Description

Technical Field

[0001] The utility model provides an easily disassembled and pre-buried windproof charging pile, which relates to the field of new energy charging piles. Background Art

[0002] Charging piles, as infrastructure for providing charging services for electric vehicles, function similarly to gas stations for traditional vehicles. They operate by converting AC power from the three-phase grid into DC power through a rectifier circuit. This DC power is then output through a power converter to charge the electric vehicle's battery. With the rapid development of the new energy vehicle industry, the construction and demand for charging piles are also growing.

[0003] For new energy charging piles installed outdoors, refer to their installation environment factors. For example, some charging piles will be exposed to open air environments. Even after installing wind shields, they cannot withstand extreme regions and weather. For example, in windy and rainy weather, due to the appearance characteristics of the charging box, ordinary wind shields cannot fully cover it, causing rain and sand to be blown into the inflation gun and interface under the action of wind force, causing a great impact on the use of the charging pile, greatly increasing the risk of failure, and even threatening the personal safety of people around the charging pile, causing equipment to leak power or even spontaneously combust, posing a huge hidden danger to the safe use of the equipment.

[0004] For example, the patent publication number CN117565717A discloses a street-based pre-buried waterproof charging pile based on V2G technology. Generally, charging piles occupy street space. If the V2G charging pile is installed in a preset pit, the urban space can be reasonably used for vehicle-to-grid interaction. Therefore, this design can adapt to the street environment, does not occupy street space, is used for V2G interaction, and is also waterproof and windproof.

[0005] The problem with this method is that although the charging piles pre-buried in underground space can save street space and be waterproof and windproof, when the charging piles need to be updated, the pre-buried structure is not easy to dismantle, install and repair, which brings trouble to the subsequent equipment maintenance. Utility Model Content

[0006] The utility model provides an easily disassembled and assembled pre-buried windproof charging pile, so as to solve the problem in the prior art that the pre-buried structure is difficult to disassemble, install and repair.

[0007] In order to alleviate the above technical problems, the technical solution provided by the present invention is:

[0008] This easy-to-detach and pre-buried windproof charging pile includes a mobile module;

[0009] The mobile module includes a disassembly shell and a lifting platform;

[0010] A convex block is provided on the top of the lifting platform, and a groove is provided on the convex block;

[0011] A locking mechanism and a driving mechanism are provided inside the disassembly shell;

[0012] The locking mechanism includes a ball and a pressing kit that are clamped in the groove;

[0013] The locking mechanism has a locked state and an open state;

[0014] In the locked state, the locking mechanism is buckled on the convex block of the lifting platform, and the pressing kit presses the ball into the groove under the pressing action of the driving mechanism;

[0015] In the open state, the locking mechanism is disconnected from the lifting platform, and the driving mechanism drives the clamping kit to release the pressure on the ball.

[0016] Furthermore, the compression kit includes: a ball sleeve and a jacket pressing block, the jacket pressing block is sleeved on the upper end of the protrusion, and the ball sleeve is sleeved on the outside of the jacket pressing block;

[0017] In the locked state, the outer sleeve pressing block is pressed down by the driving mechanism to fix the ball sleeve on the protrusion;

[0018] In the open state, the outer sleeve pressure block moves upward to release the squeezing and fixing of the ball sleeve.

[0019] The driving mechanism includes a screw capping rod and an annular magnet sleeved on the bottom of the screw capping rod. When the screw capping rod is rotated downward, the annular magnet attracts the pressing assembly below to move upward and enter an open state.

[0020] Furthermore, the driving mechanism further comprises a compression spring, which is configured to always have a tendency to move the outer sleeve pressure block downward.

[0021] Among them, a plurality of balls are arranged in the ball sleeve, and the plurality of balls are evenly distributed in the ball square groove of the ball sleeve in a circular shape around the axis of the protrusion.

[0022] In the locked state, the ball is fixed in the groove of the protrusion by the ball sleeve. When the lifting platform is separated from the disassembly shell and attempts to release, the ball moves toward the narrowing part of the tapered end face to block the release.

[0023] At the same time, in the open state, the ball rises with the ball sleeve, and the ball moves toward the widening part of the end face of the tapered surface and leaves the groove on the protrusion.

[0024] It also includes a lifting mechanism, which is connected to the lifting platform. When the lifting mechanism is in operation, it can drive the lifting platform to move up and down;

[0025] The lifting platform rises or falls along the path provided by the lifting mechanism.

[0026] Furthermore, the lifting mechanism includes a screw rod, a fixed slider and a guide column; the screw rod is vertically arranged; the fixed slider is connected to the lifting platform; the guide column is parallel to the screw rod, and the guide column passes through the fixed slider.

[0027] It also includes a moisture-proof drainage device, which includes a drainage cylinder cover and a moisture-proof insulation layer;

[0028] The drainage cylinder cover is arranged outside the embedded well and is provided with a through hole for the mobile module to pass through; the moisture-proof insulation layer is arranged on the outside of the lifting mechanism.

[0029] Furthermore, a windproof sealing groove is provided between the drain cylinder cover and the disassembly and assembly shell, and a drainage groove is provided on the upper end surface of the drain cylinder cover.

[0030] The beneficial effects of the present invention are analyzed as follows:

[0031] The utility model discloses an easily disassembled pre-buried windproof charging pile, comprising a mobile module;

[0032] The mobile module includes a disassembly shell and a lifting platform;

[0036] The locking mechanism has a locked state and an open state;

[0037] In the locked state, the locking mechanism is buckled on the convex block of the lifting platform, and the pressing kit presses the ball into the groove under the pressing action of the driving mechanism;

[0038] In the open state, the locking mechanism is disconnected from the lifting platform, and the driving mechanism drives the clamping kit to release the pressure on the ball.

[0039] During daily use of the charging pile, the locking mechanism in the locked state fixes the disassembled shell on the lifting platform. When charging is required, the lifting mechanism is operated to move the lifting platform to the highest horizontal position, so that the entire charging device is exposed to the ground. Once it is in an idle state, the lifting mechanism is operated to move the lifting platform to the bottom, and the charging pile sinks into the pre-buried well; once disassembly and maintenance are required, the maintenance personnel operate the drive mechanism to release the locking state of the locking mechanism, and remove the disassembled shell from the lifting platform for separate maintenance work.

DETAILED DESCRIPTION

[0050] Example 1

[0051] This embodiment provides an easy-to-detach and pre-buried windproof charging pile. Please refer to Figures 1-6 , the charging pile includes a mobile module;

[0052] The mobile module includes a detachable housing 100 and a lifting platform 200;

[0053] A convex block 210 is provided on the top of the lifting platform 200, and a groove 211 is provided on the convex block 210;

[0054] The disassembly housing 100 is provided with a locking mechanism 110 and a driving mechanism 120;

[0055] The locking mechanism 110 includes a ball 111 and a pressing assembly that is engaged in the groove 211;

[0056] The locking mechanism 110 has a locked state and an open state;

[0057] In the locked state, the locking mechanism 110 is buckled onto the protrusion 210 of the lifting platform 200 , and the pressing assembly presses the ball 111 into the groove 211 under the pressing action of the driving mechanism 120 ;

[0058] In the open state, the locking mechanism 110 is disconnected from the lifting platform 200 , and the driving mechanism 120 drives the pressing assembly to release the pressure on the ball 111 .

[0059] During daily use of the charging pile, the locking mechanism 110 in a locked state fixes the disassembly shell 100 on the lifting platform 200. When charging is required, the lifting mechanism 300 operates to move the lifting platform 200 to the highest horizontal position, so that the entire charging device is exposed to the ground. Once in an idle state, the lifting mechanism 300 operates to move the lifting platform 200 to the bottom, and the charging pile sinks into the pre-buried well; once disassembly and maintenance are required, the maintenance personnel operate the driving mechanism 120 to release the locking state of the locking mechanism 110, and separate the disassembly shell 100 from the lifting platform 200 for separate maintenance work.

[0060] Therefore, the easily disassembled and pre-buried windproof charging pile provided by this solution can be flexibly disassembled and assembled through a locking mechanism, and maintenance personnel can replace or repair the charging pile device as appropriate.

[0061] In the optional scheme of this embodiment, it is more preferred that the locking mechanism 110 includes a clamping kit, which is sleeved on the protrusion 210. In order to better lock the ball 111 in the groove 211 of the protrusion 210, the clamping kit includes: a ball sleeve 111 and a jacket pressure block 112. The jacket pressure block 112 is sleeved on the upper end of the protrusion 210, and the ball sleeve 111 is sleeved on the outside of the jacket pressure block 112; in the locked state, the jacket pressure block 112 is pressed downward by the driving mechanism 120 to fix the ball sleeve 111 on the protrusion 210; in the open state, the jacket pressure block 112 moves upward to relax the squeezing and fixation of the ball sleeve 111. The ball sleeve 111 is a thin shell structure with multiple ball mounting grooves provided at the lower end. When the ball 111 is stuck in the protruding groove 211, the ball sleeve 111 is squeezed downward and fixed by the outer sleeve pressing block 112. At this time, the ball sleeve 111 restricts the ball 111 from moving in the vertical direction. The ball sleeve 111 and the outer sleeve pressing block 112 are made of magnetic materials and can attract each other with the annular magnet 122. The outer sleeve pressing block 112 is a conical pressing block. In the locked state, the conical surface of the outer sleeve pressing block 112 presses the ball sleeve 111. When the installation space is narrow, the pressing kit part can be appropriately reduced and the outer sleeve pressing block 112 can be changed to a conical ball sleeve pressing piece.

[0062] In an alternative embodiment of this embodiment, preferably, at least one ball 111 is disposed within the ball housing 111. The balls 111 are evenly distributed in a circular pattern around the axis of the projection within the ball groove of the ball housing 111. In the locked state, the balls 111 are secured within the groove 211 of the projection 210 by the ball housing 111. When the lifting platform 200 separates from the disassembly housing 100 and attempts to release, the balls 111 move toward the narrowing portion of the tapered end face, blocking the release. In the released state, the balls 111 rise with the ball housing 111, at which point they move toward the widening portion of the tapered end face, disengaging from the groove 211 of the projection.

[0063] In order to facilitate personnel operation, a driving mechanism 120 is provided above the locking mechanism 110 to control its unlocking. The driving mechanism 120 includes a capping screw 121 and an annular magnet 122 mounted on the bottom of the capping screw 121. When the capping screw 121 is screwed down, the annular magnet 122 attracts the clamping kit below to move upward and enter the open state. A circular cap is provided at the upper end of the cylindrical body of the capping screw 121, and a capping handle is also provided on the upper surface of the circular cap. The screw is provided with a thread to connect with the charging pile housing, and the annular magnet 122 is fixed to the lower end of the screw by a round nut. The annular magnet 122 can move freely in the vertical direction inside the charging pile housing. When the capping screw 121 is screwed up to a certain height, the lower end clamping kit must be able to break away from the attraction of the annular magnet 122 and return to the position when it was locked.

[0064] The drive mechanism 120 also includes a compression spring 123, which is configured to always have a tendency to move the outer cover pressing block 112 downward. The upper end of the compression spring 123 is set in the cylindrical groove of the charging pile housing, and the lower end is against the upper end surface of the outer cover pressing block 112.

[0065] To switch between pre-embedded storage and charging modes, the charging device also includes a lifting mechanism 300, which is connected to the lifting platform 200. When the lifting mechanism 300 is in operation, the lifting platform 200 moves up and down, and the lifting platform 120 rises or descends along the path provided by the lifting mechanism 300. The lifting platform 200 is generally driven by a screw mechanism, but can also be ejected using a spring and buffer mechanism. The latter is more practical when the charging pile is small and lightweight.

[0066] In the optional solution of this embodiment, it is more preferred that the lifting mechanism 300 includes a screw rod 310, a fixed slider 320, and a guide post 330; the screw rod 310 is arranged vertically; the fixed slider 320 is connected to the lifting platform 200; the guide post 330 is parallel to the screw rod 310, and the guide post 330 passes through the fixed slider 320. The screw rod 310, the guide post 330, and the horizontal plane of the lifting platform 200 on which the fixed slider 320 is installed are perpendicular to each other. In order to ensure that the lifting platform 200 always maintains stable operation during the ascent process, the cylindrical axis of the guide post 330 is parallel to the axis of the screw rod 310, and the mating surface between the fixed slider 320 and the guide post 330 needs to be lubricated with lubricating oil to maintain their unobstructed operation.

[0067] Because the entire device is buried in a pre-buried well underground for a long period of time, to protect it from the humid underground environment and maintain a dry and isolated operating environment, the device also includes a moisture-proof drainage device 400, which includes a drainage cylinder cover 410 and a moisture-proof insulation layer 420. The drainage cylinder cover 410 is installed outside the pre-buried well and is provided with a through hole for the mobile module to pass through. The moisture-proof insulation layer 420 is installed outside the lifting mechanism 300. This moisture-proof sealing structure preferentially blocks and diverts precipitation and sand from above to the outside of the device. At the same time, the multi-layer design of the moisture-proof insulation layer 420 prevents corrosive gases and liquids from passing through the moisture-proof insulation layer 420, forming a closed-loop protection for the entire space.

[0068] Due to the structural selection of the drain cylinder cover 410, a windproof sealing groove 411 is provided between the drain cylinder cover 410 and the disassembly and assembly shell 100, and a drainage groove 412 is provided on the upper end surface of the drain cylinder cover 410. Therefore, the drain cylinder cover 410 can effectively protect the charging pile in extreme environments such as wind, sand or rain.

[0069] Through the complementary nature of this composite structure, the easily disassembled and pre-buried windproof charging pile provided by this solution can not only reasonably utilize urban space for vehicle-to-grid interaction, adapt to the street environment, and not occupy street space, but also has the characteristics of being waterproof and windproof. It can also solve problems arising from long-term use such as subsequent maintenance and replacement with its advantage of being easy to disassemble and assemble.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the various embodiments of the present invention.
