DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0017] like Figures 1 to 6As shown, an automatically retractable new energy charging pile of the present invention comprises a base 1, a charging pile 2 and two limiting plates 3 arranged on the base 1, wherein the base 1 is buried underground, the charging pile 2 and the limiting plates 3 are exposed on the ground, and the charging pile 2 is used to limit the parking position of the vehicle to be charged; The base 1 is hollow inside, and two partitions 4 are arranged inside the base 1. The two partitions 4 divide the internal space of the base 1 into a storage chamber located in the middle and side chambers located on both sides. The two side chambers correspond to two limiting plates 3 respectively. The storage chamber is used to store the charging pile 2 in a tilted state. A movable plate 5 is arranged in the storage chamber. Two first slide columns 7 are arranged on each side wall on the front and rear sides of the movable plate 5. Two first guide grooves 6 are provided on the partition 4. One first guide groove 6 is horizontal, and the other first guide groove 6 is inclined. The two first slide columns 7 on the side walls of the movable plate 5 are slidably inserted into the two first guide grooves 6 on the partition 4 respectively. Among them, the base 1 is provided with a storage opening and two long openings on both sides of the storage opening on the top, the storage opening is connected with the storage cavity, the long opening is connected with the side cavity, the bottom of the charging pile 2 passes through the storage opening and is fixedly connected with the movable plate 5, a transmission structure is provided in the side cavity, the bottom of the limiting plate 3 passes through the long opening and extends into the side cavity, the transmission structure is used to transmit the first sliding column 7 in the horizontal first guide groove 6 on the limiting plate 3 and the partition plate 4, and an auxiliary column 8 for providing auxiliary support to the charging pile 2 is provided in the storage cavity.

[0018] In detail, the charging pile 2 corresponds to the storage port and the storage cavity, the movable plate 5 is located in the storage cavity, the limiting plate 3 corresponds to the long port and the side cavity, the bottom of the limiting plate 3 extends into the side cavity, and the first guide groove 6 runs through the partition 4, so the first slide column 7 on the movable plate 5 can extend from the storage cavity through the first guide groove 6 to the side cavity, so that the first slide column 7 in the first guide groove 6 in the horizontal state on the partition 4 is connected to the transmission structure, the first guide groove 6 in the horizontal state on the partition 4 is located on the lower side of the partition 4, and the first guide groove 6 in the inclined state is located on the upper side of the partition 4, the bottom of the auxiliary column 8 is rotatably installed in the storage cavity, and the top of the auxiliary column 8 extends upward to the side wall position of the charging pile 2 and is rotatably connected with the charging pile 2.

[0019] Since the limiting plate 3 is connected to the charging pile 2 through the transmission structure, when the limiting plate 3 moves toward the charging pile 2, the transmission structure will reversely pull the first sliding column 7 to slide in the first guide groove 6 toward the limiting plate 3. At this time, the movable plate 5 moves in the opposite direction, and the movable plate 5 drives the charging pile 2 to move in the opposite direction toward the limiting plate 3, so that the charging pile 2 and the limiting plate 3 move in the opposite direction synchronously. Since the charging pile 2 is guided by the two first sliding columns 7 on the side wall of the movable plate 5 and the two first guide grooves 6 on the partition 4, the first sliding column 7 on the lower side of the side wall of the movable plate 5 moves horizontally, and the first sliding column 7 on the upper side moves tiltedly, and the distance between the two first sliding columns 7 is fixed. Therefore, as the movable plate 5 moves, the tilt angle of the movable plate 5 gradually increases, and the movable plate 5 changes from vertical to vertical. The state gradually flips to the inclined state, at this time the moving plate 5 drives the charging pile 2 to move synchronously, so that the charging pile 2 in the vertical state gradually tilts and tilts, and the moving plate 5 carries the charging pile 2 and gradually tilts it into the storage cavity, so that the charging pile 2 can be hidden, and the setting of the auxiliary column 8 mainly plays an auxiliary supporting role for the charging pile 2. When the charging pile 2 tilts, the charging pile 2 pulls the auxiliary column 8 to rotate synchronously and is stored in the storage cavity. Since the movement trajectory of the charging pile 2 is limited by the two first guide grooves 6 on the partition 4 and the two first sliding columns 7 in the two first guide grooves 6, the auxiliary column 8 only plays an auxiliary supporting role. When the auxiliary column 8 interferes with the movement trajectory of the charging pile 2, the auxiliary column 8 can be used with a telescopic rod or other structures with certain telescopic functions.

[0020] In actual use, the vehicle to be charged gradually approaches the two limiting plates 3, which limit the parking position of the vehicle, thereby serving as a warning to the driver. When the vehicle continues to move toward the limiting plates 3 and contacts the limiting plates 3 due to driver error or other reasons, the vehicle will push the limiting plates 3 to move on the base 1, and the limiting plates 3 will pull the charging pile 2 to fall and hide in the storage cavity through the transmission structure, thereby avoiding a direct collision between the vehicle and the charging pile 2, thereby providing an anti-collision function for the charging pile 2. In addition, when the charging pile 2 moves, its bottom moves toward the direction of the vehicle and its top falls away from the vehicle, thereby realizing a rapid dumping and avoidance function of the charging pile 2 in a limited space. In addition, this movement mode can reduce the space occupied by the charging pile 2, and to avoid the charging pile 2 from falling directly backwards, it is also necessary to leave space for the charging pile 2 to move on the rear side of the charging pile 2 to reduce the floor space.

[0021] It should be pointed out that since the moving power of the charging pile 2 is provided by the movement of the limit plate 3, when the limit plate 3 moves to a certain position, the charging pile 2 will move synchronously to the specified position and angle, so that there is no need to set a large interval between the limit plate 3 and the charging pile 2, and the charging pile 2 can be folded up before the vehicle hits the charging pile 2 to reduce the parking space. At the same time, since the storage movement of the charging pile 2 and the movement of the limit plate 3 are connected by a mechanical structure, the synchronization is stronger, and there is no need to control it through other electronic equipment, which reduces the reaction delay time and facilitates the rapid adjustment of the charging pile 2 to be folded up according to the position of the limit plate 3, thereby avoiding the problem of untimely response caused by the long storage time of the charging pile 2.

[0022] When the vehicle approaches the charging pile 2 due to an operational error, the anti-collision mechanism of the charging pile 2 is automatically triggered, and the charging pile 2 is driven to quickly dump and hide in the storage cavity by moving the limiting plate 3, effectively preventing the vehicle from directly hitting the charging pile 2, thereby protecting the charging pile 2 from damage and reducing potential safety risks; through the special dumping avoidance mechanism of the charging pile 2, that is, the bottom moves toward the vehicle and the top dumps away from the vehicle, the charging pile 2 can quickly complete the avoidance action in a limited space, without reserving a large amount of additional space for the charging pile 2 to dump behind, thereby saving precious ground resources, which is particularly suitable for urban environments with compact space; the movement trajectory of the charging pile 2 is controlled by the two first guide grooves 6 and the two The precise guidance of the first sliding column 7 ensures the stability and controllability of the charging pile 2 during the tipping process. At the same time, the auxiliary column 8, as an auxiliary supporting mechanism, not only ensures the smooth transition of the charging pile 2 during the tipping process, but also can synchronously rotate and be stored in the storage cavity when the charging pile 2 is tipped, reducing the mutual interference between moving parts and improving the reliability of the overall system; the limiting plate 3 not only limits the parking position of the vehicle, but also serves as a warning when the driver makes an operational error, thereby enhancing the user's sense of security during the charging process; in summary, this design of a new energy charging pile that can be automatically folded not only solves the problem that the charging pile 2 is easily damaged by collision, but also optimizes space utilization, improves safety and user experience, and is an innovative and practical technical solution.

[0023] like Figure 5 As shown, a guide rail 9 is provided in the side chamber, and the limiting plate 3 is slidably mounted on the guide rail 9; The transmission structure includes two transmission wheels 10 rotatably mounted in the side chamber, the connection direction of the two transmission wheels 10 is along the length direction of the side chamber, and a transmission chain 11 is provided on the two transmission wheels 10, one side of the transmission chain 11 is connected to the limiting plate 3, and the other side of the transmission chain 11 is connected to the first sliding column 7 in the first guide groove 6 in the horizontal state on the partition 4, and a reset motor 12 is provided on one transmission wheel 10, and the reset motor 12 is fixed in the side chamber; Wherein, a locking structure is provided between the auxiliary column 8 and the charging pile 2 .

[0024] In detail, the position of the charging pile 2 can be conveniently locked through the locking structure to prevent it from moving randomly. In the natural state, the reset motor 12 is in a power-off state. When the vehicle contacts the limiting plate 3 and pushes the limiting plate 3 to move, the limiting plate 3 will drive the transmission chain 11 and the two transmission wheels 10 to move. Since the movement directions of the two sides of the transmission chain 11 are opposite, the guide rail 9 will drive the first sliding column 7 to move in the opposite direction through the transmission chain 11, that is, the limiting plate 3 and the moving plate 5 move in the opposite direction, thereby providing power for the movement of the charging pile 2.

[0025] It should be pointed out that when the vehicle pushes the limiting plate 3 to move, the charging pile 2 overcomes the limitation of the locking structure and tilts over. When the vehicle leaves the charging position, the reset motor 12 can be energized and controlled to run through the central control box or other automatic control units. The reset motor 12 will drive the limiting plate 3 and the charging pile 2 to reset, and use the locking structure to re-limit the position of the charging pile 2.

[0026] like Figure 2 As shown, the locking structure includes a baffle 13 rotatably mounted on the charging pile 2 , the baffle 13 and the charging pile 2 are connected via a leaf spring 14 , the leaf spring 14 provides elastic thrust to the baffle 13 and makes the baffle 13 close to the auxiliary column 8 .

[0027] In detail, the leaf spring 14 provides an elastic thrust to the baffle 13 and makes the baffle 13 stick to the auxiliary column 8, so that the baffle 13 has a limiting effect on the auxiliary column 8, and reversely has a limiting effect on the charging pile 2, avoiding the auxiliary column 8 and the charging pile 2 from moving relative to each other at will. The position of the charging pile 2 is limited, and when the limiting plate 3 moves, the moving plate 5 exerts a force on the charging pile 2 and overcomes the limitation of the leaf spring 14, so that the baffle 13 is separated from the auxiliary column 8, so that the auxiliary column 8 and the charging pile 2 can be smoothly dumped.

[0028] like Figure 2 As shown, the limiting plate 3 is composed of a first sub-plate 15 located on the outside of the base 1 and a second sub-plate 16 located in the side chamber. The second sub-plate 16 is slidably installed on the guide rail 9. The first sub-plate 15 is docked with the second sub-plate 16 and is rotatably connected. A guide unit for limiting the position of the first sub-plate 15 on the second sub-plate 16 is provided in the side chamber.

[0029] In detail, the guide unit on the first sub-plate 15 can limit the position of the first sub-plate 15 on the second sub-plate 16, that is, when the vehicle pushes the limiting plate 3 to move, the first sub-plate 15 and the second sub-plate 16 remain in a vertical state, and the first sub-plate 15 and the second sub-plate 16 move synchronously. When the charging pile 2 is tilted, the vehicle continues to push the limiting plate 3 to move, and the guide unit guides the first sub-plate 15 to tilt and rotate on the second sub-plate 16, so that the first sub-plate 15 avoids the vehicle, thereby preventing the limiting plate 3 from bending and being damaged when the vehicle continues to push the limiting plate 3.

[0030] like Figure 2 and Figure 5 As shown, the guide unit includes a connecting rod 17 rotatably mounted on the side wall of the first split plate 15, the bottom of the connecting rod 17 extends into the side chamber, and two second sliding posts 18 are parallelly arranged on the side wall of the connecting rod 17 in the side chamber, and a second guide groove 19 is opened on the inner side wall of the side chamber, and the second guide groove 19 consists of a horizontal part and an inclined part. The two second sliding posts 18 are both slidably mounted in the second guide groove 19. When the two second sliding posts 18 slide in the horizontal part of the second guide groove 19, the first split plate 15 is vertical, and when the two second sliding posts 18 slide in the inclined part of the second guide groove 19, the first split plate 15 tilts and rotates on the second split plate 16.

[0031] In detail, the connecting rod 17 passes through the long opening, and the top of the connecting rod 17 is rotatably connected to the side wall of the first split plate 15. The axes of the two second sliding posts 18 are parallel to each other, and the axis of the second sliding post 18 is perpendicular to the moving direction of the limiting plate 3. When the vehicle pushes the limiting plate 3 to move, the first split plate 15 on the limiting plate 3 will drive the two second sliding posts 18 to slide in the horizontal part of the second guide groove 19 through the connecting rod 17. At this time, due to the guiding effect of the two second sliding posts 18 on the connecting rod 17 and the height limitation of the two second sliding posts 18, the first split plate 15 cannot rotate on the second split plate 16. Therefore, the first split plate 15 and the second split plate 16 remain in a vertical state and move synchronously. When the two second sliding posts 18 move to the inclined part of the second guide groove 19, the two second sliding posts 18 drive the connecting rod 17 to tilt, and the connecting rod 17 pulls the first split plate 15 to tilt, thereby causing the first split plate 15 to tip over on the second split plate 16.

[0032] It should be pointed out that since the limiting plate 3 needs to drive the charging pile 2 to move when it moves initially, the strength requirement for the limiting plate 3 is relatively high, that is, the first sub-plate 15 and the second sub-plate 16 cannot be softly connected by other structures such as springs, and the connecting rod 17, the second sliding column 18 and the second guide groove 19 are required to realize the hard connection between the first sub-plate 15 and the second sub-plate 16.

[0033] like Figure 3 and Figure 6As shown, a plurality of first baffles 20 are arranged between the two baffles 4, the plurality of first baffles 20 are arranged side by side, and two adjacent first baffles 20 are rotatably connected, and a third slide post 21 is arranged at both ends of the first baffle 20 facing the two baffles 4, and a third guide groove 22 is opened on the side wall of the baffle 4, and the third slide post 21 is slidably installed on the third guide groove 22; Among them, a plurality of first shielding plates 20 shield the storage opening, and a first first shielding plate 20 among the plurality of first shielding plates 20 is rotatably connected to the charging pile 2 .

[0034] In detail, multiple first baffles 20 form a deformable cover to block the storage opening, which can prevent leaves, weeds and other debris from falling into the storage cavity. The third slide column 21 and the third guide groove 22 can be used to guide the first baffle 20. When the charging pile 2 is tilted, the charging pile 2 can push the multiple first baffles 20 to move synchronously, and the third slide column 21 slides in the third guide groove 22.

[0035] It should be pointed out that, since displacement between the charging pile 2 and the first first shield 20 is likely to occur when the charging pile 2 is tipped over, an auxiliary plate may be added to achieve connection between the charging pile 2 and the first first shield 20 .

[0036] like Figure 7 As shown, a second baffle 23 and a third baffle 24 are slidably provided in the side chamber, and the sliding direction of the second baffle 23 and the third baffle 24 is consistent with the moving direction of the limiting plate 3, the second baffle 23 and the third baffle 24 are used to block the long opening, the second baffle 23 and the third baffle 24 are located on the left and right sides of the second sub-plate 16, the second baffle 23 is fixed on the second sub-plate 16, the third baffle 24 abuts against the second sub-plate 16, and the third baffle 24 and the second sub-plate 16 are connected by a buffer cotton 27, and a notch 26 is opened on the third baffle 24, and the connecting rod 17 passes through the notch 26.

[0037] In detail, the second baffle 23 and the third baffle 24 can be used to conveniently block the long opening, thereby conveniently closing and isolating the side chamber. When the limiting plate 3 moves, it can drive the second baffle 23 and the third baffle 24 to move synchronously. When the first sub-plate 15 is tilted on the second sub-plate 16, the connecting rod 17 moves away from the second sub-plate 16, and the connecting rod 17 pushes the third baffle 24 away from the second sub-plate 16. The spring piece 25 undergoes elastic deformation, and the connecting rod 17 passes through the notch 26 to produce relative sliding.

[0038] like Figure 1 to Figure 2 As shown, a buffer cotton 27 and a laser rangefinder 28 are provided on the side wall of the limiting plate 3 away from the charging pile 2 , and an alarm 29 is provided on the side wall of the limiting plate 3 facing the charging pile 2 .

[0039] In detail, the buffer cotton 27 is used to provide buffer protection for the vehicle when the vehicle contacts the limiting plate 3, and the laser rangefinder 28 is used to measure the distance between the vehicle and the limiting plate 3. When the distance exceeds a critical value when the vehicle approaches the limiting plate 3, the alarm 29 sounds an alarm and reminds the driver to prevent the limiting plate 3 from contacting the vehicle, which can further achieve an anti-collision effect. The laser rangefinder 28 and the alarm 29 can be controlled by electronic equipment such as a central control box and a controller.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
