Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a floating docking device for a charging pile. Background Art

[0002] AGV (Automated Guided Vehicle) is an unmanned automated vehicle that can accurately follow the prescribed path and complete a series of tasks after reaching the designated location. The control computer can decide whether to go to the charging area for automatic charging based on the AGV's own power.

[0003] However, due to environmental errors, assembly errors, navigation positioning errors and other reasons, there will be a certain deviation between the charging port of the AGV and the charging head of the charging pile during automatic docking. Therefore, a floating docking device is usually installed at the charging head. The floating docking device can automatically reset after the charging port is separated from the charging head to reduce or offset the docking deviation and facilitate the next docking and charging.

[0004] The existing floating docking device is provided with a floating plate, and the charging head is connected to the floating plate; in order to ensure the stability of the floating plate's reset, a pair of reset springs are usually provided on both sides of the floating plate in a one-to-one correspondence, so as to realize automatic reset of the charging head after the charging port is separated. A pair of reset springs act on a floating plate at the same time. When the floating plate moves in a floating direction, the closer it is to the end of the reset stroke of the floating plate, the elastic force of the pair of reset springs will offset each other, and the force applied to the floating plate will be smaller. Therefore, it is difficult to reset the floating plate to the designed position with high precision, making it difficult to accurately reset the floating plate after the AGV is separated. After charging is completed, the position of the charging head deviates from the designed reset position, which in turn affects the next docking of the AGV and the charging pile. At the least, it is difficult to dock and charge, and at worst, the charging port and the charging head are damaged. Utility Model Content

If the specific posture changes, the directional indication will also change accordingly.

[0052] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0053] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] First embodiment:

[0055] See also Figure 1 and Figure 2 The utility model provides a floating docking device for a charging pile, and the floating docking device includes a mounting plate 1, a transverse floating plate 2, a transverse separation plate 3, a first transverse return spring 4 and a second transverse return spring 5; a transverse slide rail 11 is arranged on the mounting plate 1; the transverse floating plate 2 and the transverse separation plate 3 are both connected to the transverse slide rail 11 in a transverse sliding manner; one end of the first transverse return spring 4 is connected to the transverse floating plate 2, and the other end is connected to the transverse separation plate 3; the transverse separation plate 3 is provided with a slide bar 31; a slide groove 12 is provided on the mounting plate 1; the slide bar 31 is connected to the slide groove 12 in a transverse sliding manner; one end of the second transverse return spring 5 is connected to the mounting plate 1, and the other end is connected to the free end of the slide bar 31. Among them, the transverse direction is the sliding direction of the transverse slide rail 11, that is, the left and right direction. The transverse slide rail 11 can be a guide rail slider module, or a guide shaft slider module.

[0056] It should be noted that the existing floating plate usually slides on the slide bar, and the slide bar is provided with a reset spring. A pair of reset springs are arranged one by one on both sides of the floating plate to achieve buffering and reset of the floating plate. Due to environmental errors, assembly errors, navigation positioning errors and other reasons, there will always be a certain deviation between the charging head 20 and the charging port when docking; and the way the reset spring is sleeved on the slide bar will produce a friction wheel between the reset spring and the slide bar, further reducing the reset accuracy of the floating plate. In addition, a pair of reset springs act on a floating plate at the same time, such as two compressed reset springs. When the floating plate moves in a floating direction, the closer it is to the end of the reset stroke of the floating plate (when it is about to reset), the elastic force applied by the pair of reset springs to the floating plate will offset each other, and the force applied to the floating plate will be smaller, and the force is not enough to continue to push the floating plate to reset. The above reasons cause the actual position of the charging head 20 to deviate from the designed reset position, affecting the next docking of the AGV and the charging pile.

[0057] Compared to the installation method of arranging a pair of return springs one by one on both sides of the floating plate, the floating docking device of the utility model makes the first transverse return spring 4 responsible for the docking buffering during the movement of the transverse floating plate 2 to the right, and the rebound return to the left; and makes the second transverse return spring 5 responsible for the docking buffering during the movement of the transverse floating plate 2 to the left, and the rebound return to the right.

[0058] The charging head 20 is installed on the transverse floating plate 2. When the AGV pushes the transverse floating plate 2 to move in a single transverse direction, only one of the first transverse return spring 4 and the second transverse return spring 5 works; similarly, only one transverse return spring works during resetting. By independently setting the first transverse return spring 4 and the second transverse return spring 5, a transverse return spring can only be reset in a single transverse direction. The setting of a pair of transverse return springs not only ensures the stability of the transverse floating plate 2 during resetting, but also cuts off the joint force of the pair of transverse return springs on the transverse floating plate 2 when moving in a single transverse direction, thereby achieving high-precision resetting of the transverse floating plate 2 in the transverse direction, eliminating or reducing the dimensional deviation of the transverse floating plate 2 from the designed resetting position, and facilitating the next docking and charging of the AGV and the charging pile.

[0059] Both the transverse floating plate 2 and the transverse separation plate 3 are connected to the transverse slide rail 11 in a transverse sliding manner. The transverse floating plate 2 can push the transverse separation plate 3 to move, and the transverse separation plate 3 can also push the transverse floating plate 2 to move. One end of the first transverse return spring 4 is connected to the transverse floating plate 2, and the other end is connected to the transverse separation plate 3. When the AGV pushes the transverse floating plate 2 to move to the left, the transverse floating plate 2 pushes the transverse separation plate 3 to move synchronously, and the second transverse return spring 5 extends to achieve buffering of the transverse floating plate 2; when the AGV is separated from the charging head 20, the second transverse return spring 5 retracts and drives the transverse separation plate 3 to move to the right, and the transverse separation plate 3 then pushes the transverse floating plate 2 to reset. During the entire process from docking to separation between the AGV and the charging head 20, the first transverse return spring 4 does not work.

[0060] The slide bar 31 is connected to the slide slot 12 in a lateral sliding manner. The slide slot 12 not only improves the stability of the lateral separation plate 3 during the lateral sliding process, but also limits the maximum sliding path of the lateral separation plate 3 in the lateral direction. One end of the second lateral return spring 5 is connected to the mounting plate 1, and the other end is connected to the free end of the slide bar 31. When the AGV pushes the lateral floating plate 2 to move to the right, the slide bar 31 is engaged with the rightmost end of the slide slot 12, so that the left end of the first lateral return spring 4 becomes a fixed end, and then the right end of the first lateral return spring 4 is stably extended and retracted to achieve buffering of the lateral floating plate 2; when the AGV is separated from the charging head 20, the first lateral return spring 4 retracts until the lateral floating plate 2 is reset. During the entire process from docking to separation between the AGV and the charging head 20, the second lateral return spring 5 does not work.

[0061] Second embodiment:

[0062] like Figure 3 and Figure 4As shown, on the basis of the first embodiment, the floating docking device further includes a vertical floating plate 6, a vertical separation plate 7, a first vertical return spring 8 and a second vertical return spring 9; a vertical slide rail 21 is provided on the horizontal floating plate 2; the vertical floating plate 6 and the vertical separation plate 7 are both connected to the vertical slide rail 21 in a vertical sliding manner; one end of the first vertical return spring 8 is connected to the vertical floating plate 6, and the other end is connected to the vertical separation plate 7; a limit plate 22 is provided on the horizontal floating plate 2; the limit plate 22 is located at the bottom end of the vertical separation plate 7 so as to limit the vertical movement of the vertical separation plate 7; one end of the second vertical return spring 9 is connected to the horizontal floating plate 2, and the other end is connected to the vertical separation plate 7. In this embodiment, the charging head 20 is connected to the vertical floating plate 6 through an adapter plate 201. The vertical direction is the sliding direction of the vertical slide rail 21, that is, the up and down direction. Similarly, the vertical floating plate 6 is set analogously to the horizontal floating plate 2, and the vertical separation plate 7 is set analogously to the horizontal separation plate 3.

[0063] Specifically, the charging head 20 is arranged on the vertical floating plate 6. When the AGV pushes the vertical floating plate 6 to move downward, the limit plate 22 blocks the vertical separation plate 7 from moving downward. The upper end of the first vertical return spring 8 is a fixed end, so that the lower end of the first vertical return spring 8 stably extends with the downward movement of the vertical floating plate 6, thereby achieving buffering of the vertical floating plate 6. When the AGV is separated from the charging head 20, the first vertical return spring 8 retracts until the vertical floating plate 6 is reset. During the entire process from docking to separation between the AGV and the charging head 20, the second vertical return spring 9 does not work.

[0064] When the AGV pushes the vertical floating plate 6 to move upward, the vertical floating plate 6 pushes the vertical separation plate 7 to move upward synchronously, and the lower end of the second vertical return spring 9 is fixed on the horizontal floating plate 2 as a fixed end, and the upper end of the second vertical return spring 9 stably extends with the upward movement of the vertical separation plate 7 to achieve buffering of the vertical floating plate 6; when the AGV is separated from the charging head 20, the second vertical return spring 9 retracts until the vertical floating plate 6 is reset. During the entire process from docking to separation between the AGV and the charging head 20, the first vertical return spring 8 does not work.

[0065] The second embodiment is based on the first embodiment, and adds a vertical resetting mechanism for the vertical floating plate 6, so that the charging head 20 can perform both horizontal buffering and resetting, and vertical buffering and resetting, further reducing or offsetting the dimensional deviation of the docking between the charging port and the charging head 20, meeting the charging requirements, and effectively ensuring the high-precision resetting of the floating docking device under different working conditions (AGV in different positions).

[0066] Furthermore, the floating docking device also includes a base plate 10 and a longitudinal return spring 101; a longitudinal slide rail 102 is provided on the base plate 10; the mounting plate 1 is connected to the longitudinal slide rail 102 in a longitudinal sliding manner; one end of the longitudinal return spring 101 is connected to the base plate 10, and the other end is connected to the mounting plate 1. The longitudinal direction is the sliding direction of the longitudinal slide rail 102, that is, the front-to-back direction. When the AGV pushes the vertical floating plate 6 to move backward, the mounting plate 1 moves backward synchronously, and the longitudinal return spring 101 stretches for buffering; when the AGV is separated from the charging head 20, the longitudinal return spring 101 retracts until the mounting plate 1 is reset, that is, the vertical floating plate 6 and the charging head 20 are reset, so that the floating docking device can reset the charging head 20 in the longitudinal direction, further improving the high-precision reset of the floating docking device under different working conditions.

[0067] Secondly, a pair of longitudinal return springs 101 are arranged on both sides of the mounting plate 1 in a one-to-one correspondence, which further improves the longitudinal movement stability of the mounting plate 1 and improves the buffering performance and return performance of the mounting plate 1.

[0068] In addition, a pair of baffles 13 are provided on both sides of the mounting plate 1 in a one-to-one correspondence; the pair of baffles 13 are connected to both ends of the transverse slide rail 11 in a one-to-one correspondence. The baffles 13 can limit the transverse movement of the transverse floating plate 2 or the transverse separation plate 3, effectively preventing the transverse floating plate 2 or the transverse separation plate 3 from sliding off the mounting plate 1, and the structure is simple and practical.

[0069] Furthermore, hook blocks 23 are provided on the transverse floating plate 2, the transverse separation plate 3 and the mounting plate 1; a hook groove is provided in the hook block 23; the two ends of the first transverse return spring 4 are correspondingly engaged with a pair of hook grooves; the two ends of the second transverse return spring 5 are correspondingly engaged with a pair of hook grooves. The hook groove is a U-shaped groove or a circular groove, which can be set accordingly according to the installation requirements. The setting of the hook block 23 and the hook groove makes the installation method of each return spring flexible, and the fixing point of the return spring is no longer limited to being set between the side plates of the two plates, but can also be set on the end surfaces of the two plates, such as the first transverse return spring 4; and it is easy to disassemble and replace the return spring after it is damaged.

[0070] Secondly, the first transverse return spring 4 and the second transverse return spring 5 are both tension springs or compression springs. Similarly, the longitudinal return spring 101, the first vertical return spring 8 and the second vertical return spring 9 can also be tension springs or compression springs. The type of spring can be flexibly selected to meet the linear expansion and contraction requirements and elasticity requirements.

[0071] In addition, when the transverse floating plate 2 moves in the transverse direction, the transverse floating plate 2 can abut against the transverse separation plate 3 in a surface-to-surface manner. The surface-to-surface abutment method can effectively improve the stability of the transverse floating plate 2 and the transverse separation plate 3 when they push each other, and further improve the reset accuracy of the charging head 20. Optionally, the transverse floating plate 2 and the transverse separation plate 3 have the same thickness.

[0072] It should be understood that the above description of the specific embodiments of the utility model is only for illustrating the technical route and features of the utility model, and its purpose is to enable those skilled in the art to understand the content of the utility model and implement it accordingly, but the utility model is not limited to the above specific implementation methods. All changes or modifications made within the scope of the claims of the utility model should be included in the protection scope of the utility model.
