[0033] Please refer to Figure 1-Figure 8The utility model provides an automatic gun retracting and releasing device for a charging pile, comprising a machine housing 1, a gun rack 3 and a driving assembly. The machine housing 1 is provided with a telescopic opening 10 communicated with its own inner cavity; the gun rack 3 is used to hang or insert a charging gun 4, that is, the charging gun 4 is hung, fixed or inserted and locked on the gun rack 3; the driving assembly comprises a primary guide 53, a secondary guide 54 and a driving unit, the opposite ends of the primary guide 53 are respectively fixedly connected with two first fixing plates 5, the first fixing plate 5 is fixed in the machine housing 1, the secondary guide 54 is slidably connected to the primary guide 53, and the secondary guide 54 can pass through the telescopic opening 10, and the secondary guide 54 is also connected and fixed to the gun rack 3. Specifically: the primary guide member 53 and the secondary guide member 54 are both guide rails, the extension direction of the secondary guide member 54 is the same as the extension direction of the primary guide member 53, one end of the secondary guide member 54 is slidably connected to the primary guide member 53, and the other end of the secondary guide member 54 is fixedly connected to the gun frame 3; a driving unit is arranged in the housing 1, and the driving unit is used to drive the secondary guide member 54 to slide along the primary guide member 53, so that the gun frame 3 can extend out of the housing 1 or retract into the housing 1 through the telescopic opening 10.

[0034] When the automatic gun retracting device of the charging pile of the utility model is in use, if the charging gun 4 is charging the device, the gun rack 3 can also be automatically retracted into the machine housing 1, which overcomes the defect of the automatic gun retracting device of the existing charging pile when the charging gun 4 is charging the device, that the gun rack 3 cannot be automatically retracted into the machine housing 1. Specifically, how to automatically retract the gun rack 3 into the machine housing 1 is described as follows: Since the primary guide 53 is fixed in the machine housing 1, the secondary guide 54 is slidably connected with the primary guide 53, and the secondary guide 54 can pass through the telescopic opening 10, when the gun rack 3 needs to be retracted into the machine housing 1, the secondary guide 54 is driven by the driving unit to slide along the primary guide 53, so that the gun rack 3 can be extended from the position of the telescopic opening 10 and retracted into the machine housing 1.

[0035] Of course, the automatic charging pile gun retracting device of the utility model also includes a winding mechanism arranged in the housing 1, referring to Figure 3, the winding mechanism is used to retract the gun wire of the charging gun 4. In addition, a power supply module electrically connected to the gun wire of the charging gun 4 is also provided in the housing 1. The power supply module supplies power to the charging gun 4 in the housing, which belongs to the existing technology of mobile charging piles and will not be explained here. After the charging gun 4 has charged the device (such as a new energy vehicle or a robot), the user plugs or hangs the charging gun 4 on the gun rack 3. Therefore, when the charging gun 4 and the gun rack 3 need to be stored in the housing 1 at the same time, the driving unit and the winding mechanism are started at the same time. The driving unit drives the secondary guide 54 to slide along the primary guide 53, driving the gun rack 3 to extend from the position of the telescopic opening 10 and retract into the housing 1. At the same time, the winding mechanism reels the gun wire of the charging gun 4, so that the charging gun 4 and the gun rack 3 can be stored in the housing 1 at the same time.

[0036] It should be noted here that the wire winding mechanism uses an existing wire winding mechanism, and since the wire winding mechanism is used to retract and release the gun wire of the charging gun 4, it belongs to the existing technology in the field of mobile charging piles, so it is not described here.

[0037] In one embodiment, referring to Figure 1 , Figure 2 A sealing plate 2 for sealing the telescopic opening 10 is hinged on the housing 1, and the sealing plate 2 is linked with the gun rack 3. That is, it can be understood that when the gun rack 3 is retracted from the position of the telescopic opening 10 into the housing 1, the gun rack 3 is linked with the sealing plate 2 to cover the telescopic opening 10, thereby improving the protection performance and overall appearance performance of the automatic gun retracting and releasing device of the charging pile.

[0038] In one embodiment, the secondary guide 54 is connected to the gun rack 3 via a connecting plate 55, so that the contact area between the gun rack 3 and the secondary guide 54 can be increased, thereby facilitating the connection and fixation between the gun rack 3 and the secondary guide 54. In addition, a linkage chain 550 or a linkage rope is also fixed to the connecting plate 55, that is, it can be understood that the first end of the linkage chain 550 or the linkage rope is connected and fixed to the gun rack 3 via the connecting plate 55, and the second end of the linkage chain 550 or the linkage rope is connected and fixed to the sealing plate 2. Specifically, referring to Figure 1 , Figure 7 and Figure 8 A connecting portion 20 is fixed on the inner surface of the sealing plate 2, and the connecting portion 20 is welded and fixed to the sealing plate 2. When the sealing plate 2 blocks the telescopic opening 10, the connecting portion 20 is located in the housing 1, and the second end of the linkage chain 550 or the linkage rope is connected and fixed to the connecting portion 20. Figure 1 The dotted line in shows the connection position between the linkage chain 550 and the connection part 20.

[0039] Here is a detailed explanation of how the closing plate 2 is linked to the gun rack 3: since the closing plate 2 is hinged to a side wall inside the telescopic opening 10 by a hinge, the gun rack 3 is fixed to the connecting plate 55, and the connecting plate 55 is fixed to the secondary guide member 54, and the secondary guide member 54 can slide along the primary guide member 53. Therefore, when the connecting plate 55 rises under the drive of the driving unit, after the gun rack 3 is completely retracted into the machine body 1, the connecting plate 55 continues to be driven by the driving unit to move upward for a distance, so that the linkage chain 550 or linkage rope on the connecting plate 55 drives the closing plate 2 to cover the telescopic opening 10.

[0040] Of course, when the charging gun 4 is charging the device (new energy vehicle or robot), the gun holder 3 is retracted into the housing 1 and the sealing plate 2 is linked to cover the telescopic opening 10. In order to avoid interference between the sealing plate 2 and the gun line of the charging gun 4, an avoidance through hole for avoiding the gun line can be opened on the sealing plate 2; or, the sealing plate 2 does not completely close the telescopic opening 10, so that an avoidance opening 11 for avoiding the gun line is left between the sealing plate 2 and the telescopic opening 10.

[0041] In one embodiment, referring to Figure 3 , Figure 4 The driving unit includes a driving motor 51, a cable reel 52 and a pull rope 520. The cable reel 52 is rotatably disposed in the machine housing 1. One end of the pull rope 520 is fixed on the cable reel 52, and the other end of the pull rope 520 is a free end. The pull rope 520 is wound around the cable reel 52, and the free end of the pull rope 520 is drivingly connected to the gun rack 3. In addition, the driving motor 51 is fixed in the machine housing. Specifically, the driving motor 51 is fixed in the machine housing 1 through the second fixing plate 50. The output shaft of the driving motor 51 is drivingly connected to the cable reel 52. In this way, the driving motor 51 drives the cable reel 52 to rotate, which can drive the pull rope 520 to drive the gun rack 3 to extend from the position of the telescopic opening 10 outside the machine housing 1 or retract into the machine housing 1. Among them, Figure 4 The dotted line in FIG. 5 represents the connection position between the pull rope 520 and the connecting plate 55 .

[0042] Of course, in other embodiments, the driving unit may also be a linear driving module or an electric drive or a ball screw mechanism, which can also drive the gun rack 3 to extend out of the housing 1 or retract into the housing 1 from the telescopic opening 10, which is not limited here. Therefore, for those skilled in the art, by reasonably changing the structure of the driving unit, it should also fall within the protection scope of the present utility model.

[0043] In one embodiment, referring to Figure 5, the gun rack 3 and the connecting plate 55 are arranged at an angle, and the angle between the gun rack 3 and the connecting plate 55 is 35-40°. The angle between the gun rack 3 and the connecting plate 55 of this embodiment is the gun removal angle, and the gun removal angle is 35°. At this angle, the gun rack 3 can facilitate the removal and placement of the charging gun 4. Of course, in other embodiments, the gun removal angle can also be 40° or 38°, which is not limited here.

[0044] In one embodiment, referring to Figure 4 , Figure 6 , the gun rack 3 is rotatably arranged on the connecting plate 55 through the rotating shaft 6, and the rotating shaft 6 is rotatably arranged on the connecting plate 55 through the bearing 61. Of course, the rotating shaft 6 is parallel to the machine housing 1, so that the gun rack 3 can swing to form a gun-taking angle between the connecting plate 55; in addition, a limiting structure is provided between the connecting plate 55 and the gun rack 3, and the limiting structure is used to limit the gun rack 3 to be locked at the gun-taking angle to prevent the gun line from swinging during the movement. Specifically, it can be understood that after the charging gun 4 is charged and fixed on the gun rack 3, when the charging gun 4 and the gun rack 3 need to be retracted into the machine housing 1, the winding mechanism will reel in the gun line of the charging gun 4. Therefore, the gun rack 3 is limited to be locked at the gun-taking angle by the limiting structure, which can prevent the gun line from swinging during the movement.

[0045] In one embodiment, referring to Figure 4 , Figure 5 The limiting structure includes a magnetic member 30 fixed on the gun rack 3, the connecting plate 55 is a metal plate, a limiting portion 551 magnetically attracted to the magnetic member 30 is fixed on the connecting plate 55, the limiting portion 551 is welded and fixed to the connecting plate 55, and the magnetic member 30 is magnetically fixed to the limiting portion 551 on the connecting plate 55. That is, it can be understood that when the gun rack 3 rotates to form a gun-taking angle with the connecting plate 55, the magnetic member 30 on the gun rack 3 is magnetically fixed to the limiting portion 551 on the connecting plate 55, thereby locking the gun rack 3 at the gun-taking angle.

[0046] Of course, in other embodiments, the limiting structure may also use Velcro or a snap-on structure, etc., which is not limited here. It only needs to be able to lock the gun rack 3 at the position of the gun taking angle.

[0047] In one embodiment, referring to Figure 6 A torsion spring 60 is sleeved on the rotating shaft 6, and the opposite ends of the torsion spring 60 are respectively connected and fixed to the connecting plate 55 and the gun frame 3, and the torsion spring 60 is used to reset the gun frame 3 to a vertical state with respect to the machine housing 1. That is, it can be understood that after the limit structure is unlocked, the gun frame 3 is reset to a vertical state with respect to the machine housing 1 under the action of the torsion spring 60, so that when the gun frame 3 rises and retracts into the machine housing 1, it can avoid that the gun frame 3 occupies too much horizontal position of the telescopic opening 10.

[0048] The working principle of this utility model:

[0049] Gun releasing process: the hoisting mechanism and the driving unit work at the same time, the gun rack 3 starts to move downward, and the lower sealing plate 2 also opens downward at the same time. When the gun rack 3 descends and extends out of the telescopic opening 10, since the charging gun 4 is fixed on the gun rack 3, the charging gun 4 descends with the gun rack 3, and the gun line also descends with the charging gun 4. Under the action of the rotating shaft 6 and the torsion spring 60, the gun rack 3 rotates to the extreme position (gun taking angle) and is locked by the limiting structure. When the gun line is released, the user takes out the charging gun 4 from the gun rack 3, and the micro-motion sensor on the gun rack 3 detects that the gun taking is completed. The driving unit drives the gun rack 3 to retract into the machine body 1, and at the same time drives the sealing plate 2 to close the telescopic opening 10.

[0050] Gun collection process: After the user has used the charging gun 4, he places and fixes it on the gun rack 3. The micro-motion sensor on the gun rack 3 detects that the charging gun 4 is placed in place. At this time, the hoisting mechanism winds the gun line, driving the limit structure to unlock. At this time, the gun rack 3 is reset to a vertical state with the machine housing 1 under the action of the torsion spring 60. At the same time, the driving unit drives the gun rack 3 to rise and retract into the machine housing 1.

[0051] It should be noted that since the gun rack 3 is locked at the gun removal angle by magnetic attraction, when the charging gun 4 is hung and fixed on the gun rack 3, the hoisting mechanism winds the gun line and pulls the charging gun 4. The pulling force is greater than the magnetic attraction force, which can cause the magnetic attraction part 30 on the gun rack 3 to disengage from the connecting plate 55, thereby achieving the purpose of unlocking the limit structure.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
