Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and particularly to a charging pile base. Background Art

[0002] The function of a charging pile is similar to that of a fuel dispenser in a gas station. It can be fixed on the ground or wall, installed in public buildings, residential community parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] Existing charging piles are usually directly and firmly installed on the ground or wall. When maintenance and replacement of the charging pile are required, it takes cumbersome operations to disassemble and replace the charging pile, which is time-consuming and laborious, with a large labor intensity for installation and disassembly and low efficiency. Summary of the Invention

[0004] The technical problem to be solved and the technical task proposed by the present invention are to improve the prior art, provide a charging pile base, and solve the problems of inconvenient installation, disassembly, maintenance, large labor intensity and low efficiency of the charging pile in the current technology.

[0005] To solve the above technical problems, the technical solution of the present invention is:

[0006] A charging pile base includes a housing, a stud and a mounting block. The stud is arranged in the housing. The mounting block is connected to the charging pile body and is inserted into the housing through an installation opening formed on the housing. The mounting block is in threaded connection with the stud. A locking portion is provided on the mounting block. A locking mechanism that moves between an unlocking position and a locking position is arranged in the housing. When the locking mechanism is in the locking position, it engages with the locking portion on the mounting block to lock the movement of the mounting block. The charging pile base of the present invention can conveniently and quickly realize the installation and disassembly of the charging pile. Rotating the charging pile body or the stud can quickly realize the connection and separation of the charging pile body and the stud. The repeated connection has good stability. The threaded connection between the mounting block and the stud is the installation method of the charging pile body. After the mounting block and the stud are connected in place, the locking mechanism switches to the locking position to cooperate with the locking portion on the mounting block to prevent the movement of the mounting block, lock the mounting block and thus realize the installation and locking of the charging pile, avoid the charging pile body being randomly disassembled from the base, improve the installation stability, and also play an anti-theft role. When disassembly is required, first switch the locking mechanism to the unlocking position, and then rotate the charging pile body and the stud relative to each other to separate the charging pile body from the base. The operation is quick and convenient, effectively reducing the labor intensity and having high maintenance efficiency.

[0007] Further, a motor assembly for driving the rotation of the stud is provided inside the housing. The automatic connection and separation of the charging pile can be realized by using the motor assembly. During installation, only the installation block needs to be aligned with the stud. The motor assembly drives the stud to rotate, so that the installation block moves axially along the stud to the proper position, and then the locking mechanism switches to the locking position to complete the entire connection process. During disassembly, first switch the locking mechanism to the unlocking position, and then the motor assembly drives the stud to rotate in the reverse direction, so that the installation block withdraws along the stud in the reverse direction. Finally, when the installation block is separated from the stud, the charging pile body can be disassembled from the base, further improving the disassembly efficiency and reducing the labor intensity of installation and disassembly.

[0008] Further, the locking portion is a groove opened on the installation block. The groove is in a direction perpendicular to the axial direction of the stud. The structure is simple and easy to implement, and the locking stability is good. It can effectively prevent the installation block from rotating relative to the stud and ensure the installation stability of the charging pile body.

[0009] Further, the locking mechanism includes a locking pin assembly and a locking drive assembly. The locking drive assembly drives the locking pin assembly to move in a direction perpendicular to the axial direction of the stud to insert into or withdraw from the locking portion.

[0010] Further, the locking mechanism further includes an adjustment box fixed inside the housing. The locking pin assembly includes a movable plate located inside the adjustment box, a clamping plate located outside the adjustment box, and a connecting rod passing through the wall surface of the adjustment box to connect the movable plate and the clamping plate. The locking drive assembly includes a lead screw rotatably provided on the adjustment box and a threaded sleeve threadedly connected to the lead screw. The threaded sleeve is connected and transmitted with the movable plate. The structure is simple, easy to implement, low in cost, and good in locking stability.

[0011] Further, the lead screw includes two threaded sections with opposite threads. A threaded sleeve is provided on each of the two threaded sections. The axial direction of the lead screw is perpendicular to the moving direction of the locking pin assembly. The two threaded sleeves are respectively connected to the movable plate through a transmission rod. The two ends of the transmission rod are respectively hinged to the threaded sleeve and the movable plate. The structural stability is good, the transmission stability is improved, and the locking stability of the locking mechanism for the installation block is also improved.

[0012] Further, the locking drive assembly further includes a rotating rod passing through the housing for driving the lead screw to rotate. The rotating rod and the lead screw are driven by a gear mechanism. A handwheel is provided on the rotating rod, which is easy to operate.

[0013] Further, it further includes a bottom plate, on which a lifting mechanism for lifting the housing is provided, and a water level detector for controlling the operation of the lifting mechanism is also provided on the base. The water level detector is used to monitor the water level condition of the external environment. When the external environment accumulates water due to excessive rain and reaches the warning level of the water level detector, the lifting mechanism will lift the housing and the charging pile body carried by the housing upward as a whole, thereby effectively preventing the charging pile body from being damaged due to water ingress, and also preventing the components inside the housing from being damaged due to water ingress. It also avoids the rusting of the studs, mounting blocks and locking mechanisms inside the housing, which may cause difficulties in installation and disassembly, and ensures the long-term stable and fast installation and disassembly of the charging pile body. A moisture absorption box is also provided inside the housing to effectively prevent moisture and further avoid the situation where the components inside the housing are damaged or rusted, resulting in jamming, and prolong the service life.

[0014] Further, a fixing plate is also provided on the bottom plate on the side of the housing. A fixing groove is provided on the fixing plate. An elastic pin assembly is provided on the housing, which abuts against the fixing plate and is in an elastic energy storage state. When the housing is lifted by the lifting mechanism until the elastic pin assembly is at the same height as the fixing groove, the elastic pin assembly releases the stored energy and inserts into the fixing groove. The fixing groove plays a role in limiting the lifting height of the housing. After the elastic pin assembly inserts into the fixing groove, the fixing plate plays a role in supporting the housing, which can improve the stability of the housing and the charging pile body carried by the housing after being lifted.

[0015] Further, a pushing mechanism for pushing the elastic pin assembly out of the fixing groove is provided in the fixing groove. The elastic pin assembly includes a pin box fixed on the housing, a pin rod penetrating out of the pin box, and a spring in the pin box for pushing the pin rod. The structure is simple and easy to implement.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] A charging pile base disclosed in an embodiment of the present invention is convenient and simple to install and disassemble, effectively reducing the labor intensity. The connection stability between the charging pile and the base is good, ensuring the use stability and reliability of the charging pile.

[0024] As Figures 1 to 3 shown, a charging pile base mainly includes a housing 1, a stud 2, and a mounting block 3. The stud 2 is arranged inside the housing 1. An electric motor assembly 4 for driving the rotation of the stud 2 is arranged inside the housing 1. The mounting block 3 is connected to the charging pile body a and is inserted into the housing 1 through an installation opening provided on the housing 1. The mounting block 3 is threadedly connected to the stud 2. A locking portion 31 is arranged on the mounting block 3. A locking mechanism 5 that moves between an unlocking position and a locking position is arranged inside the housing 1. When the locking mechanism 5 is in the locking position, it engages with the locking portion 31 on the mounting block 3 to lock the movement of the mounting block 3. A rain cover is sleeved on the surface of the charging pile body, and the bottom of the rain cover contacts the housing.

[0025] Specifically, the electric motor assembly 4 is fixed at the bottom of the housing 1. The stud 2 is directly connected to the output end of the electric motor assembly 4. The stud 2 is along the vertical direction. An installation opening is provided at the top of the housing 1. The mounting block 3 is fixedly connected to the bottom of the charging pile body a. When the mounting block 3 is inserted into the housing 1 through the installation opening, a part of the bottom of the charging pile body a also enters the housing 1 through the installation opening.

[0026] In this embodiment, the locking portion 31 is a groove provided on the mounting block 3. The groove is located in a direction perpendicular to the axial direction of the stud 2, that is, the locking portion 31 is provided on both lateral sides of the mounting block 3 in the transverse direction, and a locking mechanism 5 is provided on both lateral sides of the mounting block 3 respectively.

[0027] The locking mechanism 5 mainly includes a locking pin assembly 51 and a locking driving assembly 52. The locking driving assembly 52 drives the locking pin assembly 51 to move in a direction perpendicular to the axial direction of the stud 2 to insert into or withdraw from the locking portion 31. When the locking pin assembly 51 inserts into the locking portion 31, it means that the locking mechanism 5 switches to the locking position. When the locking pin assembly 51 withdraws from the locking portion 31, it means that the locking mechanism 5 switches to the unlocking position.

[0028] Specifically, the locking mechanism 5 further includes an adjustment box 53 fixed inside the housing 1. The locking pin assembly 51 includes a movable plate 511 located inside the adjustment box 53, a clamping plate 512 located outside the adjustment box, and a connecting rod 513 passing through the wall surface of the adjustment box 53 to connect the movable plate 511 and the clamping plate 512. The locking drive assembly 52 includes a lead screw 521 rotatably arranged on the adjustment box 53 and a threaded sleeve 522 threadedly connected to the lead screw 521. The threaded sleeve 522 is connected and drives the movable plate 511. The rotation of the lead screw 521 will drive the threaded sleeve 522 to move along the axial direction of the lead screw 521. Then, the threaded sleeve 522 drives the movable plate 511 to move through a transmission member, finally realizing the movement of the locking pin assembly 51 between the locking position and the unlocking position. The movable plate 511, the clamping plate 512, and the connecting rod 513 move as a whole along a direction perpendicular to the axial direction of the stud 2. Two connecting rods 513 are arranged in parallel and spaced between the movable plate 511 and the clamping plate 512. The cross-sectional size of the movable plate 511 is equivalent to that of the adjustment box 53, so as to ensure that the locking pin assembly 51 can move stably and accurately along the transverse direction;

[0029] Further, the lead screw 521 includes two threaded sections with opposite threads. A threaded sleeve 522 is arranged on each of the two threaded sections. The axial direction of the lead screw 521 is perpendicular to the movement direction of the locking pin assembly 51. The two threaded sleeves 522 are respectively connected to the movable plate 511 through a transmission rod 523. Both ends of the transmission rod 523 are hinged to the threaded sleeve 522 and the movable plate 511 respectively. When the lead screw 521 rotates, the two threaded sleeves 522 move in opposite directions along the axial direction of the lead screw 521. The threaded sleeve 522 drives the movable plate 511 to move through the hinged transmission rod 523. The included angle between the two transmission rods 523 changes, so that the movable plate 511 moves in the axial direction perpendicular to the lead screw 521. In this embodiment, that is, the movable plate 511 moves along the transverse direction, so that the clamping plate 512 is inserted into the groove-shaped locking portion 31 to reach the locking position or the clamping plate 512 withdraws from the groove-shaped locking portion 31 to reach the unlocking position.

[0030] In this embodiment, the locking drive assembly 52 further includes a rotating rod 524 passing through the housing 1 for driving the rotation of the lead screw 521. A gear mechanism is provided between the rotating rod 524 and the lead screw 521. A handwheel 525 is arranged on the rotating rod 524 to facilitate the rotation of the rotating rod 524. Specifically, the lead screw 521 passes through the adjustment box 53. A first bevel gear is arranged on the lead screw. A second bevel gear is arranged on the rotating rod 524. The first bevel gear meshes with the second bevel gear, so that when the rotating rod 524 rotates, the lead screw 521 can be driven to rotate, and further drive the locking pin assembly 51 to move between the locking position and the unlocking position along the transverse direction.

[0031] When installing the charging pile body a, insert the bottom of the charging pile body a into the installation opening of the housing 1 so that the installation block 3 is aligned with the stud 2. Then, the motor assembly 4 starts to work to drive the stud to rotate, thereby automatically screwing the installation block and the stud together. And the installation block 3 moves axially along the stud 2 to the proper position. Then, operate the rotating rod 524 to make the lead screw 521 rotate, so that the clamping plate 512 of the locking pin assembly 51 enters the locking portion 31 of the installation block 3, completing the entire installation operation. The charging pile body a is quickly and reliably connected by screwing the installation block 3 and the stud 2, and the locking pin assembly 51 is used in cooperation with the groove-shaped locking portion 31 to lock the installation block 3. At this time, the installation block 3 cannot rotate or directly move axially along the screw rod, thus ensuring the stable installation of the charging pile body a;

[0032] When it is necessary to disassemble the charging pile body a, first operate the rotating rod 524 in the reverse direction to make the lead screw 521 rotate, so that the clamping plate 512 of the locking pin assembly 51 exits from the locking portion 31 of the installation block 3. Then, the motor assembly 4 starts to work in the reverse direction to drive the stud 2 to rotate in the reverse direction. The installation block 3 moves axially in the reverse direction along the stud 2 and finally separates from the stud 2. Finally, the charging pile body a is separated and disassembled from the base. The operation is quick and convenient, effectively reducing the labor intensity and having high maintenance efficiency.

[0033] The locking mechanism can also adopt a locking pin structure driven by a cylinder, a hydraulic cylinder, or an electric push rod. Similarly, it performs a telescopic action between the locked position and the unlocked position. After the installation block 3 and the stud 2 are connected in place, the cylinder, the hydraulic cylinder, or the electric push rod drives the locking pin to insert into the groove-shaped locking portion 31 to lock the installation block 3, realizing the stable installation of the charging pile body a. When it is necessary to disassemble the charging pile body a, the cylinder, the hydraulic cylinder, or the electric push rod drives the locking pin to withdraw from the groove-shaped locking portion 31, and then the installation block 3 separates from the stud 2. The disassembly is convenient and efficient.

[0034] The charging pile base further includes a bottom plate 6. A lifting mechanism 7 for lifting the housing 1 is provided on the bottom plate 6. A water level detector 8 for controlling the operation of the lifting mechanism 7 is also provided on the base. The water level detector 8 detects the water level condition of the external environment. When the water level of the external environment reaches the warning level, the water level detector 8 controls the lifting mechanism 7 to start working. The lifting mechanism 7 lifts the housing and the charging pile body carried by the housing as a whole, effectively preventing water from entering the housing and the charging pile body, ensuring the integrity of the charging pile, extending the service life. And, a moisture absorption box 9 is provided inside the housing 1. One moisture absorption box 9 is provided on each side of the motor assembly 4, further reducing the influence of environmental humidity on the components inside the housing, preventing the studs, installation blocks, and locking mechanisms inside the housing from rusting, which may cause difficulties in installation and disassembly, and ensuring the long-term stable and quick installation and disassembly of the charging pile body.

[0035] The bottom plate 6 is further provided with fixing plates 61 located on both sides of the housing 1. On the side of the fixing plate 61 facing the housing, there is a fixing groove 62. On both sides of the housing 1, there is respectively an elastic pin assembly 63 that abuts against the fixing plate 61 and is in an elastic energy storage state. The elastic pin assembly 63 elastically expands and contracts in the transverse direction. When the housing 1 is not lifted by the lifting mechanism 7, the height where the fixing groove 62 is located is higher than the height where the elastic pin assembly 63 is located. When the housing 1 is lifted by the lifting mechanism 7 to the same height as the elastic pin assembly 63 and the fixing groove 62, the elastic pin assembly 63 releases the stored energy to insert into the fixing groove 62.

[0036] The fixing groove 62 is provided with a pushing mechanism 64 for pushing the elastic pin assembly 63 out of the fixing groove 62. The pushing mechanism 64 is composed of a top plate located in the fixing groove 62 and a push rod connected to the top plate. The push rod penetrates out from the side of the fixing plate 61 away from the housing 1. By operating the push rod, the elastic pin assembly 63 can be pushed out of the fixing groove 62. The elastic pin assembly 63 includes a pin box 631 fixed on the housing 1, a pin rod 632 penetrating out of the pin box 631, and a spring 633 in the pin box 631 for pushing the push rod 632. When the housing 1 is not lifted by the lifting mechanism 7, the pin rod 632 abuts against the surface of the fixing plate 61 under the action of the spring 633. Then, when the housing 1 is lifted by the lifting mechanism 7 to the same height as the elastic pin assembly 63 and the fixing groove 62, the spring 633 releases the elastic force to further push the pin rod 632 out of the pin box 631 and into the fixing groove 62. After the pin rod 632 is inserted into the fixing groove 62, the fixing plate 61 plays a supporting role for the housing, which can improve the stability of the housing and the charging pile body carried by the housing after being lifted.

[0037] Specifically, the lifting mechanism 7 uses a cylinder. The lifting mechanism 7 is supported on the pin box 631, that is, the lifting mechanism 7 is respectively provided with one on both sides of the housing 1, and the lifting mechanisms 7 on both sides act synchronously to lift the housing and the charging pile body carried by the housing as a whole upward.

[0038] The above is only the preferred embodiment of the present invention. It should be noted that the above preferred embodiment should not be regarded as a limitation of the present invention. The protection scope of the present invention should be subject to the scope defined by the claims. For those of ordinary skill in the art of this technology, without departing from the spirit and scope of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
