Description

Technical Field

[0001] This invention relates to the field of robotics, and in particular to a charging station and a snow removal system. Background Technology

[0002] With the rapid development of robotics technology, robots are beginning to permeate every corner of our lives. Snow-sweeping robots, as a type of snow-sweeping robot, consist of a snow-sweeping device and a carrier used to move the device around the yard. The carrier is typically a wheeled or tracked self-propelled device. The snow-sweeping device mainly includes a snow-rolling mechanism and a snow-throwing mechanism. The snow-rolling mechanism gathers snow from the ground into a snow-rolling chamber, and then the snow-throwing mechanism throws the snow in the chamber in a designated direction.

[0003] In pursuit of low-carbon, environmentally friendly, energy-saving, and emission-reducing principles, traditional fuel-powered snow-clearing robots are gradually being phased out. Current snow-clearing robot development primarily utilizes battery-powered electric structures. The charging module is typically located at the rear or side of the vehicle, moving horizontally via a self-propelled device to approach the charging station for charging. Because snow-clearing robots usually clear snow while it's snowing, the charging module is easily covered by snowflakes or hardened with snow, leading to poor contact with the charging station and posing significant charging difficulties. Summary of the Invention

[0004] The present invention aims to provide a charging pile and a snow removal system, which can solve the technical problem of poor contact between the charging pile and the charging module in the prior art.

[0009] A lifting device is fixedly mounted on the base. The lifting device includes a lifting frame fixedly connected to the mounting plate and a power mechanism for driving the lifting frame.

[0010] In one possible embodiment of the charging pile of this application, the lifting device further includes a lifting platform, the lifting platform including at least a first cylinder at the top and a second cylinder at the bottom, the first cylinder being fixedly connected to the base, the lifting frame being disposed inside the lifting platform, the top of the lifting frame being connected to the first cylinder, and the first cylinder extending out or retracting into the second cylinder as the lifting frame rises and falls.

[0011] In one possible embodiment of the charging pile of this application, the top of the first cylinder is provided with a cover plate, the mounting plate is located below the cover plate, and the surface of the cover plate is provided with a second through hole for the conductive column to extend or retract.

[0012] In one possible embodiment of the charging pile of this application, a blocking block is provided on the inner wall of the first cylinder, and the mounting plate is located between the cover plate and the blocking block. The blocking block and the cover plate are arranged at a certain distance apart to form a space for the conductive column to retract into the first cylinder.

[0013] In one possible embodiment of the charging pile of this application, the lifting platform further includes at least one third cylinder connecting the first cylinder and the second cylinder, the bottom of the first cylinder is provided with a limiting block to restrict its exit from the third cylinder, and the top of the third cylinder is provided with a tapered edge corresponding to the limiting block.

[0014] In one possible embodiment of the charging pile of this application, a buffer pad is also provided between the edge sealing and the limiting block.

[0015] In one possible embodiment of the charging pile in this application, the lifting frame is a scissor-type lifting frame.

[0016] In one possible embodiment of the charging pile of this application, the charging pile includes a power supply component, and the conductive post is electrically connected to the power supply component for electrical contact with the charging electrodes of the other end device; the surface of the mounting plate is provided with a mounting position for fixing the conductive post, the mounting position being adapted to the conductive post so that the conductive post has a certain size of expansion and contraction space in a direction perpendicular to the mounting plate; the charging module also includes a reset component, the reset component being disposed between the conductive post and the mounting plate, for providing the upward rebound force required when the conductive post expands and contracts relative to the mounting base.

[0017] In one possible embodiment of the charging pile of this application, the reset member is a spring, the surface of the mounting plate is provided with a first through hole through which the bottom of the conductive post can pass, the spring is sleeved on the conductive post, the top of the conductive post is provided with a post cap that abuts against the spring, and the bottom of the conductive post is provided with a blocking part for preventing the conductive post from popping out of the first through hole. This application also discloses a snow removal system, including:

[0018] The charging piles mentioned above;

[0019] The self-propelled device has a charging module at its bottom, and the charging module has charging electrodes that are compatible with the conductive post.

[0020] In one possible embodiment of the snow removal system of this application, the charging module is provided with a housing, and the surface of the housing is provided with a charging port for the charging electrode to be exposed.

[0022] In one possible embodiment of the snow removal system of this application, the surface area of ​​the charging electrode is larger than that of the conductive post.

[0023] The charging pile and snow removal system disclosed in this application achieve close contact between the conductive column and the charging electrode through the elastic expansion and contraction of the conductive column relative to the mounting plate, reducing the precision requirements and ensuring continuous charging. The charging plate is raised and lowered relative to the lifting platform through the lifting frame, so that the conductive column can be retracted into the lifting platform when not charging, avoiding exposure to the outside for contamination and corrosion. The snow removal system ensures good contact between the conductive column and the charging electrode through the matching of the charging pile and the charging electrode. Furthermore, during charging, the conductive column pushes the charging electrode into the charging port, thereby detaching ice or snow from the charging electrode and achieving the effect of breaking up the ice or snow.

[0051] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0052] The snow removal system disclosed in this application includes, for example: Figures 1-3 The charging pile 100 shown, and as shown Figure 7 The snow-sweeping robot 5 shown is, for example Figures 9-10 As shown, the snow-sweeping robot 5 has a charging module 200 at the bottom of its self-propelled device. Among other things, as... Figures 1-3 As shown, the charging pile 100 includes a base 1, a charging module 2 disposed on the base 1, and a lifting device 3 located within the base 1. The charging module 200 is provided with charging electrodes 6. The charging module 2 includes conductive posts 20 and a mounting plate 21 for fixing the conductive posts 20. The conductive posts 20 are electrically connected to the power supply component. In this embodiment, the charging pile 100 controls the lifting of the charging module 2 through the lifting device 3. During charging, it can actively pierce snow or ice blocks on the surface of the charging module 200 to facilitate charging. At the same time, it facilitates the snow-sweeping robot 5 to place the charging module 200 at the bottom, changing the traditional side charging to bottom-up charging of the snow-sweeping robot 5, avoiding charging failure caused by the charging module 200 being exposed to the external environment and resulting in icing or snow accumulation.

[0053] Existing charging modules are mainly installed on the surface of the self-propelled vehicle. Before charging, the vehicle and charging pile need to be positioned. Due to positioning accuracy errors, poor contact often occurs between the conductive posts of the charging pile and the charging electrodes of the self-propelled vehicle, resulting in intermittent charging. To solve this problem, the surface of the mounting plate 21 has mounting positions for conductive posts 20, which can extend and retract within a certain range relative to the mounting plate 21. A reset component is also provided between the conductive posts 20 and the mounting plate 21. When the conductive posts 20 are pressed against the surface of the charging electrodes, they retract into the mounting plate 21 by a certain distance. Due to the action of the reset component, the charging posts 20 maintain an upward restoring force, thus maintaining a tight fit with the charging electrodes.

[0054] In this embodiment, the conductive post 20 extends and retracts relative to the mounting plate 21 within a certain range, and the reset component provides the restoring force required for the conductive post 20 to spring upward, so that when the conductive post 20 is in the charging state, it always abuts against the surface of the charging electrode and maintains electrical contact with the charging electrode. The contact surfaces of the two are tightly fitted, ensuring good electrical contact.

[0055] Specifically, such as Figures 4-5As shown, the reset component is a spring 201, which is a compression spring sleeved on the surface of the conductive post 20. The surface of the mounting plate 21 is provided with a first through hole 210. The tail of the conductive post 20 can pass through the first through hole 210 and perform vertical extension and retraction within a certain range within the first through hole 210. The end of the conductive post 20 is provided with a post cap 202, and the tail of the conductive post 20 is provided with a blocking part to prevent it from disengaging from the first through hole 210. In this embodiment, the blocking part is a limiting nut 203 that is detachably connected to the bottom of the conductive post 20. In other embodiments of this application, the blocking part can also be a snap ring or other detachable limiting structure. The dimensions of the post cap 202 and the limiting nut 203 are both larger than the first through hole 210. The top end of the spring 201 abuts against the post cap 202, and the bottom end abuts against the mounting plate 21. When the conductive post 20 is subjected to pressure, it retracts downward into the mounting plate 21. When the pressure is removed, the conductive post 20 rebounds upward. The maximum compressible elastic deformation of spring 201 is the maximum extension and retraction stroke of conductive post 20.

[0056] Thus, this embodiment uses the simplest structure to achieve the retractable movement of the conductive post 20 relative to the mounting plate 21, and uses a low-cost and easy-to-install spring 201 as a reset component, thereby reducing the production cost and failure rate of the product.

[0057] Furthermore, such as Figure 4 and Figure 5 As shown, the power supply assembly includes a terminal block 23, which is fixedly connected to the conductive post 20 via a limiting nut 203, thereby achieving electrical connection between the power supply assembly and the conductive post 20. To improve space utilization, a fixing plate 24 is provided at the bottom of the mounting plate 21. The fixing plate 24 has a limiting hole 25 with an inner diameter smaller than the first through hole 210. The limiting hole 25 allows the conductive post 20 to pass through but restricts the spring 201 from passing through, while the first through hole 210 allows the spring 201 to pass through. In this way, the bottom end of the spring 201 indirectly abuts against the mounting plate 21 by abutting against the fixing plate 24. With this structural arrangement, the portion of the spring floating on the surface of the mounting plate 21 is shorter, reducing its space occupation and improving space utilization.

[0058] like Figure 3 As shown, the charging module 2 is located at the center of the charging pile 100, and the lifting device 3 is located inside the charging pile 100 and below the charging module 2. Specifically, the lifting device 3 includes a lifting frame 30 and a power mechanism for driving the lifting frame 30 to perform lifting actions. The top of the lifting frame 30 is fixedly connected to the mounting plate 21, and the mounting plate 21 is switched between the charging position and the storage position by lifting the lifting frame 30. The base 1 is a platform for parking the snow sweeping robot when charging. The charging pile 100 is also equipped with a positioning device, which communicates with the snow sweeping robot to allow the snow sweeping robot to park directly above the charging module 2.

[0059] In this way, the position of the mounting plate 21 is changed by the lifting frame 30. In the charging state, the lifting frame 30 drives the mounting plate 21 to rise until it comes into contact with the charging electrode of the snow sweeping robot, thereby completing the electrical connection with the other end device. After charging is completed, the lifting frame 30 drives the mounting plate 21 to fall, so that the mounting plate 21 is stored in the charging pile 100.

[0060] Because the snow-sweeping robot's working environment exposes the charging station outdoors for extended periods, the conductive posts 20 are highly susceptible to dirt buildup, leading to oxidation and corrosion. To address this technical issue, such as... Figures 1-3 As shown, the charging pile 100 also includes a lifting platform 4, which includes at least a first cylinder 41 and a second cylinder 42. The second cylinder 42 is disposed at the bottom of the base 1 and fixedly connected to the base 1, and the first cylinder 41 is fitted inside the second cylinder 42. The lifting frame 30 and the mounting plate 21 are disposed inside the lifting platform 4, and the top of the lifting frame 30 is connected to the top of the first cylinder 41. When the lifting frame 30 rises, it drives the first cylinder 41 to extend upward; when the lifting frame 30 descends, the first cylinder 41 retracts into the second cylinder 42.

[0061] In this way, a relatively enclosed space is formed inside the lifting platform 4, and the mounting plate 21 and the lifting device 3 are placed inside the lifting platform 4, so that the mounting plate 21 and the lifting device 3 are isolated from the external environment, avoiding the corrosion and pollution of the equipment caused by exposure to the outdoor environment.

[0062] Specifically, such as Figures 1-3 As shown, the top of the first cylinder 41 is provided with a cover plate 44, and the mounting plate 21 is located below the cover plate 44. The surface of the cover plate 44 is provided with a second through hole 420 through which the top of the conductive post 20 can pass. As the mounting plate 21 rises or falls, the top of the conductive post 20 can extend or retract into the second through hole 420. When the conductive post 20 retracts into the second through hole 420, the entire charging module 2 is stored inside the lifting platform 4, achieving isolation from the external environment.

[0063] like Figure 3 As shown, the inner wall of the first cylinder 41 is provided with a blocking block 410, which extends radially along the inner wall to the trajectory of the mounting plate 21 as it rises and falls. Thus, when the mounting plate 21 descends, it contacts the blocking block 410, causing the first cylinder 41 to retract along with the mounting plate 21 into the second cylinder 42. There is a certain gap between the blocking block 410 and the cover plate 44, which is greater than the length of the conductive post 20. Therefore, when the mounting plate 21 descends, it needs to travel a certain distance without contacting the blocking block 410. When the mounting plate 21 contacts the blocking block 410, the conductive post 20 has already retracted below the cover plate 44. The mounting plate 21 continues to descend under the action of the lifting frame 30, at which point it indirectly causes the first cylinder 41 to retract into the second cylinder 42.

[0064] In this way, the lifting platform 4 is controlled by the blocking block 410. At the same time, the blocking block 410 and the cover plate 44 are set at intervals to reserve sufficient space for the conductive column 20 to retract into the lifting platform 4. This ensures that after each charging is completed, as the lifting platform 4 descends, the conductive column 20 first retracts into the first cylinder 41, which protects the conductive column 20.

[0065] like Figures 2-3 As shown, the lifting platform 4 also includes at least one third cylinder 43, which is connected between the first cylinder 41 and the second cylinder 42. The number of third cylinders 43 determines the lifting stroke of the lifting platform 4. A limiting block 411 is provided at the bottom of the first cylinder 41, and a tapered edge 430 is provided at the top of the third cylinder 43, which is fitted onto the first cylinder 41. The tapered edge 430 blocks the limiting block 411 from passing through. Therefore, the combination of the limiting block 411 and the tapered edge 430 ensures that the first cylinder 41 will not detach from the third cylinder 43 when it rises, thus providing a limiting function. To prevent wear caused by a hard collision between the limiting block 411 and the tapered edge 430 when the lifting platform 4 extends, a buffer pad 45 is also provided between the tapered edge 430 and the limiting block 411. The buffer pad 45 serves to isolate and buffer the limiting block 411 and the shrinking edge 430. At the same time, the buffer pad 45 also increases the friction between the outer wall of the first cylinder 41 and the inner wall of the third cylinder 43, so that a damping effect is formed between the cylinders during the rising and falling of the lifting platform 4, which increases the stability of the equipment and eliminates noise.

[0066] like Figures 4-6 As shown, the lifting frame 30 in this embodiment adopts a scissor-type lifting structure. A push rod 31 is provided at the bottom of the lifting frame 30 as the power mechanism for lifting the lifting frame 30. The lifting of the lifting frame is controlled by the extension and retraction of the push rod 30. The push rod 31 can be a hydraulic or pneumatic push rod. A base 10 is provided at the bottom of the base 1, and the lifting frame 30 is located on the base 10.

[0067] The top side of the lifting frame 30 is hinged to the mounting plate 21, and the other side is movably connected to the bottom of the mounting plate 21 via a pulley 32. To prevent the mounting plate 21 from shaking due to vibration or vibration during equipment operation, a limiting plate 22 is also provided at the bottom of the mounting plate 21 on this side in this embodiment. The limiting plate 22 is located at the bottom of the pulley 32. When the mounting plate 21 on the side of the pulley 32 tends to jump or flip, the limiting plate 22 will act on the bottom of the pulley 32 to prevent the mounting plate 21 from detaching from the pulley 32, thereby fixing the mounting plate 21.

[0068] The snow-sweeping robot 5 in this embodiment, such as Figures 7-8As shown, the device includes a snow removal device 50 and a self-propelled device 51 for supporting the snow removal device 50 and enabling it to move and operate, as well as a charging module 200 disposed on the self-propelled device 51. The self-propelled device 51 includes a chassis 52 for supporting a battery and the charging module 200. The charging module 200 is used to charge the battery and is disposed at the bottom of the self-propelled device 51, that is, at the bottom of the chassis 52. The chassis 52 has a first mounting position for installing the battery and a second mounting position for installing the charging module 200.

[0069] like Figures 9-10 As shown, in this embodiment, the charging module 200 includes an electrode assembly fixed to the lower surface of the chassis 52. The electrode assembly includes a charging electrode electrically connected to the battery via a charging circuit. The charging electrode is movably connected to the bottom of the self-propelled device 51, and has a retractable position and an extended position during its movement. When in the retractable position, the charging electrode retracts into the self-propelled device 51; when in the extended position, the charging electrode extends out of or is flush with the surface of the chassis 52. The retractable position corresponds to the location of the charging electrode during charging, and the extended position corresponds to the location of the charging electrode during non-charging.

[0070] like Figure 9 and Figure 10 As shown, in this embodiment, the charging electrode is a conductive disk 6, with two conductive disks 6 spaced apart. The conductive disk 6 is disc-shaped with a radial dimension much larger than its axial dimension, making the area of ​​the conductive disk 6 larger than that of the conductive post 20. Compared with the traditional socket plug structure, this increases the contact area for docking with the conductive post 20, allowing electrical connection to be achieved simply by having a contact point between the conductive post 20 and the conductive disk 6, thus reducing the requirements for the positioning accuracy of the self-propelled device 51 and the charging pile 100 during charging.

[0071] The charging circuit includes a rectifier bridge, filter circuit, transformer, etc. The voltage is rectified, filtered, and stepped down by the charging circuit before being input to the battery for charging. It should be understood that in specific embodiments, the parameters of various components in the charging circuit need to be adjusted according to different power and voltage output requirements. The charging circuit is a common technology in the field of electrical engineering and will not be described in detail here.

[0072] With this mechanism design, the conductive disk 6 is in an extended position when not charging, that is, flush with or protruding from the bottom surface of the self-propelled device 51. When there are clumps (frost, snow, or ice) on the surface of the conductive disk 6, the conductive post 20 will rise and support the conductive disk 6 during charging. Therefore, the conductive disk 6 will be supported by the conductive post 20 and retract into the self-propelled device 51. As the conductive disk 6 retracts, the clumps on the surface of the conductive disk 6 are blocked by the chassis 20, which causes greater stress inside the clumps. This causes them to break due to mutual compression and detach from the chassis 52 and the conductive disk 6. This ensures normal contact between the conductive disk 6 and the conductive post 20, and completes the charging process.

[0073] like Figures 4-6 As shown, in order to enable the conductive post 20 to pass through the agglomerate and contact the conductive disk 6, the top of the conductive post 20 is set to be conical in this embodiment to improve the ice-breaking ability of the conductive post 20.

[0074] Furthermore, in this embodiment, as Figure 10 As shown, to reset the conductive disk 6 from its retracted position to its extended position, the electrode assembly also includes a reset mechanism. In this embodiment, the reset mechanism includes an elastic element that acts on the conductive disk 6 to provide the restoring force required for its reset. This elastic element is a spring, specifically a compression spring 61 that abuts against the top surface of the conductive disk 6. When the conductive post 20 presses the conductive disk 6 upward, the compression spring 61 begins to compress and store energy. After charging is completed, the compression spring 61 releases its elastic potential energy and pushes the conductive disk 6 downward, causing the conductive disk 6 to disengage from the conductive post 20, thereby completing the reset from the retracted position to the extended position.

[0075] Multiple compression springs 61 are arranged around the geometric center of the conductive disk 6. In this embodiment, the conductive disk 6 is a circular metal disk, and four compression springs 61 are arranged at equal intervals on the same circumference around the center of the conductive disk 6.

[0076] like Figures 10-12 As shown, the charging module 200 also includes a housing 7 fixed to the bottom of the self-propelled device 2, and the electrode assembly is housed inside the housing 7. The electrode assembly also includes a cover 71 disposed within the housing 7, with a receiving cavity 72 formed inside the cover 71. The conductive disk 6 is housed within the receiving cavity 72 and can reciprocate within it. An opening 73 is provided at the bottom of the cover 71 (the end facing downwards from the self-propelled device 2) for the conductive disk 6 to pass through, and the opening 73 communicates with the receiving cavity 72. The reciprocating movement of the conductive disk 6 within the receiving cavity 72 allows it to switch between a retracted position and an extended position.

[0077] like Figure 10 As shown, the bottom of the housing 7 has a charging port 74 corresponding to the opening 73. After charging is finished, the conductive disk 6 extends through the opening 73 and out of the surface of the housing 7 or is flush with the surface of the housing 7 under the action of the compression spring 61.

[0078] Furthermore, such as Figure 10 As shown, the compression spring 61 is disposed between the cover 71 and the conductive disk 6. The cover 71 is also provided with a guide member, which is used to restrict the degree of freedom of the conductive disk 6 in the direction perpendicular to the extension and retraction direction, so that the conductive disk 6 can only move along the direction defined by the guide member. The guide member is a guide rod 62, one end of which is fixedly connected to the conductive disk 6, and the other end is movably connected to the cover 71.

[0079] Specifically, such as Figures 10-12 As shown, the top of the cover 71 has a guide hole 710 for the middle part of the guide rod 62 to pass through, as... Figure 14 As shown, the other end of the guide rod 62 located outside the cover 71 is provided with a tailstock 620. The guide hole 710 allows the middle part of the guide rod 62 to pass freely, but restricts the passage of the tailstock 620. The end of the guide rod 62 passes through the cover 71 and is threadedly connected to the conductive disk 6, so that the guide rod 62 can move relative to the cover 71 with the conductive disk guide 6. Limiting components are also fixed on the guide rod 62, such as... Figure 13 As shown, the limiting component is a retaining ring 63 sleeved on the surface of the guide rod 62. Of course, in other embodiments of this application, the retaining ring 63 can also be disposed on the surface of the conductive disk 6. When the conductive disk 6 is in the outward position, the tailstock 620 contacts the top surface of the cover 71, restricting the conductive disk 6 from moving further downward. At this time, the conductive disk 6 reaches the limit position of the outward position. When the conductive post 20 pushes the conductive disk 6 upward to switch it from the outward position to the retracted position, the guide rod 62 moves upward through the guide hole 710. When the retaining ring 63 contacts the top of the cover 71, the conductive disk 6 retracts to the limit position.

[0080] Therefore, in this example, the guide rod 62 serves not only as a guide but also as a connector between the cover 71 and the conductive disk 6. For example... Figure 10 As shown, the inner surface of the top of the cover 71 is provided with a positioning post 75 for fixing the compression spring 61, and the positioning post 75 passes through the top of the compression spring 61. Figure 12 As shown, the upper surface of the conductive disk 6 is provided with four positioning grooves 76 for fixing the compression spring 61, and correspondingly, the inner surface of the top of the cover 71 is provided with four positioning posts 75.

[0081] like Figures 11-12 As shown, the cover 71 has fixing ears 77 on both sides, and the cover 71 is fixedly connected to the housing 7 through the fixing ears 77. The conductive disk 6 has a terminal 66 for fixing the electrode lead terminal 65 at the center. The cover 71 has a lead hole 78 on the top, and the lead terminal 65 is located in the lead hole 78 and is connected to the charging circuit in the self-propelled device 51 through the lead hole 78.

[0082] In this embodiment, the reset mechanism not only resets the conductive disk 6 from the storage position to the outward extension position, but the elastic element also ensures that the conductive disk 6 always remains in close contact with the conductive post 20, thus ensuring the continuous charging operation.

[0083] Furthermore, such as Figure 9 As shown, the electrode assembly includes two conductive disks 6 arranged side by side, with a blocking portion 64 between the two conductive disks 6. The blocking portion 64 remains relatively stationary with respect to the self-propelled device 51. Specifically, the blocking portion 64 is formed on the housing 7 in the portion located between the two charging ports 74. In the non-charging state, the conductive disk 6 is in the outward position. When there is a block (ice, snow, or frost) on the end face of the conductive disk 6 and the surface of the housing 7, the two ends of the block will be subjected to an upward pulling force from the conductive disk 6 as the conductive disk 6 moves from the outward position to the retracted position. Due to the obstruction of the blocking part 64, the block is subjected to both the normal stress caused by the bending moment and the shear stress applied by the blocking part 64. Even if the block is a thick ice block, it will break under the action of the blocking part 64 under the action of the shear stress. The two small pieces of ice will continue to break under the action of the continuously generated normal stress (during the movement of the conductive disk 6 from the outward position to the retracted position), thereby eliminating the problem of the conductive disk 60 being unable to complete charging due to ice on its surface.

[0084] When the conductive disk 6 is in the extended position, the surface of the blocking part 64 is flush with or protrudes from the bottom end face (lower surface) of the conductive disk 6. That is, the end face of the blocking part 64 cannot be higher than the bottom end face of the conductive disk 6 in the vertical direction. In this way, when the conductive disk 6 retracts, the blocking part 64 causes shear stress to be generated inside the agglomerate, thereby breaking the agglomerate.

[0085] The charging module, charging pile, and snow removal system disclosed in this application achieve close contact between the conductive column and the charging electrode through the elastic expansion and contraction of the conductive column relative to the mounting plate, reducing the precision requirements and ensuring continuous charging. The charging plate is raised and lowered relative to the lifting platform through a lifting frame, allowing the conductive column to retract into the lifting platform when not charging, avoiding exposure to the outside for contamination and corrosion. The snow removal system ensures good contact between the conductive column and the charging electrode through the matching of the charging pile and the charging electrode. Furthermore, during charging, the conductive column pushes the charging electrode into the charging port, thereby detaching ice or snow from the charging electrode and achieving the effect of breaking up the ice or snow.
