101. The photoelectric sensor 9 of this embodiment is a diffuse reflection infrared sensor, and the model is E3JK-DR12-J diffused. As Figure 4 shown in the figure, the photoelectric sensor 9 is used for position detection of the vertical hook 3.
[0026] The working principle of the bidirectional position detection device in this embodiment is as follows:
[0027] As Figure 1 shown in the figure, when the armrest box switch is pressed, the switch presses down the pressure plate 2, and the pressure plate 2 presses the lower end of the vertical hook 3, causing the upper end of the vertical hook 3 to rotate and release the cover plate 1, thereby opening the armrest box. During detection, the switch and the cover plate 1 are respectively pressed down by an automatic pressing device, and the cover plate 1 can be automatically opened and closed to perform fatigue strength detection for hundreds or thousands of times.
[0028] At the start of the detection, the automatic pressing device presses the switch, and the cover plate 1 can be opened. At this time, the cylinder 51 pushes out the first induction component and the second induction component, so that the second induction component contacts the side wall of the vertical hook 3.
[0029] Then, the automatic pressing device presses down the cover plate 1. If the cover plate 1 can be normally closed and locked, since the vertical hook 3 is fixed by the torsion spring 4, when locked, the vertical hook 3 will move outward and then return to lock the cover plate 1. When the vertical hook 3 moves outward, it will collide with the induction probe of the second induction component, and then the induction probe of the second induction component will slide outward to collide with the two induction probes of the first induction component. Then, the first induction component transmits the collision signal to the host computer, indicating that it is detected that the vertical hook 3 can be normally released and locked. If the collision signal of the vertical hook 3 is not detected, it means that the vertical hook 3 cannot act normally and there is a fault in the armrest box, which is checked by the tester.
[0030] However, when the automatic pressing device presses down the cover plate 1, situations such as excessive pressure or other vibrations may occur, which may also cause the vertical hook 3 to act erroneously. At this time, even if there is a fault in the armrest box, such as the torsion spring 4 is broken and has no elasticity or the pressing plate 2 is broken and damaged, accurate detection cannot be performed based on the collision signal. Therefore, the photoelectric sensor 9 is added. The photoelectric sensor 9 emits infrared rays to the side wall of the vertical hook 3 and then receives them after reflection by the vertical hook 3, and the time from the emission to the reception of the infrared rays can be calculated.
[0031] If the armrest box can be normally closed, after the cover plate 1 is closed, the vertical hook 3 will move and then return to the locked position. In this case, the time for the photoelectric sensor 9 to emit infrared rays to the vertical hook 3 at the locked position and then return is T. However, if there is a fault in the armrest box and the movement of the vertical hook 3 is an erroneous action caused by vibration, the vertical hook 3 cannot return to the locked position after the erroneous action. At this time, the time from the emission to the reception of the infrared rays will be less than T, indicating that this collision signal is caused by an erroneous action.
[0032] Through the double detection of the position of the vertical hook 3 by the collision signal and the infrared signal, the accuracy of the detection is ensured.
[0033] In the above-described specific embodiments, the technical problems solved, the technical solutions, and the beneficial effects of the present utility model are further described in detail. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model.
