From the early simple stacking of goods and manual handling, to the later introduction of mechanized equipment to assist operations, and now to highly automated warehousing systems, this development process has greatly improved the efficiency of goods storage and handling. With the continuous advancement of technology, four-way shuttles have emerged as a highly efficient automated handling device.

[0003] Traditional methods for powering and charging four-way shuttles are systematic and standardized. They typically use charging brush plates of specific specifications in conjunction with brush blocks located within the racks. However, existing technologies lack effective temporary power replenishment measures when the four-way shuttle is not in a charging position and its power is insufficient.

[0004] The drawback of existing technology is that when the four-way shuttle vehicle is out of power at a non-charging station, it lacks an effective temporary charging method and cannot restore power in time.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The core of this utility model is to provide an emergency charging structure for a four-way shuttle vehicle.

[0030] Another core aspect of this invention is to provide a four-way shuttle vehicle, including the aforementioned emergency charging structure for a four-way shuttle vehicle.

[0031] like Figure 1 and Figure 2 A specific embodiment of the emergency charging structure for the four-way shuttle vehicle shown includes a first emergency charging port 2 and a second emergency charging port 3. The first emergency charging port 2 is located on the bottom support surface of the vehicle body 1. A charger is installed inside the vehicle body 1. The first emergency charging port 2 is electrically connected to the charger, and the charger is electrically connected to the battery located inside the vehicle body 1. The second emergency charging port 3 is located on the side support surface of the vehicle body 1 and is electrically connected to the charger.

[0032] In existing technology, the bottom of the four-way shuttle vehicle body 1 is equipped with a charging brush plate for charging, and a brush block that cooperates with the charging brush plate is located at a designated position inside the shelf. The power supply route is brush plate → DC contactor → battery → driver → servo motor. However, in actual production operations, when the vehicle is in a non-charging position and its power is insufficient, it cannot be charged by the brush plate and brush block, thus causing congestion in the transport within the shelf.

[0033] In this application, a first emergency charging port 2 and a second emergency charging port 3 are respectively provided on the bottom support surface and the side support surface of the vehicle body 1, wherein the first emergency charging port 2 and the second emergency charging port differ only in their installation positions. Simultaneously, to cooperate with the first emergency charging port 2 and the second emergency charging port 3, a charger is installed in the internal installation space of the vehicle body 1. The charger is electrically connected to the battery inside the vehicle body 1, and both the first emergency charging port 2 and the second emergency charging port 3 are electrically connected to the charger. Thus, by inserting a charging plug into the first emergency charging port 2 or the second emergency charging port 3, the battery inside the vehicle body 1 is charged using the charger, thereby achieving temporary power replenishment for the vehicle. The emergency charging ports are located on the bottom and sides of the vehicle to facilitate manual emergency rescue of the vehicle from the bottom or side of the vehicle body 1, thereby avoiding obstruction of the work passage, and allowing personnel to choose between bottom or side emergency power replenishment depending on convenience.

[0034] The aforementioned emergency charging structure for the four-way shuttle vehicle, by setting a first emergency charging port 2 and a second emergency charging port 3 on the bottom and side of the vehicle body respectively, and adopting a standardized quick connection interface, allows the four-way shuttle vehicle to be conveniently temporarily charged through the emergency charging port when it is out of power at a non-charging position, thereby improving the operational efficiency of the warehousing and logistics system.

[0035] Based on any of the above embodiments, both the first emergency charging port 2 and the second emergency charging port 3 adopt standardized quick connection interfaces, wherein the interface types include, but are not limited to, Anderson interfaces, J1772 interfaces or CHAdeMO interfaces.

[0036] Specifically, the Anderson interface is characterized by convenient connection and good conductivity; the J1772 interface is a relatively universal charging interface standard with strong compatibility; and the CHAdeMO interface has certain advantages in charging speed. The setting of the second emergency charging port 3 and the first emergency charging port 2 ensures that the four-way shuttle has a suitable emergency charging path when the power is insufficient in different locations.

[0037] Based on any of the above embodiments, the above-mentioned four-way shuttle vehicle emergency charging structure also includes protective components for protecting the first emergency charging port 2 and the second emergency charging port 3. There are two protective components, which are respectively located on the vehicle body 1 at the first emergency charging port 2 and the second emergency charging port 3.

[0038] One specific embodiment of the above-mentioned protective components is as follows: Figure 3As shown, the protective assembly includes a first rotating shaft 41, a first cover plate 42, and a torsion spring 43. The first rotating shaft 41 is fixedly disposed on one side of the first emergency charging port 2 or the second emergency charging port 3. The first cover plate 42 is disposed on the first emergency charging port 2 or the second emergency charging port 3, and one side of the first cover plate 42 is rotatably disposed on the first rotating shaft 41. The torsion spring 43 is sleeved on the first rotating shaft 41, one end of the torsion spring 43 is fixedly connected to the first rotating shaft 41, and the other end of the torsion spring 43 is fixedly connected to the first cover plate 42.

[0039] Specifically, taking the first emergency charging port 2 as an example in the figure, the installation method of the protective component at the second emergency charging port 3 is the same as that at the first emergency charging port 2, and will not be described further. On the base plate of the vehicle body 1, where the first emergency charging port 2 is located, there is a mounting groove for installing the first cover plate 42 at the first emergency charging port 2. A first rotating shaft 41 is welded into the mounting groove. The axis of the first rotating shaft 41 is parallel to one side of the first emergency charging port 2. One side of the first cover plate 42 is rotatably limited and connected to the first rotating shaft 41. The first cover plate 42 can rotate along the axis of the first rotating shaft 41, thereby opening and closing the first emergency charging port 2. When manually charging the vehicle in an emergency, the first cover plate 42 can be rotated around the first rotating shaft 41 by pulling the handle on its surface, thus exposing the first emergency charging port 2, allowing the vehicle to be charged in an emergency using the charging plug.

[0040] Optionally, to facilitate the active reset of the first cover plate 42, a torsion spring 43 is sleeved on one side of the first rotating shaft 41. One end of the torsion spring 43 is welded to one side of the first cover plate 42, and the other end of the torsion spring 43 is welded to the surface of the first rotating shaft 41. When charging is required, the first cover plate 42 is opened, and the torsion spring 43 is compressed. After charging is completed, the first cover plate 42 is released, the torsion spring 43 returns to its original state, and the first cover plate 42 is automatically closed, thus playing a protective role.

[0041] Furthermore, a sealing gasket is provided on the outer periphery of the first cover plate 42, and the sealing gasket abuts between the first cover plate 42 and the first emergency charging port 2 or the second emergency charging port 3.

[0042] Specifically, a sealing gasket is provided on the outer periphery of the first cover plate 42. The sealing gasket abuts between the first cover plate 42 and the first emergency charging port 2 or the second emergency charging port 3. The sealing gasket can be made of rubber and has good sealing performance to prevent dust, moisture and other substances from entering the emergency charging port.

[0043] Another specific embodiment of the above-mentioned protective component is as follows: Figure 4As shown, the protective assembly includes a second rotating shaft 44, a second cover plate 45, and a driving component. The second rotating shaft 44 is rotatably disposed on one side of the first emergency charging port 2 or the second emergency charging port 3. The second cover plate 45 is disposed on the first emergency charging port 2 or the second emergency charging port 3, and one side of the second cover plate 45 is fixedly connected to the second rotating shaft 44. The driving component is disposed on the vehicle body 1 and is used to drive the second rotating shaft 44 to rotate.

[0044] Specifically, continuing with the example of the first emergency charging port 2, a base plate on the vehicle body 1 with the first emergency charging port 2 has a mounting groove for installing the second cover plate 45 at the location of the first emergency charging port 2. A second rotating shaft 44 is rotatably connected within the mounting groove. The axis of the second rotating shaft 44 is arranged parallel to one side of the first emergency charging port 2. One side of the second cover plate 45 is welded to the second rotating shaft 44, and the second cover plate 45 can rotate with the rotation of the second rotating shaft 44.

[0045] Furthermore, the vehicle body 1 is also equipped with a drive component for rotating the second rotating shaft 44. By controlling the drive component to rotate the second rotating shaft 44, the first emergency charging port 2 can be opened and closed. This exposes the first emergency charging port 2, allowing it to be used with a charging plug for emergency charging of the vehicle.

[0046] Optionally, the driving component includes a rotary motor 46, which is fixedly mounted on the vehicle body 1, and the output shaft of the rotary motor 46 is connected to the second rotating shaft 44 for transmission.

[0047] Specifically, the rotary motor 46 is located inside the vehicle body 1. A drive gear is located at the end of the output shaft of the rotary motor 46, and a driven gear is fixedly mounted on the second rotating shaft. The drive gear and the driven gear are connected by a chain 47. The rotary motor 46 drives the drive gear to rotate, and the chain 47 drives the driven gear, which is connected to the drive gear, to rotate, thereby rotating the second rotating shaft 44 and thus opening and closing the first emergency charging port 2. The drive gear can be directly mounted on the output shaft of the rotary motor 46, or it can be rotatably mounted inside the vehicle body 1 via a bracket and fixedly connected coaxially to the output shaft of the rotary motor 46.

[0048] Furthermore, a sealing gasket is provided on the outer periphery of the second cover plate 45, and the sealing gasket abuts between the second cover plate 45 and the first emergency charging port 2 or the second emergency charging port 3.

[0049] Specifically, a sealing gasket is provided on the outer periphery of the second cover plate 45. The sealing gasket abuts between the second cover plate 45 and the first emergency charging port 2 or the second emergency charging port 3. The sealing gasket can be made of rubber and has good sealing performance to prevent dust, moisture and other substances from entering the emergency charging port.

[0050] The implementation principle of this embodiment is as follows: The emergency charging structure for the four-way shuttle vehicle is equipped with a first emergency charging port 2 and a second emergency charging port 3 on the bottom and side of the vehicle body, respectively, and uses a standardized quick-connect interface. When the four-way shuttle vehicle is low on power at a non-charging location, it can easily be temporarily charged through the emergency charging ports. Simultaneously, the protective components protect the emergency charging ports from dust, moisture, and other corrosion, extending their service life. Two different protective component structures can be selected according to actual needs, improving the applicability and reliability of the emergency charging structure and enhancing the operational efficiency of the warehousing and logistics system.

[0051] This application further discloses a four-way shuttle, including the aforementioned emergency charging structure for a four-way shuttle. The remaining structure of this four-way shuttle is the same as that of existing four-way shuttles, and will not be described again here. This four-way shuttle has the aforementioned emergency charging structure for a four-way shuttle, and therefore also has the beneficial effects of the aforementioned emergency charging structure for a four-way shuttle.

[0052] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
