DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "fixed," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0021] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature and the second feature being in direct contact, or may include the first feature and the second feature being in contact not directly but through another feature therebetween. Moreover, a first feature being "above," "below," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0022] In the description of this embodiment, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of this application.

[0023] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0024] The automatic charging device for the shuttle vehicle of this embodiment can automatically charge and power off the shuttle vehicle, eliminating the need for personnel to manually control the plugging and unplugging of the charger, thereby reducing the risk of electric shock to personnel.

[0025] like Figures 1 to 4 As shown, the automatic charging device for shuttle vehicles in this embodiment primarily comprises a charging unit 1 and an automatic switching mechanism. The charging unit 1 employs the structure of existing chargers and is used to provide electrical energy to the shuttle vehicle. The automatic switching mechanism comprises a bracket 2, a microswitch 3, a charging brush plate 4, an elastic connector 5, and a trigger 6. The bracket 2 is fixedly connected to the charging unit 1; the microswitch 3 and charging brush plate 4 are fixedly mounted on the bracket 2 and are each electrically connected to the charging unit 1. The trigger 6, which is used to activate the microswitch 3, is elastically connected to the bracket 2 via the elastic connector 5.

[0026] With the above structure, when the shuttle vehicle moves to contact the trigger 6 and further pushes the trigger 6, the elastic connector 5 is compressed and drives the trigger 6 to move to contact the transmission element 31 of the micro switch 3. At the same time, the charging brush block on the shuttle vehicle is also connected to the charging brush plate 4 of the charging device. As the elastic connector 5 is further compressed, the trigger 6 moves further toward the micro switch 3 until the micro switch 3 is triggered. The internal circuit of the charging body 1 is closed and the shuttle vehicle begins to charge. When the shuttle vehicle detects that the battery is full, it automatically leaves the current charging position. The pressure on the elastic connector 5 is released. During its reset process, the trigger 6 separates from the micro switch 3, and the internal circuit of the charging body 1 is disconnected to wait for the next charge. During the above process, no human operation is required, which reduces the risk of electric shock and saves labor costs.

[0027] like Figure 2As shown, the bracket 2 of this embodiment includes a base plate 21, a first side plate 22, and a second side plate 23. The first side plate 22 and the second side plate 23 are respectively connected to the base plate 21 and are arranged opposite each other. In other words, the first side plate 22 and the second side plate 23 are arranged parallel to each other on either side of the base plate 21. The charging brush plate 4 is fixed to the first side plate 22. Preferably, the height of the second side plate 23 can be set to be smaller to avoid affecting the connection between the charging brush block on the shuttle and the charging brush plate 4 of the charging device.

[0028] like Figure 3 and Figure 4 As shown, the elastic connecting member 5 of this embodiment includes a guide rod 51, a compression spring 52 and a slider 53. One end of the guide rod 51 is connected to the first side plate 22 of the bracket 2, and the other end of the guide rod 51 is connected to the second side plate 23 of the bracket 2. The compression spring 52 and the slider 53 are both mounted on the guide rod 51, and the slider 53 is located at one end of the compression spring 52 close to the second side plate 23. The trigger 6 is connected to the slider 53. When the body of the shuttle pushes the trigger 6, the compression spring 52 is compressed and drives the slider 53 and the trigger 6 to move toward the first side plate 22, so that the trigger 6 presses the micro switch 3, and the charging brush block on the body is connected to the charging brush plate 4 of the device.

[0029] Furthermore, the charging device of this embodiment also includes a movable frame 7 connected to the slider 53. The movable frame 7 is in the shape of a U-shaped U-shaped frame and is used to abut against the body of the shuttle vehicle. When not in the charging state (or the shuttle vehicle has not yet contacted the movable frame 7), the distance between the movable frame 7 and the first side plate 22 is greater than the distance between the charging brush plate 4 and the first side plate 22; when in the charging state, as the compression spring 52 is compressed, the movable frame 7 moves to a distance between the movable frame 7 and the first side plate 22 that is less than the distance between the charging brush plate 4 and the first side plate 22. In other words, during the movement of the movable frame 7, the charging brush plate 4 can pass through the movable frame 7 to contact the charging brush block of the shuttle vehicle, or exit the movable frame 7 after separating from the charging brush block.

[0030] To enhance the stability of the connection between the movable frame 7 and the bracket 2 and the stability of the movement of the movable frame 7, the elastic connector 5 of this embodiment may include multiple guide rods 51, each of which is fitted with a compression spring 52 and a slider 53. The movable frame 7 is connected to the multiple sliders 53. The actuator 6 is connected to the slider 53 closest to the transmission element 31 of the micro switch 3.

[0031] like Figure 4As shown, the trigger 6 of this embodiment includes a first wall 61 and a second wall 62 on the side facing the microswitch 3. A slanted wall 63 is disposed between the first and second walls 61, 62, serving as a transition between them. Preferably, the angled wall 63 is rounded where it meets the first wall 61, and the angled wall 63 is also rounded where it meets the second wall 62. A gap exists between the first wall 61 and the microswitch 3, while the second wall 62 is used to actuate the microswitch 3. Specifically, in the non-charging state, the first wall 61 is positioned adjacent to the transmission element 31 of the microswitch 3, but the two do not contact each other. As the trigger 6 is pushed by the shuttle, the slanted wall 63 and the second wall 62 move sequentially to the microswitch 3. When the second wall 62 contacts the transmission element 31 of the microswitch 3, the microswitch 3 is actuated.

[0032] To sum up, the working process of the automatic charging device for shuttle vehicles using the present embodiment is as follows: when the battery power of the shuttle vehicle is less than 20%, the currently transported goods will be placed on the designated cargo position, and then automatically return to the charging device on the shelf section at high speed; when the shuttle vehicle reaches the charging position, it slowly moves forward to push the movable frame 7 of the device until the charging brush block on the vehicle body is connected with the charging brush plate 4 on the device, and the trigger 6 presses the micro switch 3, and the charging device charges the shuttle vehicle; when the shuttle vehicle detects that the battery is fully charged, it automatically leaves the current charging position, the trigger 6 separates from the micro switch 3, resets, and waits for the next charging.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope.
