[0050] Example:

[0051] See also Figures 1 to 7The self-resetting displacement device designed for the automated vehicle base signal transponder in the preferred embodiment of the present invention comprises a base plate 1, a counterweight mounting plate 2, a rotating assembly 3 and a rotating drive assembly 4. The base plate 1 is fixed below the rail 6, and the rotating assembly 3 is rotatably connected to the base plate 1. The rotating assembly 3 can realize rotational motion under the drive of the rotating drive assembly 4, thereby realizing the switching between the working state and the folding state.

[0052] In the working state (i.e., the initial state), the rotating component 3 rotates under the drive of the rotating drive component 4, so that the carrying component 5 rotates from the bottom of the rail 6 to the position between the two rails 6, that is, the signal transponder 503 extends a certain distance above the ground of the maintenance trench, providing a guarantee for the accurate storage and docking of fully automatic vehicles, and realizing the precise parking of fully automatic vehicles in the vehicle base; in the folded state, the carrying component 5 arranged at the end of the rotating component 3 is away from the center of the maintenance trench, so as to realize the normal operation of the maintenance trench and ensure that maintenance workers and automated maintenance robots can pass smoothly in the maintenance trench.

[0053] Specifically, the substrate 1 in the preferred embodiment is a plate-like structure, which is arranged at the bottom of the rail 6 to provide support for the arrangement of other components of the displacement device. In the preferred embodiment, the substrate 1 is fixed to the bottom of the rail 6 by two clips 101 arranged on both sides of the rail 6. The clips 101 are in an "L-shaped" structure, one end of which is fixed to the substrate 1 and the other end is clipped to the bottom of the rail 6. Through the above arrangement, not only can the arrangement of the substrate 1 be realized, but also the interference of the substrate 1 with the track running area after the arrangement of the substrate 1 can be avoided.

[0054] Further, in the preferred embodiment, other components of the displacement device are arranged below the base plate 1, wherein the corresponding rotating assembly 3 is provided with a rotating member 102 on the bottom surface of the base plate 1 near one end of the maintenance trench, for the rotating connection of the end of the rotating assembly 3. In actual arrangement, the rotating member 102 is as follows: Figure 4 however, it is obvious that the rotating member 102 can be replaced with other structural forms in the prior art according to actual needs, as long as the rotation control of the end of the rotating assembly 3 can be satisfied.

[0055] Meanwhile, in a preferred embodiment, the rotating assembly 3 includes a first rotating rod 301 and a second rotating rod 302. One end of the first rotating rod 301 is connected to the rotating member 102, and the first rotating rod 301 can be driven to rotate around the end under the rotation of the rotating member 102. Accordingly, one end of the second rotating rod 302 is fixedly connected to one side of the first rotating rod 301, and can rotate synchronously with the first rotating rod 301.

[0056] In actual setting, the second rotating rod 302 is in a horizontal state when the rotating assembly 3 is in a folded state, and in a vertical state when the rotating assembly 3 is in operation, that is, the rotating assembly 3 rotates 90° when it is converted from the folded state to the operating state. Obviously, the above setting angle can be adjusted according to actual needs, which can be determined according to specific circumstances.

[0057] Furthermore, a guide member 303 is provided on the second rotating rod 302 along its length direction, and a sliding member 304 is provided corresponding to the guide member 303. The sliding member 304 is matched on the guide member 303 and can slide back and forth along the axis of the guide member 303. In actual configuration, the combination of the sliding member 304 and the guide member 303 can be a combination of a slider and a slide rail, such as Figure 1 As shown in , it can also be a combination of a guide groove and a sliding pin, which can also be optimized according to actual conditions.

[0058] Preferably, a limiting member 305 is provided on the end of the first rotating rod 301 or the second rotating rod 302 close to the base plate 1, and correspondingly, a blocking member 306 is provided at the bottom of the base plate 1, so that after the first rotating rod 301 rotates from the folded state to the right position, the limiting member 305 just matches and abuts against the blocking member 306. Figure 2 In the preferred embodiment, the limiter 305 and the blocking member 306 are plate-like structures extending horizontally, the limiter 305 is a plate structure extending longitudinally along the rail 6, and the blocking member 306 is a plate structure extending transversely along the rail 6, and the two are just abutted and matched after the rotating assembly 3 rotates to the right position, thereby avoiding excessive rotation of the rotating assembly 3 and ensuring that the signal transponder 503 on the carrying assembly 5 can be accurately rotated to the right position. Obviously, in actual setting, another blocking member can also be set on the bottom surface of the other end of the base plate 1 for limiting and blocking when the rotating assembly 3 is retracted.

[0059] Further preferably, when the blocking member 306 is actually provided, one end thereof abutting against the limiting member 305 can be provided as an elastic end, so that the contact between the blocking member 306 and the limiting member 305 can be buffered to a certain extent. For example, the blocking member 306 is provided as a spring shock absorber to ensure that the rotating assembly 3 can be effectively damped after being rotated into position, thereby avoiding excessive rotation of the rotating assembly 3. Of course, it is understandable that the spring shock absorber and the blocking member 306 can also be provided at the same time, and the blocking member provided when the corresponding rotating assembly 3 is retracted can also be provided as the above-mentioned damping form.

[0060] In addition, in actual application, a sensor component can be set for the working state and / or folding state of the rotating component 3 to display whether the rotation or retraction of the rotating component 3 is in place. Moreover, it is preferred that an alarm component is set corresponding to each sensor component. Once the sensor component shows that the movement is not in place, an alarm can be sounded through the corresponding alarm component, and then the maintenance personnel can perform corresponding control and adjustment operations.

[0061] Specifically, in a preferred embodiment, a pressure sensor is provided at the bottom of the base plate 1 for the stopper 305, so that after the rotating assembly 3 rotates to the right position, the stopper 305 can abut against the pressure sensor, and the state of the pressure sensor is used to determine whether the rotating assembly 3 is rotated to the right position. At the same time, another pressure sensor can be provided below the base plate 1 for the connecting rod 501 of the rotating assembly 3 or the carrying assembly 5, so that after the rotating assembly 3 is retracted to the right position, the rotating assembly 3 or the connecting rod 501 can correspondingly abut against the pressure sensor, and the pressure sensor is used to determine whether the rotating assembly 3 is retracted to the right position.

[0062] Obviously, according to the actual design and application needs, the above-mentioned sensing component can also be implemented in other forms. For example, in another preferred embodiment, optical sensors are respectively arranged on the rotating component 3 and the base plate 1, and one of the optical sensors emits sensing light and the other optical sensor receives the sensing light to judge whether the rotating component is rotated to the right position. Similarly, a similar optical sensing sensor can also be arranged corresponding to the retraction of the rotating component 3 to judge whether the folding state is in place.

[0063] Further, see Figures 1 to 5 In the preferred embodiment, a rotation drive assembly 4 is also provided corresponding to the rotation assembly 3, which is mainly used for rotation drive and rotation retraction of the rotation assembly 3. It includes a driving component and a retraction component. In the preferred embodiment, the driving component is composed of a counterweight 401 and a driving rope 402, and a counterweight mounting plate 2 is provided corresponding to the driving component. The plate surface of the counterweight mounting plate 2 is arranged vertically, and its plate surface is preferably perpendicular to the longitudinal direction of the rail 6, that is, the extension direction of the plate surface of the rail 6 is the transverse direction of the rail 6.

[0064] More specifically, the top of the counterweight mounting plate 2 is fixed to the bottom surface of the base plate 1, and at least two pulleys are arranged on the side thereof close to the rotating assembly 3, for matching the driving rope 402. In a preferred embodiment, the number of pulleys is 3, namely the first pulley 201, the second pulley 202, and the third pulley 203. The second pulley 202 and the third pulley 203 are arranged at one end of the counterweight mounting plate 2, and the first pulley 201 is arranged at the other end of the counterweight mounting plate 2. Then, one end of the driving rope 402 matches the counterweight 401, and the other end thereof passes over the top of the first pulley 201 and then passes over the bottom of the second pulley 202 in sequence, and after passing over the top of the third pulley 203, it is matched and connected to the sliding member 304.

[0065] Through the above arrangement, the counterweight 401 can pull the drive rope 402 to move under the action of its own weight, thereby driving the unlocked rotating assembly 3 from the folded state to the working state. Obviously. In actual arrangement, it is only necessary to match and connect one end of the drive rope 402 to the end of the second rotating rod 302 to realize its rotation drive, and the sliding member 304 can be regarded as a connecting member fixed to the end of the guide member 303. Although the above arrangement can meet the actual driving requirements, it will result in a longer length of the drive rope 402 and a longer driving stroke of the counterweight 401. Therefore, in actual arrangement, it is still preferred to connect the end of the drive rope 402 to the movable sliding member 304.

[0066] Furthermore, the retracting member in the preferred embodiment is arranged at the bottom of the end of the base plate 1 away from the rotating member 102, for retracting the rotating assembly 3 from the working state. In actual arrangement, the retracting member can be preferably arranged in different forms according to design requirements.

[0067] For example, in a preferred embodiment, the retrieving component includes a servo motor 403, a retrieving wheel 404 and a retrieving rope 405, such as Figure 2 As shown in , one end of the retracting rope 405 is connected to the back of the first rotating rod 301, and the other end thereof is connected to the retracting wheel 404. At the same time, the retracting wheel 404 is coaxially matched with the output shaft of the servo motor 403. Through the operation of the servo motor 403, the retracting rope 405 on the retracting wheel 404 can be realized, thereby realizing the retraction of the rotating assembly 3. After the rotating assembly 3 is retracted into place, it is only necessary to lock the servo motor 403 to ensure that the rotating assembly 3 remains in the folded state. Once the servo motor 403 is unlocked, the rotating assembly 3 can be quickly extended under the action of the counterweight 401, thereby realizing self-reset.

[0068] Obviously, in addition to the above-mentioned form, the retracting component can also be set in other forms. For example, in another preferred embodiment, the retracting component is set in the form of a telescopic cylinder / hydraulic cylinder, one end of the cylinder body is hinged to the bottom of the base plate 1, and the end of its output shaft is hinged to the back of the first rotating rod 301. The retraction of the output shaft can achieve the retraction of the rotating assembly 3. Obviously, when the retracting component is set in the above-mentioned form, it can also essentially play the role of a driving component, that is, through the extension of the output shaft, the rotating assembly 3 is switched from the folded state to the working state.

[0069] Furthermore, a carrying component 5 is provided on the rotating component 3 for carrying the signal transponder 503. In a preferred embodiment, the carrying component 5 includes a connecting rod 501 and a mounting seat 502, one end of the connecting rod 501 is connected to the first rotating rod 301, and the other end is provided with a mounting seat 502, and the signal transponder 503 is provided on the mounting seat 502. Preferably, when the rotating component 3 is rotated into place, the connecting rod 501 is just in a horizontal state, and the mounting seat 502 supports the signal transponder 503 in the middle position of the two rails 6 (the top surface of the signal transponder 503 is a certain distance below the height of the rail surface of the two rails 6, usually 120 mm), and the top surface of the signal transponder 503 is arranged horizontally. Accordingly, when the rotating component 3 is in a folded state, the connecting rod 501 is preferably in a vertical state, and the top surface of the signal transponder 503 is in a vertical state, such as Figure 7 as shown in .

[0070] For the self-resetting displacement device in the preferred embodiment, its working state is as follows: Figure 2 As shown in the folded state Figure 7 The working process is as follows:

[0071] When the position changing device needs to switch from the folding state to the working state, it only needs to unlock the servo motor 403, so that the rotating assembly 3 can realize self-reset and rotate to the working state under the drive of the counterweight 401. After being extended to the right position, the corresponding sensor assembly on the position changing device can be used to determine whether the extension is in place.

[0072] On the contrary, when the displacement device needs to switch from the working state to the folding state, it is only necessary to control the servo motor 403 to work and retract the retrieval rope 405 to the retrieval wheel 404. At this time, the second rotating rod 302 rotates and pulls the driving rope 402, so that the counterweight 401 is lifted to a certain height driven by the driving rope 402 until the corresponding sensor component on the displacement device determines that the device is retracted into place. Thereafter, the servo motor 403 is locked and the displacement device can be locked in the folding state.

[0073] The self-resetting displacement device of the automated vehicle base signal transponder in the present invention has a simple structure and is simple to set up. It can quickly realize the switching of the signal transponder between the working state and the non-working state, thereby ensuring the accurate guidance of the fully automatic vehicle when entering the warehouse, and the rapid restoration of the unblocked maintenance trench after the fully automatic vehicle enters the warehouse. It provides protection for maintenance personnel or automated maintenance equipment in the maintenance trench, ensures the safety and accuracy of the fully automatic vehicle entering the warehouse and parking, solves the problem of the signal transponder in the maintenance trench of the automated vehicle base hindering the maintenance operation, improves the efficiency of the maintenance of the fully automatic vehicle, reduces the cost of the maintenance of the fully automatic vehicle, and has good practical value and promotion value.

[0074] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
