[0031] The present invention provides a charging pile. Figures 1 to 3 This is an embodiment of the charging pile provided by the present invention.

[0032] Please also refer to Figures 1 to 2 , the charging pile body 1, the manipulator 2 and the protective structure 4, wherein the body 1 forms a protective cavity with an opening, a charging gun 3 is provided in the protective cavity, the fixed end of the manipulator 2 is mounted on the cavity wall of the protective cavity, and the free end of the manipulator 2 is mounted with the charging gun 3, the protective structure 4 includes two protective doors 41 and two shielding components 42, the two protective doors 41 are slidably connected to the opening of the protective cavity, and the two protective doors 41 can move in the direction of approaching or moving away from each other to close or open the opening of the protective cavity, each of the shielding components 42 includes a plurality of baffles 421, and the plurality of baffles 421 are respectively slidably connected to the corresponding protective doors 41, and the plurality of baffles 421 can slide toward the direction of the other protective door 41. When the two protective doors 41 close the opening of the protective cavity, the plurality of baffles 421 slide between the two protective doors 41 to close the interval space between the two protective doors 41.

[0033] When the charging gun 3 needs to be used, the two protective doors 41 are first driven to move so that the two protective doors 41 move away from each other, thereby opening the protective cavity and revealing the manipulator 2 and the charging gun 3. Then, the manipulator 2 is started to drive the charging gun 3 to separate from the charging port on the main body 11, and move the charging gun 3 to the outside of the protective cavity. Then, the charging gun 3 is inserted into the charging port of the car. After the charging gun 3 is matched with the charging port of the car, the car is started to be charged. At the same time, the two protective doors 41 are driven to move towards each other, and the two protective doors 41 drive the baffle 421 to move together. Because the part of the manipulator 2 that passes through the protective cavity is still located in the protective cavity, the two protective doors 41 cannot be fitted together to close the protective cavity, resulting in a certain space between the two protective doors 41. Therefore, a plurality of slidingly connected baffles 421 are provided on the opposite sides of the two protective doors 41. When the two protective doors 41 are moved into place, some of the baffles 421 on the two protective doors 41 fit together to close. The protective cavity, the remaining baffle 421 is blocked by the manipulator 2, and one end is in contact with the manipulator 2, and the entire baffle 421 stops moving. One end of the remaining baffle 421 is in contact with the manipulator 2, thereby closing the cavity around the manipulator 2, thereby cooperating with the protective door 41 to close the entire protective cavity, making it difficult for foreign objects to enter the charging gun 3 adapter slot in the main body 1 during charging and affect the resetting of the charging gun 3. At the same time, the manipulator 2 is used to carry the charging gun 3 for charging, so as to avoid the user from being pinched by the protective door 41 in advance due to program errors or erroneous operations when taking and placing the charging gun 3, and the baffle 421 is also slidably connected to the protective door 41, so that an interval space is formed between the two protective doors 41, which is closed by the baffle 421, and the baffle 421 will not continue to move if it touches an object, thereby avoiding the manipulator 2 from being clamped and damaged by the protective door 41, and also avoiding the risk of some users being pinched by putting their hands into the protective cavity for operation.

[0034] The movement of the two protective doors 41 requires the help of external force, and the two protective doors 41 need to move towards or away from each other at the same time. Therefore, a corresponding mechanical structure is required to drive the two protective doors 41 to move together. A more common structure is a threaded rod structure. Two sets of threads are symmetrically arranged on the threaded rod. The two sets of threads are respectively adapted to a threaded sleeve. Each threaded sleeve is connected to the protective door 41. By rotating the threaded rod, the two threaded sleeves move along the axial direction of the threaded rod toward or away from each other, thereby driving the two protective doors 41 to move toward or away from each other. This solution does not limit the specific composition of this structure.

[0035] Therefore, in the technical solution provided by the present invention, the fixed end of the manipulator 2 is installed on the cavity wall of the protective cavity, the free end of the manipulator 2 is installed with the charging gun 3, the protective structure 4 includes two protective doors 41 and two shielding components 42, the two protective doors 41 are slidably connected to the opening of the protective cavity, and the two protective doors 41 can move in the direction of approaching or moving away from each other to close or open the opening of the protective cavity, each of the shielding components 42 includes a plurality of baffles 421, and the plurality of baffles 421 are respectively slidably connected to the corresponding protective cavity. On the protective door 41, multiple baffles 421 can slide toward the direction of the other protective door 41. When the two protective doors 41 close the opening of the protective cavity, multiple baffles 421 slide between the two protective doors 41 to close the interval between the two protective doors 41. The manipulator 2 replaces the user to hold the charging gun 3, so as to avoid the user being pinched by the protective door 41 due to program errors and other reasons during the process of taking and placing the charging gun 3. At the same time, the protective door 41 cooperates with the baffle 421 to prevent foreign matter from entering the protective cavity during charging and affecting other electronic components.

[0036] See also Figure 3 The blocking bar 421 moves with the protective door 41, and the blocking bar 421 is slidably connected to the protective door 41. Under the condition of no restriction, the blocking bar 421 moves with the protective door 41. At the same time, the blocking bar 421 itself will be unable to move to the appropriate position due to the vibration generated during the movement of the protective door 41. Therefore, it is necessary to restrict the blocking bar 421 so that the blocking bar 421 cannot move at will without external force. At the same time, it is also necessary to change the relative position of the blocking bar 421 with respect to the protective door 41 after being subjected to force, and return to the initial position when it is subsequently released from the force state. Specifically, in an embodiment of the present invention, the shielding assembly 42 also includes a plurality of first elastic members 422, one end of each of the first elastic members 422 is connected to the protective door 41, and the other end is connected to the blocking bar 421.

[0037] The function of the first elastic member 422 is to prevent the protective door 41 from sliding freely without external force, and at the same time, after the blocking bar 421 is forced to change its position, it can return to its original position when it is free from force, that is, the first elastic member 422 needs to have elastic potential energy, so the first elastic member 422 can use a spring, one end of the spring is connected to the protective door 41, and the other end is connected to the blocking bar 421. When closing the protective cavity, the two protective doors 41 are driven by the spring to move together in the direction of approaching each other. When the two protective doors 41 are moved into place, there is still a certain distance between the two protective doors 41, which makes the protective door 41 unable to completely close the protective cavity. At this time, the opposite sides of the blocking bars 421 on the two protective doors 41 fit together to close the interval space between the two protective doors 41, thereby completing the sealing work of the entire protective cavity. When the manipulator 2 drives the charging gun 3 to move to the outside of the protective cavity to charge the car, the protective door 41 will close again. At this time, the protective door 41 moves to the position where part of the baffle 421 is used to close the interval between the two protective doors 41. The other baffle 421 is compressed due to the obstruction of the manipulator 2 and will not contact the baffle 421 on the other protective door 41. The end of this part of the baffle 421 away from the spring is attached to the manipulator 2 and arranged around the manipulator 2, thereby closing the distance between the manipulator 2 and the protective door 41 to prevent foreign matter from entering the protective cavity through the gap. When the protective door 41 drives the baffle 421 to move together to close the protective cavity, part of the baffle 421 will collide with the manipulator 2. After a large number of charging times, the baffle 421 may be damaged or the manipulator 2 may be damaged in the collision. Therefore, it is necessary to add components to reduce impact damage.

[0038] Furthermore, a buffer is provided on a side of the blocking bar 421 away from the first elastic member 422 , and when the manipulator 2 drives the charging gun 3 to move to the outside of the protective cavity, the buffer is attached to the manipulator 2 .

[0039] The buffer component prevents the baffle 421 from directly colliding with the manipulator 2, so that the baffle 421 collides with the manipulator 2 with the help of the buffer component. The buffer component is used to weaken the impact damage caused by the baffle 421 colliding with the manipulator 2, thereby extending the service life of the manipulator 2 and the baffle 421. The buffer component can use rubber components such as rubber pads, and the properties of rubber can greatly reduce the damage caused by the collision between the baffle 421 and the manipulator 2.

[0040] The blocking bar 421 is connected to the first elastic member 422 so that the blocking bar 421 can automatically return to its initial position. However, during the recovery process, the blocking bar 421 will slide toward between the two protective doors 41. Once the interaction distance is too far, it will completely detach from the protective door 41. After detaching from the protective door 41, when it moves toward the initial position, it may collide with one side of the protective door 41, causing the blocking bar 421 to be unable to move to the initial position and be blocked between the two protective doors 41. Therefore, it is necessary to limit the sliding distance of the blocking bar 421. Specifically, in the technical solution of the present invention, the protective structure 4 also includes a plurality of limiting components 43, which are arranged between the protective door 41 and the blocking bar 421 to limit the blocking bar 421 from detaching from the protective door 41.

[0041] Furthermore, the limiting assembly 43 includes a limiting member 431 and a limiting groove 432. The limiting member 431 is slidably mounted within the limiting groove 432. One of the limiting member 431 and the limiting groove 432 is provided on the blocking bar 421, and the other is provided on the protective door 41. When the limiting member 431 is provided on the blocking bar 421, a limiting groove 432 that cooperates with the limiting member 431 needs to be provided at a corresponding position on the protective door 41. The limiting groove 432 limits the sliding distance of the limiting member 431, thereby limiting the sliding distance of the blocking bar 421. When the blocking bar 421 slides under the action of the elastic potential energy of the spring, it drives the limiting member 431 to slide within the limiting groove 432. The limiting groove 432 has a limited length, which also limits the sliding length of the blocking bar 421, thereby preventing the blocking bar 421 from completely separating from the protective door 41.

[0042] There are many ways to set up the blocking bar 421, and there are two more common ways. One is to open a groove on the opposite side of the two protective doors 41, and the first elastic member 422 is set in the groove. The blocking bar 421 is slidably connected in the groove and installed at one end of the first elastic member 422. At the same time, part of the blocking bar 421 extends to the outside of the groove. The length of the part extending to the outside of the groove needs to be greater than or equal to half of the distance between the closed protective chambers of the two protective doors 41. The limiting groove 432 is opened in the groove wall of the groove, and a limiting member 431 slidably connected to the limiting groove 432 is set at the corresponding position of the blocking bar 421. At this time, the limiting The shape of the member 431 is not restricted. Another method is to install an elastic member on the side of the two protective doors 41, and install a baffle 421 on the other end of the elastic member. A limiting member 431 is set on the baffle 421, and a limiting groove 432 is opened on the side of the protective door 41 to cooperate with the limiting member 431. At this time, the shape of the limiting member 431 needs to be subject to certain restrictions. The area of ​​the limiting member 431 from the side connected to the baffle 421 to the opposite side needs to be gradually expanded, so that the baffle 421 can only move along the moving direction of the protective door 41, to avoid the baffle 421 from moving arbitrarily, which will only make the protective door 41 unable to complete the closing work after moving into place.

[0043] When the charging pile is not in use, the two protective doors 41 cooperate with the baffle 421 to close the protective cavity, but the baffle 421 is not completely restricted. Under the action of external force, the baffle 421 can compress the first elastic member 422 at any time to open the interval space between the two protective doors 41. Therefore, it is necessary to fix the baffle 421 to prevent the baffle 421 from sliding freely during vibration. Specifically, in the embodiment provided by the present invention, a fixing component 5 is provided on the main body 1, and the fixing component 5 includes a clamping member 51, which is inserted into the baffle 421 to limit the baffle 4 21 is movable, and the clamping member 51 has a limiting position inserted into the baffle 421, and an unlocking position away from the baffle 421. The baffle 421 is clamped by the clamping member 51, so that the baffle 421 will not be easily opened when the charging pile is not in use. Therefore, it is necessary to provide a clamping groove that cooperates with the clamping member 51 on the baffle 421, that is, when in the limiting position, the clamping member 51 clamps the baffle 421 so that the baffle 421 cannot slide even when subjected to external force, and when in the unlocking position, the clamping member 51 is separated from the baffle 421 so that the baffle 421 can slide along the movable direction of the protective door 41 when subjected to external force.

[0044] Furthermore, the fixing assembly 5 includes a movable part 53 and a second elastic part 52. The movable part 53 is slidably connected to the main body 1 and moves toward or away from the baffle 421. One end of the second elastic part 52 is connected to the movable part 53, and the other end is connected to the clamping part 51, so as to push the clamping part 51 from the unlocking position toward the restricting position when the movable part 53 covers the baffle 421.

[0045] When the locking bar 421 is unlocked, the second spring member 52 is pressed against the locking bar 421, and the second spring member 52 is pressed against the locking bar 421, thereby releasing the locking bar 421.

[0046] Sometimes, when a user manually opens the protective door 41 to unlock the blocking bar 421, the user may not move fast enough, causing the protective door 41 to move first and break the clamping member 51, damaging the entire structure. Therefore, it is necessary to set a structure that can limit the contact between the moving protective door 41 and manual operation. Specifically, in an embodiment of the present invention, the clamping member 51 is arranged in an arc shape on the side away from the second elastic member 52.

[0047] The part of the clamping member 51 that is inserted into the clamping slot is set to an arc shape, so that the clamping member 51 can be detached from the clamping slot without the help of an auxiliary structure. It only needs to move the protective door 41 or the movable member 53 to make the clamping slot wall push it out of the clamping slot along the arc surface of the clamping member 51 to release the restriction. At this time, the movable member 53 can be driven by an electric device without the need for manual operation by the user. Space is cleared through the program to reduce the possibility of accidents.

[0048] At the same time, manual operation of the two protective doors 41 is also rather troublesome, and they can also be driven by an electric device. Specifically, in an embodiment of the present invention, two driving components 6 are provided on the main body 1, and the two driving components 6 respectively drive and connect the two protective doors 41, and the two driving components 6 are used to drive the two protective doors 41 toward the opposite side or the back side.

[0049] The simplest structure of the two drive components 6 is two electric push rods or two hydraulic cylinders or other devices that directly push an object to move in a straight line. By simultaneously starting the two electric push rods, the two protective doors 41 are driven to move toward each other or away from each other at the same time. This structural form avoids complex wire connections, reduces the possibility of equipment failure, and reduces costs.

[0050] After the manipulator 2 drives the charging gun 3 to move to the outside of the protective cavity, it needs to continue moving until the charging gun 3 is inserted into the charging socket of the car. The charging socket of the car can be found with the help of an industrial camera. After the charging cavity is inserted into the charging socket, the specific situation of the insertion cannot be identified, and it is impossible to determine whether the plug-in angle is offset. Therefore, it is necessary to contact other structures for judgment. Specifically, in an embodiment of the present invention, a sensor is provided on the outside of the charging gun 3, and the sensor is used to detect the plug-in angle of the charging gun 3.

[0051] The sensor can be a force-controlled sensor, which determines whether the plugging angle of the charging cavity is appropriate through changes in pressure during the plugging process. The pressure value changes detected by the force-controlled sensor are transmitted to the controller. The controller judges the pressure value according to the program and issues instructions to the manipulator 2 based on the judgment result, so that the manipulator 2 adjusts the plugging angle according to the quality to ensure that the charging gun 3 will not cause damage after being inserted into the charging port.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
