The specific structural and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments described herein.

Figure 1 is a structural schematic diagram of a state acquisition device provided in an embodiment of the present application, Figure 2 is a cross-sectional view of a acquisition member 300 provided in an embodiment of the present application, Figure 3 is a partial cross-sectional view of a sliding portion 302 provided in an embodiment of the present application, Figure 4 is a partial cross-sectional view of a box cover in a first position provided in an embodiment of the present application, and Figure 5 is a partial cross-sectional view of a box cover in a second position provided in an embodiment of the present application.

As shown in FIG1 , a state acquisition device for turning over a box cover is provided, the state acquisition device comprises a connecting member 100 , a transmission member 200 and a acquisition member 300 , wherein:

As shown in FIG1 , one end of the connecting member 100 is fixedly connected to the box cover and arranged on the rotating shaft of the box cover. The box cover is fixedly connected to the connecting member 100 and drives the connecting member 100 to rotate synchronously with the box cover when the box cover is opened and closed. The connecting member 100 is arranged at the rotating shaft of the box cover so that when the box cover rotates, the connecting member 100 only rotates axially without relative displacement, thereby ensuring the collection reliability.

As shown in FIG. 1 , one end of the transmission member 200 is connected to the connecting member 100 , and the rotation of the connecting member 100 drives the transmission member 200 to move in conjunction.

As shown in Figures 1 and 2, the collecting member 300 includes a shell 301, a sliding portion 302 reciprocatably arranged in the shell 301, and a triggering portion 303 fixed at both ends of the shell 301. The side wall of the shell 301 is provided with a connecting groove 304, and one end of the transmission member 200 away from the connecting member 100 passes through the connecting groove 304 and is hinged to the sliding portion 302. When the transmission member 200 rotates following the connecting member 100, the transmission member 200 drives the sliding portion 302 to trigger one of the triggering portions 303.

As shown in Figures 1, 2, 4 and 5, the sliding part 302 is located between the two triggering parts 303 and moves back and forth. One end of the transmission member 200 is hinged on the sliding part 302, and when the transmission member 200 rotates, the hinge relationship between the transmission member 200 and the sliding part 302 causes the slider to be pushed to move between the two triggering parts 303. After the sliding part 302 moves a certain distance, the sliding part 302 triggers one of the triggering parts 303 to output a signal that the box cover is in this position, thereby completing the collection operation of the box cover status.

As shown in FIGS. 1 , 2 , 4 and 5 , in an optional embodiment, the working principle of the state acquisition device in the present application is as follows: the state acquisition device includes a connecting member 100 fixedly connected to the box cover at one end, the connecting member 100 is arranged on the rotating shaft of the box cover, a transmission member 200 is connected to the connecting member 100, one end of the transmission member 200 is connected to a collection member 300, the collection member 300 includes a shell 301, a sliding portion 302 reciprocally arranged in the shell 301, and a triggering portion 303 fixed at both ends of the shell 301, a connecting groove 304 is provided on the side wall of the shell 301, and one end of the transmission member 200 away from the connecting member 100 passes through the connecting groove 304 and is hinged to the sliding portion 302, And when the transmission member 200 rotates following the connecting member 100, the transmission member 200 drives the sliding part 302 to trigger one of the triggering parts 303. During actual operation, when the box cover is driven to open or close around the rotating axis, the connecting member 100 rotates synchronously and drives the transmission member 200 to move. One end of the transmission member 200 pushes the sliding part 302 to move in the shell 301, and the transmission member 200 rotates relative to the sliding part 302. When the sliding part 302 is located at different positions, the triggering parts 303 located at both ends of the shell 301 can be triggered respectively, so that the position of the box cover in different states can be collected, so as to confirm the opening and closing state of the box cover in this working condition, and improve the reliability of the box cover after the action.

As shown in FIG. 1 and FIG. 2 , in an optional implementation, the two triggering parts 303 are movably connected to the housing 301 , and the two triggering parts 303 can be moved closer to or farther from each other.

The two trigger parts 303 are movably arranged at both ends of the shell 301. By operating the two trigger parts 303 to move closer to or farther away from each other, the distance between the two trigger parts 303 is changed, and then the working stroke required for the slider to trigger the trigger part 303 is adjusted. During the opening and closing process of the box cover, the stroke error of the box cover in different states can be compensated, thereby improving the accuracy of the box cover state acquisition results.

As shown in FIG. 1 and FIG. 2 , in an optional embodiment, a movable cover 401 is provided between the trigger portion 303 and the shell 301 , one end of the movable cover 401 is sleeved on the end of the shell 301 , and the trigger portion 303 is passed through the other end of the movable cover 401 .

Specifically, the trigger part 303 is set at both ends of the shell 301 through the movable cover 401. The adjustment of the distance between the trigger parts 303 is completed through the relative movement of the movable cover 401. Then, under the premise of maintaining the installation reliability of the trigger part 303, the movable adjustment point can be transferred between the movable cover 401 and the shell 301 to improve the overall reliability.

As shown in FIG. 1 and FIG. 2 , in an optional embodiment, a slide groove 402 is provided on the movable cover 401 , a limiting bolt 403 passing through the slide groove 402 is threadedly connected to the housing 301 , and one end of the limiting bolt 403 is used to be pressed onto the movable cover 401 .

Specifically, the limiting bolt 403 is threadedly connected to the shell 301. The movable cover 401 can be pressed onto the object by rotating the limiting bolt 403, thereby keeping the movable cover 401 in a relatively stable position to prevent the movable cover 401 from moving again. The limiting bolt 403 can also be operated to rotate so that one end of the fiber bolt removes the pressure on the movable cover 401. At this time, the movable cover 401 can move back and forth relative to the shell 301, and during the movement of the movable cover 401, the limiting bolt 403 is always kept in the slide groove 402 to facilitate subsequent fixed constraints.

As shown in FIG. 1 , FIG. 2 and FIG. 3 , in an optional implementation, two sensing parts 501 for triggering the triggering part 303 are provided on the sliding part 302 , and a buffer part is provided between the sensing part 501 and the sliding part 302 .

In order to ensure that the triggering part 303 is more reliably and stably triggered by the sliding part 302, two sensing parts 501 corresponding to the triggering part 303 are provided. When the sensing parts 501 follow the movement of the sliding part 302, they can respectively trigger the triggering part 303, thereby improving the triggering stability.

A buffer portion is respectively arranged between the two sensing portions 501 and the sliding portion 302. It should be noted that the two processes from the beginning of opening to the appearance of a gap in the box cover, and from being about to close to being completely closed, are dynamic, and there is no absolute critical value for the opening and closing of the box cover. In addition, there is a transmission gap in the driving member for opening and closing the box cover. In other words, there is a certain execution error in each movement of the box cover. A buffer portion is respectively arranged between the two sensing portions 501 and the sliding portion 302, so that when the sensing portion 501 just triggers a trigger portion 303, the buffer portion can allow the box cover to continue to rotate the calibration stroke, and the sensing portion 501 can always keep triggering the trigger portion 303 under the action of the buffer portion until the box cover moves to the target position, thereby realizing adaptive adjustment and collection of the box cover angle.

As shown in Figures 1, 2 and 3, in an optional embodiment, the buffer portion includes a guide rod 502 fixedly connected to the sliding portion 302, and a guide sleeve 503 fixedly connected to the sensing portion 501, and the guide sleeve 503 is sleeved on the guide rod 502 and can reciprocate along the extension direction of the guide rod 502, and an elastic member 504 is provided between the guide sleeve 503 and the guide rod 502.

Specifically, when the buffering part is operating, under the action of the slider, a sensing part 501 moves toward a corresponding triggering part 303. When the sensing part 501 triggers the triggering part 303, the box cover is not fully opened to the target angle, or is not fully closed to the target angle. As the box cover continues to rotate, the sliding part 302 is also pushed to continue moving. At this time, the sliding part 302 and the sensing part 501 move relative to each other, and the guide rod 502 extends relatively into the guide sleeve 503 to form a buffer. In this process, the box cover rotates to the target position. When the sliding part 302 moves in the direction, the elastic member 504 resists the guide sleeve 503 and the guide rod 502 to reset relative to each other, which is convenient for the buffering operation in the subsequent operation process and improves the reliability.

As shown in FIG. 1 , FIG. 2 and FIG. 3 , in an optional embodiment, a retaining ring 601 is threadedly connected to the trigger portion 303 , and the retaining ring 601 is retained on the housing 301 and restricts the two trigger portions 303 from approaching each other.

The supporting ring 601 is threadedly connected to the trigger part 303. The relative position of the supporting ring 601 on the trigger part 303 can be adjusted by rotating the supporting ring 601. Furthermore, when the supporting ring 601 is supported on the shell 301, when the supporting ring 601 is located at different positions, the trigger part 303 extends to different depths inside the shell 301, that is, the distance between the two trigger parts 303 is different, thereby controlling the trigger stroke between the two trigger parts 303. After adjusting the distance between the trigger parts 303, the operating state of the box cover can be more accurately controlled.

Specifically, the trigger portion 303 can be clamped on the housing 301 through the annular step section and the abutting tube.

As shown in Figures 1, 2 and 3, in an optional embodiment, two connecting grooves 304 are provided and are arranged relatively on both sides of the shell 301. The transmission member 200 is provided with support ears 201 extending into the two connecting grooves 304 respectively, and the support ears 201 are connected to the sliding part 302. The two support ears 201 are more stably connected to the sliding part 302, thereby improving the stability of the displacement of the sliding part 302.

As shown in FIG. 1 , FIG. 2 and FIG. 3 , in an optional embodiment, the state acquisition device further includes a mounting seat 602 , and the acquisition component 300 and the connecting component 100 are respectively arranged on the mounting seat 602 , so as to facilitate installation and positioning through the mounting seat 602 , thereby improving assembly accuracy and reliability.

As shown in Figures 1, 2 and 3, in an optional embodiment, a connecting portion 603 is provided between the connecting piece 100 and the box cover, a hinged ear plate 604 is provided in the middle of the connecting portion 603, one side of the middle connecting portion 603 is fixedly connected to the box cover to maintain the connection stability of the box cover, and the hinged ear plate 604 provided in the middle of the connecting portion 603 is used for hinged lifting mechanism, which is convenient for driving the connecting portion 603 to rotate through the lifting mechanism, thereby driving the rotation of the box cover.
