[0026] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0027] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified and limited, the terms "first" and "second" are for the purpose of clearly describing the numbering of product components and do not represent any substantial difference. The terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances. In addition, the meaning of "multiple" is two or more.

[0028] like Figure 1 As shown, the opening and closing test device provided by the embodiment of the present invention includes a transmitting unit 1 and a receiving unit 2. The transmitting unit 1 and the receiving unit 2 are arranged opposite each other, and the transmitting unit 1 is used to send multiple optical signals 11 to the receiving unit 2. The multiple optical signals 11 are arranged in parallel along the length of the transmitting unit 1. A mounting position is provided between the transmitting unit 1 and the receiving unit 2. The mounting position is used to mount the product under test. When the rotating portion 62 of the product under test rotates relative to the rotating shaft 61, the rotating portion 62 can block some of the optical signals 11.

[0029] Specifically, the transmitting unit 1 and the receiving unit 2 are designed as elongated strips. Optionally, the transmitting unit 1 and the receiving unit 2 are arranged in parallel. One side of the transmitting unit 1 in the longitudinal direction transmits multiple optical signals 11 to the receiving unit 2. The multiple optical signals 11 are arranged along the length of the transmitting unit 1, forming a signal grating between the transmitting unit 1 and the receiving unit 2. The optical signal emitted by the transmitting unit 1 can be a visible light or infrared light signal that can be blocked by objects.

[0030] During use, the product to be tested is installed at the installation position, that is, between the transmitting unit 1 and the receiving unit 2. Optionally, the rotating shaft 61 of the product to be tested is arranged in a longitudinal direction perpendicular to the transmitting unit 1. Then the rotating part 62 of the product to be tested is controlled to rotate relative to the rotating shaft 61. Within the rotation range of the rotating part 62, the rotating part 62 can block part of the light signal 11. And during the entire rotation process of the rotating part 62, when the rotating part 62 is at different rotation angle positions, it will block different light signals 11. During the opening and closing process, based on the changes in the light signal 11 received by the receiving unit 2, and the relative position of the rotating shaft 61 and the light signal 11, the real-time rotation angle of the rotating part 62 and the time it takes for the rotating part 62 to rotate from the starting position to the end position can be obtained. The real-time opening and closing angle and opening and closing speed of the product to be tested can be obtained by calculation.

[0031] The opening and closing test device provided by the present invention comprises a transmitting unit 1 and a receiving unit 2. The transmitting unit 1 transmits a plurality of optical signals 11 arranged along the length of the transmitting unit 1 to the receiving unit 2. The rotating portion 62 of the product under test, located between the transmitting unit 1 and the receiving unit 2, blocks the optical signals 11 during rotation. Based on the real-time blocking of the optical signals 11, the opening and closing angle and speed of the product under test can be tracked in real time. During repeated opening and closing tests, a deviation value can be derived based on the comparison of the angle and speed values ​​measured each time, thereby achieving quantitative tracking of the stability of the rotating shaft.

[0032] Optionally, in an embodiment of the present invention, transmitting unit 1 is a grating transmitting unit, and receiving unit 2 is a grating receiving unit. The grating transmitting unit and the grating receiving unit constitute a grating scale sensor. The grating transmitting unit is capable of emitting stable, high-intensity light signals. The light signals emitted by the grating transmitting unit are modulated to form specific grating patterns or moiré fringes, which are then captured by the grating receiving unit and converted into electrical signals. By measuring changes in the electrical signals, motion information such as the rotation angle and rotation speed of the rotating portion 62 can be accurately calculated, achieving precise measurement of the opening and closing angle and speed.

[0033] It should be noted that the transmitting unit 1 and receiving unit 2 of the embodiment of the present invention are not limited to the grating scale structure, and can also be replaced by other structures.

[0036] Specifically, the fixing member 32 can be a pressure strip or a pressure plate. The fixing member 32 is connected to the base 31 by bolts. A rotating part 62 of the product to be tested is located between the fixing member 32 and the base 31. The fixing member 32 is locked on the base 31 by bolts, thereby pressing the product to be tested to prevent the product to be tested from moving during the opening and closing test and affecting the accuracy of the test results.

[0037] The opening and closing test device provided in this embodiment of the utility model also includes a base 31 and a mounting assembly. The mounting assembly is fixed to the base 31. The transmitting unit 1 and the receiving unit 2 are mounted to the base 31 via the mounting assembly. The height of the transmitting unit 1 and the receiving unit 2 relative to the base 31 is adjustable. By adjusting the height of the transmitting unit 1 and the receiving unit 2, it can accommodate test samples of different sizes.

[0038] Optionally, the transmitting unit 1 and the receiving unit 2 are mounted on the mounting assembly in an adjustable manner. Specifically, the transmitting unit 1 and the receiving unit 2 are connected to the mounting assembly via connectors, and the positions of the connectors on the mounting assembly are adjustable, thereby achieving adjustable height of the transmitting unit 1 and the receiving unit 2 relative to the base 31.

The mounting assembly has a plurality of first locating holes 43 distributed along the height direction, which mate with the first locating pin 51. The mounting assembly also has a plurality of second locating holes 44 distributed along the height direction, which mate with the second locating pin 52.

[0041] Optionally, one end of the transmitting unit 1 and one end of the receiving unit 2 are connected to the mounting assembly via a first locating pin 51, and accordingly, the mounting assembly is provided with two vertical rows of first locating holes 43 corresponding to the two first locating pins 51. The other end of the transmitting unit 1 and the other end of the receiving unit 2 are connected to the mounting assembly via a second locating pin 52, and accordingly, the mounting assembly is provided with two vertical rows of second locating holes 44 corresponding to the two second locating pins 52.

That is, the first locating pin 51 is provided through one end of the transmitting unit 1, one end of the receiving unit 2, and the first locating hole 43 on the mounting assembly, so that the heights of one end of the transmitting unit 1 and one end of the receiving unit 2 can be adjusted simultaneously.

[0044] The other opposing ends of the transmitting unit 1 and the receiving unit 2 are connected to the mounting assembly via a second locating pin 52. Specifically, the second locating pin 52 extends through the other end of the transmitting unit 1, the other end of the receiving unit 2, and the second locating hole 44 on the mounting assembly, allowing for simultaneous height adjustment of the other ends of the transmitting unit 1 and the other ends of the receiving unit 2. The heights of the transmitting unit 1 and the receiving unit 2 can be adjusted by replacing the first locating hole 43 that mates with the first locating pin 51 and the second locating hole 44 that mates with the second locating pin 52.

[0045] Optionally, the mounting assembly includes a plurality of first positioning posts 41 and a plurality of second positioning posts 42. The transmitting unit 1 is sleeved on the plurality of first positioning posts 41, and the receiving unit 2 is sleeved on the plurality of second positioning posts 42.

[0048] It is understood that the two first positioning posts 41 and the two second positioning posts 42 form four legs of the transmitting unit 1 and the receiving unit 2. By adjusting the connection between the transmitting unit 1 and the receiving unit 2 and the legs at different heights, the height of the transmitting unit 1 and the receiving unit 2 can be adjusted.

[0049] The first positioning hole 43 extends through one of the first and second positioning posts 41, 42, and the second positioning hole 44 extends through the other first and second positioning posts 41, 42.
