[0035] Referring to Figure 1 and Figure 2 , some embodiments of the present application provide a charging pile 100, which comprises a housing 10, a cover plate 20, a gun rack 30 and a charging gun 40. The housing 10 is provided with a receiving cavity at one end opening 11 and inwardly recessed; the cover plate 20 is movably arranged at the opening 11 and can expose or shield the opening 11; the charging gun 40 is installed on the gun rack 30, and the charging gun 40 can be switched between a use state and an idle state. In the use state, the opening 11 is in an exposed state, and the charging gun 40 is moved out of the receiving cavity from the opening 11; in the idle state, the charging gun 40 is located in the receiving cavity, and the cover plate 20 shields the opening 11.

[0036] It can be understood that the gun rack 30 is used to place the charging gun 40. In the process of moving the charging gun 40 out of the receiving cavity, the gun rack 30 is moved out of the receiving cavity together with the charging gun 40. After the charging gun 40 is not used, the charging gun 40 is placed on the gun rack 30, and the gun rack 30 is moved into the receiving cavity together with the charging gun 40.

[0037] The working principle of the charging pile 100 will be described in detail below.

[0038] As shown in Figure 1 , before use, the charging gun 40 is installed on the gun rack 30, and both of them are located in the receiving cavity of the housing 10. At this time, the charging gun 40 is in an idle state, and the cover plate 20 shields the opening 11 of the housing 10. When the charging gun 40 needs to be used, the cover plate 20 moves relative to the housing 10 and exposes the opening 11. The gun rack 30 carries the charging gun 40 to move in the direction close to the opening 11, and when the charging gun 40 and the gun rack 30 are all moved out of the receiving cavity through the opening 11, the charging gun 40 is switched from the idle state to the use state (as shown in Figure 2 ). At this time, the user can take the charging gun 40 off the gun rack 30 and use the charging gun 40 to charge the vehicle.

[0039] After the charging gun 40 is used, the charging gun 40 is placed on the gun rack 30. The gun rack 30 can carry the charging gun 40 to move towards the opening 11, until the gun rack 30 and the charging gun 40 are completely moved into the accommodating cavity, and the charging gun 40 is switched from the use state to the idle state. At this time, the cover plate 20 is moved again relative to the shell 10 and covers the opening 11.

[0040] In summary, the gun rack 30 can carry the charging gun 40 to move out of or into the accommodating cavity, so as to switch the charging gun 40 between different states. When the charging gun 40 is not used, the gun rack 30 and the charging gun 40 are completely located in the accommodating cavity, and the shell 10 can protect the two, so as to reduce the probability that the gun rack 30 and the charging gun 40 collide with external components and are damaged when they are idle. In addition, compared with the gun rack 30 being always exposed to the external environment, the appearance of the charging pile 100 is also beautified.

[0041] Specifically, in some embodiments, the cover plate 20 is linked with the gun rack 30, the cover plate 20 is deflected towards the direction of exposing the opening 11 when the gun rack 30 moves out of the accommodating cavity, and the cover plate 20 is deflected towards the direction of covering the opening 11 when the gun rack 30 moves into the accommodating cavity.

[0042] Exemplarily, the cover plate 20 is installed on the opening 11 in a rotating manner. The cover plate 20 and the gun rack 30 can be connected through a connecting rod or the like, but are not limited to this.

[0043] When the gun rack 30 starts to move towards the opening 11, at this time, the cover plate 20 is deflected relative to the shell 10 under the driving of the gun rack 30 and gradually exposes the opening 11. Moreover, as the moving time of the gun rack 30 increases, the degree of exposure of the opening 11 increases, and finally the opening 11 can be passed through by the gun rack 30 and the charging gun 40. When the gun rack 30 moves to the preset position and stops moving, the cover plate 20 also stops moving.

[0044] When the gun rack 30 located outside the accommodating cavity starts to move towards the opening 11, the cover plate 20 also starts to move. Until the gun rack 30 and the charging gun 40 are completely moved into the accommodating cavity, the cover plate 20 also covers the opening 11.

[0045] In this way, by setting the gun rack 30 and the cover plate 20 in a linkage manner, it is not necessary to manually open and close the cover plate 20, and the automation degree of the charging pile 100 is better realized.

[0046] More specifically, please refer to Figures 3 to 5 In some embodiments, the charging pile 100 further comprises a first driving member 50, a first transmission member 60 and a second transmission member 70, the first transmission member 60 and the second transmission member 70 are connected with the first driving member 50 and move synchronously, the first transmission member 60 is further connected with the gun rack 30, and the second transmission member 70 is further connected with the cover plate 20.

[0047] The first driving member 50 is installed in the accommodating cavity, and can be but not limited to a winch or the like. Assuming that the first driving member 50 is a winch, the first transmission member 60 can include a first part and a second part that are slidingly connected, the first part is fixedly installed on the cavity wall of the accommodating cavity, one end of the second part is connected with the winch, and the other end is provided with the gun rack 30. The second transmission member 70 can be a rope, one end of which is connected with the winch, and the other end is connected with the cover plate 20.

[0048] When the winch is running, it can drive the second part and the second transmission member 70 to move at the same time, so that the second part can move along a preset path relative to the first part to drive the gun rack 30 to move, and the second transmission member 70 can also drive the cover plate 20 to deflect relative to the shell 10.

[0049] The above arrangement simplifies the linkage mode between the gun rack 30 and the cover plate 20, and can improve the synchronization frequency between the gun rack 30 and the cover plate 20.

[0050] As shown in Figure 4 some embodiments, the first transmission member 60 and the gun rack 30 are rotationally connected, and a resilient member 31 is further arranged between the first transmission member 60 and the gun rack 30. When the gun rack 30 is located in the accommodating cavity, the cover plate 20 pushes the gun rack 30, and the resilient member 31 is compressed and deformed; when the gun rack 30 is located outside the accommodating cavity, the gun rack 30 deflects relative to the transmission member.

[0051] For example, the resilient member 31 can be a torsion spring. When an external force is applied to the gun rack 30, because the gun rack 30 and the first transmission member 60 are rotationally connected, the gun rack 30 can rotate relative to the first transmission member 60. As shown in Figure 6 When the gun rack 30 carrying the charging gun 40 moves into the accommodating cavity, because the space of the accommodating cavity is limited, the cover plate 20 can push the gun rack 30, the gun rack 30 can rotate relative to the first transmission member 60, and the torsion spring is twisted, so that the torsion spring has a certain deformation force, and the gun rack 30 and the charging gun 40 rotate, and then the two can completely enter the accommodating cavity and occupy a smaller space.

[0052] When the gun rack 30 carrying the charging gun 40 moves out of the accommodating cavity, the cover plate 20 no longer applies an external force to the gun rack 30, and the gun rack 30 rotates relative to the first transmission member 60 under the action of the deformation force of the torsion spring. The gun rack 30 can be rotated to a preset position to facilitate the user to take the charging gun 40 from the gun rack 30 for charging.

[0053] In this way, not only the space occupied by the gun rack 30 and the charging gun 40 in the accommodating cavity is reduced, but also the gun rack 30 can be adjusted to a position convenient for the user to take the charging gun 40 when the gun rack 30 moves out of the accommodating cavity.

[0054] Further, please refer to Figure 5In some embodiments, the gun mount 30 further includes a first positioning part (not shown in the figure), and the first transmission member 60 includes a second positioning part 61. When the gun mount 30 is located outside the receiving cavity, the first positioning part and the second positioning part 61 are connected.

[0055] The first positioning part and the second positioning part 61 can be configured as magnetically attracted components. During the process of the gun holder 30 moving out of the receiving cavity, the gun holder 30 deflects under the elastic restoring force of the torsion spring. The first positioning part on the gun holder 30 gradually approaches the second positioning component of the first transmission component 60. The first positioning component and the second positioning component are connected under the action of magnetic attraction, thereby limiting the gun holder 30 to a position that is convenient for picking up the charging gun 40 (for example, the gun holder 30 is deflected at a 35° angle). This not only reduces the probability of the gun holder 30 shaking significantly, but also reduces the probability of the charging gun 40's cable shaking significantly.

[0056] like Figure 7 As shown, in some embodiments, the charging pile 100 further includes a winding and unwinding assembly 80, which is used to wind up and unwind the charging gun cable 40. When the first driving member 50 is running, the winding and unwinding assembly 80 starts to unwind synchronously.

[0057] The take-up and unwind assembly 80 is located within the receiving cavity and can operate synchronously with the first drive member 50. This reduces the probability that the charging gun 40 will be pulled off the gun holder 30 due to the charging cable being too short because the start-up time of the take-up and unwind assembly 80 is later than that of the first drive member 50, thereby improving the stability of the charging gun 40 mounted on the gun holder 30.

[0058] Furthermore, in some embodiments, the gun holder 30 includes a detector (not shown in the figure), which is electrically connected to the first drive 50 and the take-up / unwind assembly 80. The detector operates after the charging gun 40 is in use. When the detector detects that the charging gun 40 is in contact with the gun holder 30, the first drive 50 and the take-up / unwind assembly 80 operate synchronously, the gun holder 30 moves into the receiving cavity, and the take-up / unwind assembly 80 winds up the gun cable.

[0059] The detector may be, but is not limited to, a micro-motion sensor, and is configured to operate only when the charging gun 40 is in use. In other words, the detector will not operate when the gun holder 30 is first removed from the receiving cavity.

[0060] The detector only starts operating after the user removes the charging gun 40 from the gun holder 30. After the user finishes use and places the charging gun 40 back into the gun holder 30, the detector, upon detecting that the charging gun 40 has been properly positioned, sends signals to the first drive unit 50 and the take-up / unwind assembly 80. The first drive unit 50 then drives the gun holder 30 to move into the receiving cavity, and the take-up / unwind assembly 80 begins to wind up the charging gun cable of the charging gun 40.

[0061] In this way, the degree of automation of the operation of the gun rack 30 and the charging gun 40 is improved.

[0062] Please refer to Figure 2 In some embodiments, when the cover plate 20 covers the opening 11, a gap 12 can be formed between the cover plate 20 and the opening 11, through which the gun wire can pass out, and when the charging gun 40 is in use, the gun rack 30 can be moved into the accommodating cavity after the charging gun 40 is taken out, the cover plate 20 covers the opening 11, and the gun wire passes out through the gap 12.

[0063] It can be understood that the size of the cover plate 20 is smaller than the size of the opening 11, and the cover plate 20 cannot completely cover the opening 11.

[0064] After the gun rack 30 and the charging gun 40 are moved out of the accommodating cavity for the first time, the charging gun 40 is in use. When the user takes the charging gun 40 off the gun rack 30, the first driving member 50 starts to operate, the gun rack 30 can be moved into the accommodating cavity, and the cover plate 20 can cover the opening 11. The take-up and pay-off assembly 80 does not operate synchronously with the first driving member 50, and the charging gun 40 is always located outside the accommodating cavity, and the gun wire of the charging gun 40 can extend out of the accommodating cavity through the gap 12 to ensure the normal operation of the charging gun 40.

[0065] When the charging gun 40 is used, the user can control the gun rack 30 to place the used charging gun 40 again through the APP that can control the operation of the charging pile 100, and then carry the charging gun 40 into the accommodating cavity through the gun rack 30. At this stage, the take-up and pay-off assembly 80 starts to wind the gun wire.

[0066] In summary, when the charging gun 40 is used, the gun rack 30 can be retracted into the accommodating cavity, thereby reducing the probability of damage caused by interference between the gun rack 30 and external components.

[0067] In some embodiments, the state between the charging gun 40 and the gun rack 30 is always detected by the detector. When the charging gun 40 is in use, when the detector detects that the charging gun 40 is separated from the gun rack 30, the first driving member 50 drives the first transmission member 60 to operate, and the gun rack 30 is moved into the accommodating cavity.

[0068] The detector can send a signal to the first driving member 50 when the charging gun 40 is separated from the gun rack 30 for the first time, the first driving member 50 can drive the first transmission member 60 to operate and drive the gun rack 30 to move into the accommodating cavity. When the charging gun 40 is used and installed on the gun rack 30, the detector can send a signal to the first driving member 50 again, the first driving member 50 can drive the first transmission member 60 to operate and drive the gun rack 30 to move into the accommodating cavity.

[0069] In this way, the electrical connection between the charging gun 40 and the gun rack 30 is simplified, and the automation of the gun rack 30 and the charging gun 40 is improved.

[0070] Please continue to refer to Figure 2 In some embodiments, the opening 11 is formed in the bottom of the housing 10, and the charging pile 100 further comprises a support (not shown in the figure), and the housing 10 is installed on the top of the support, so that the opening 11 faces the bottom of the support.

[0071] Because the opening 11 faces the bottom of the support, the gun rack 30 can move into or out of the accommodating cavity along the direction of gravity, which reduces the difficulty of driving the gun rack 30 to move by the first driving member 50. In addition, arranging the housing 10 on the top of the support also reduces the space occupied by the housing 10 on the ground, thereby reducing the space occupied by the charging pile 100 on the ground.

[0072] It should be noted that the first driving member 50 and the winding and unwinding assembly 80 are each provided with at least two position sensors. The position sensors on the first driving member 50 are arranged at different positions, and different position sensors are used to detect the running degree of the driving shaft of the first driving member 50 to reflect the lowering degree of the first driving member 60, so as to transmit relevant information to the first driving member 50, thereby reminding whether the first driving member 50 continues to run, so that the user does not need to manually turn off the first driving member 50, and the degree of automation of the first driving member 50 is improved.

[0073] The functions of the position sensors on the winding and unwinding assembly 80 are the same as those of the position sensors on the first driving member 50, and will not be described here.

[0074] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0075] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
