Description

Technical Field

[0001] The present invention relates to a charging pile, and in particular to a modular combined high-efficiency energy-saving charging pile. Background Art

[0002] To accommodate the development of the new energy industry, the widespread use of charging piles has emerged. This can promote the widespread adoption of electric vehicles and, in turn, drive the coordinated development of related new energy industries such as battery technology and smart grids. Modular charging piles consist of multiple modules with distinct functions. Each module is connected via standardized interfaces, allowing for flexible configuration, expansion, or replacement based on actual needs. However, existing modular charging piles present several issues during use. First, while standardized interfaces are used for electrical connections between modules, this also makes it difficult to distinguish between connecting cables. This is particularly true when replacing a module, as the numerous interfaces and cables can easily lead to confusion, reducing maintenance efficiency. Second, the control circuits (including their internal electrical components, collectively referred to as control circuits) are more centralized within each functional module, resulting in increased weight. Traditional bolts and nuts, when used for fastening, are numerous and inconvenient, making them difficult to handle during installation and removal, reducing maintenance efficiency. Finally, traditional photovoltaic power generation systems, designed to achieve energy conservation, are susceptible to dust obstruction and high temperatures, resulting in reduced power generation and rapid loss, making them inefficient. This highlights the shortcomings of existing technologies. Summary of the Invention

[0008] On the basis of the above technical solution, the power distribution module, the power conversion module and the output control module are detachably electrically connected through a connecting cable. The connecting cable includes a cable body and a cable plug. The two ends of the cable body are fixed and electrically connected to the cable plug. The cable body includes a conductor therein and an insulating layer wrapped on the outside. The cable plug includes a plug board and a support part. The support part made of insulating material wraps and fixes the rear part of the plug board. The plug board made of conductive material is electrically connected to the conductor. The housings of the power distribution module, the power conversion module and the output control module are respectively fixed with control circuits that realize corresponding functions.

[0011] On the basis of the above technical solution, the right rear portion of the box body is hinged with multiple positioning plates made of transparent material, and the virtual hinge axis of each positioning plate is vertically arranged. A fastening bolt is inserted through the left part of each positioning plate, and multiple fastening seats are fixed to the left end of the rear wall of the box body.

When the contact protrusion is in fit and contact with the contact groove and the No. 3 compression spring does not deform, the front end of the pressing tube just contacts the rear end of the plug tube. When the screw ring moves forward, it can push the plug tube forward by squeezing the No. 3 compression spring.

When the No. 1 support shaft rotates, the cleaning roller can also be used to clean the surface of the photovoltaic panel, thereby improving the power generation efficiency. When it rains, the upper opening of the water collection tank is made to face upward, so that rainwater can be collected to wet the cleaning roller. Then, when the No. 1 support shaft rotates again, the wet cleaning roller can be used to clean the photovoltaic panel, thereby improving the cleaning effect and improving the power generation efficiency. By controlling the support frame to assume a forward horizontal posture, the front protrusions can be moved closer to or farther from each other by pulling and releasing the handle, thereby releasing and restoring the contact between the contact groove and the support frame, thereby realizing the replacement of the power distribution module, power conversion module, and output control module. The device is easy to hold and maintain, thereby improving maintenance efficiency. By utilizing the cooperation between the supporting portion, the toggle rod and the positioning hole, the position of the cable plug relative to the positioning plate can be limited, which is not easy to be confused during maintenance and is easy to distinguish, thereby improving maintenance efficiency.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-9 As shown, a modular combined high-efficiency energy-saving charging pile includes a box body 1, in which a power distribution module, a power conversion module, an output control module and a controller 5 electrically connected to each other are installed, and the left and right parts are each penetrated with an external heat dissipation slot 6, and the power distribution module is electrically connected to the external power grid. It is characterized in that: the power distribution module, the power conversion module, and the output control module all include a shell 7, and the output control module is also electrically connected to a charging line 8. The shell 7 is penetrated with an internal heat dissipation slot 9 for ventilation, and the inside is respectively fixed with The cooling fan has a support groove 11 fixed on the top of the box body 1, and a guide rail 12 is fixed on the left and right ends of the inner wall of the support groove 11 along the up and down directions, and a drain pipe 13 is fixed on the rear lower part. The two guide rails 12 corresponding to each other on the left and right are a group, and each group of the guide rails 12 is connected to the slider 72 for sliding up and down. Each group of the guide rails 12 is connected to the slider 72 for sliding as a group, and each group of the sliders 72 is connected to the cleaning roller 14 for rotating in the left and right horizontal directions. The bottom ends of the sliders 72 are fixed to the bottom ends of the inner walls of the support groove 11. Compression spring 15, the support groove 11 is connected to a plurality of No. 1 support shafts 16 and No. 2 support shafts 17 in rotation from front to back, the left and right parts of the No. 1 support shaft 16 are coaxially fixed with a No. 1 gear 18, and an opaque and white water collection tank 19 is fixed axially in the middle, the left and right parts of the No. 2 support shaft 17 are coaxially fixed with a No. 2 gear 20, the water collection tank 19 is a triangular prism with a large upper opening and a small bottom opening, and a photovoltaic panel 21 is fixed at the front end, the cleaning roller 14 is on the main compression spring 15 Under the indirect push of , it can move upward and fit in contact with the outer wall of the water collecting tank 19 and the outer wall of the photovoltaic panel 21. The No. 1 gear 18 is engaged with the No. 2 gear 20. A reduction motor 22 with a braking function is fixed to the rear part of the support groove 11. The rotating shaft of the reduction motor 22 is connected to the No. 2 support shaft 17 through a bevel gear. The photovoltaic panel 21, the reduction motor 22 and the controller 5 are electrically connected. The controller 5 is electrically connected to the output control module. The controller 5 is a known prior art, such as a single-chip microcomputer.

[0025] When in use, the front or rear end of the box body 1 is made to face the sun, and the box body 1 is electrically connected to the external power grid through the power distribution module. The power conversion module is then used to convert the electric energy, and then the electric energy is output through the output control module and the charging line 8. The electric energy generated by the photovoltaic panel 21 is processed by the controller 5 and supplied to the cooling fan for use. When the cooling fan has no photovoltaic power supply, it consumes the electric energy of the power grid to work. The reduction motor 22 is controlled to rotate, and the bevel gear, the first gear 18 and the second gear 20 can make the first support shaft 16 and the second support shaft 17 rotate, so that the angle of the photovoltaic panel 21 relative to the box body 1 can be adjusted. When the photovoltaic panel 21 faces the sun directly, it can generate electricity normally. When it is hot at noon and the sunlight is strong, the reduction motor 22 is controlled to rotate. It rotates so that the rear part of the water collecting tank 19 faces the sun, which can prevent the photovoltaic panel 21 from being directly exposed to the sunlight, thereby achieving the protection effect of the photovoltaic panel 21 and reducing losses. During the rotation of the No. 1 support shaft 16, the cleaning roller 14 is affected by the elastic repulsive force of the main compression spring 15, which can make the cleaning roller 14 fit with the photovoltaic panel 21 or the outer wall of the water collecting tank 19. By controlling the reduction motor 22 to rotate appropriately, the cleaning roller 14 can be used to clean the surface of the photovoltaic panel 21, thereby improving the power generation efficiency. When it rains, by controlling the reduction motor 22 to rotate appropriately, the upper opening of the water collecting tank 19 is upward, and rainwater can be collected to moisten the cleaning roller 14. Then, when the No. 1 support shaft 16 rotates again, the wet cleaning roller 14 can be used to clean the photovoltaic panel 21, thereby improving the cleaning effect and improving the power generation efficiency.

[0026] The box body 1 is penetrated from front to back, and a plurality of vertical support legs 23 are fixed to the bottom end. The front of the box body 1 is hinged with a front box door 24 that can be covered, and the rear is hinged with a rear box door 25 that can be covered. The virtual hinge axes of the front box door 24 and the rear box door 25 are vertically arranged, and are locked with the box body 1 by locks to maintain the covered state. The external heat dissipation slots 6 on the left and right parts of the box body 1 are inclined outward and downward, and a support frame 26 is fixed at each end of the left and right inner wall of the box body 1. Each of the support frames 26 is respectively connected with a filter 27 in the front and back, and each of the filters 27 together covers the external heat dissipation slot 6. The front box door 24 is fixed with a human-machine interaction panel 28 and a placement seat 29. The human-machine interaction panel 28 is electrically connected to the output control module. The other end of the charging cable 8 is electrically connected and fixed with a charging gun. The placement seat 29 is used to plug and place the charging gun. The outer circumference of the cleaning roller 14 is made of sponge or a brush.

[0027] Human-computer interaction is performed through the human-computer interaction panel 28 to perform charging operations.

[0028] The inner wall of the box body 1 is fixed with multiple No. 3 support shafts 31 along the left and right directions, and each of the No. 3 support shafts 31 is arranged in sequence from top to bottom, and each of the No. 3 support shafts 31 is coaxially connected to a support cylinder 32, and each of the left and right parts of each support cylinder 32 is coaxially fixed with a worm gear 33, and a support frame 34 is radially fixed thereto, and the support frame 34 is tightly installed with the shell 7, and the left and right parts of the shell 7 are each installed with a handle 35, and the handle 35 protrudes backward from the rear end of the shell 7, and multiple brackets 36 are fixed to the left and right ends of the inner wall of the box body 1, and the brackets 36 corresponding to each other tilted front and back are a group, and each group of the brackets 36 are rotatably connected to the No. 4 support Shaft 37, four supporting shafts 37 corresponding to each other on the left and right are a group, each of the four supporting shafts 37 is coaxially fixed with a worm 38, the worm 38 is meshed with the worm wheel 33, and a plurality of servo motors 39 are fixed in sequence from top to bottom on the right end of the box body 1, and the rotating shafts of each of the servo motors 39 are coaxially fixed with the fifth supporting shaft 40, and are electrically connected to the controller 5 respectively, and each of the fifth supporting shafts 40 is respectively rotatably connected to the box body 1 in the left and right horizontal directions, and is coaxially rotatably connected to the second bevel gear 41, and each of the four supporting shafts 37 is coaxially fixed with the first bevel gear 42, and the second bevel gear 41 is meshed with the first bevel gear 42.

[0029] During use, by controlling the corresponding servo motor 39 to rotate forward and backward, the support tube 32 and the support frame 34 can be swung back and forth with the support shaft 31 as the axis by using the second bevel gear 41, the fifth support shaft 40, the first bevel gear 42, the fourth support shaft 37, the worm 38 and the worm gear 33. When the support frame 34 is vertically upward, charging can be carried out normally. When the support frame 34 is horizontally facing forward, the distribution module, the power conversion module and the output control module can be conveniently moved by the carrying handle 35.

[0030] The left and right parts of the support frame 34 are in the shape of vertical round rods and are plugged into the shell 7 front and back. The left and right parts of the shell 7 are each fixed with a horizontally protruding rear bump 43. The left and right parts of the shell 7 are each slidably connected with a front bump 44. The front bump 44 is located in front of the rear bump 43. The front bump 44 and the rear bump 43 are respectively provided with a contact groove 45. The contact groove 45 fits with the round rod structure of the support frame 34. The handle 35 is slidably connected to the shell 7 front and back. A vertical guide rod 46 is respectively fixed to the front of each handle 35, and a tension spring 47 is fixed to the front end of each handle 35. 44 is respectively penetrated by guide grooves 48 on the upper and lower sides. The guide grooves 48 on the left and right sides of the shell 7 are in a forward-converging shape. The guide grooves 48 are slidably connected to the guide rods 46. The front protrusion 44 has a tendency to move forward under the elastic tension of the tension spring 47, and the contact groove 45 of the front protrusion 44 is pushed toward the round rod-shaped structure of the support frame 34 through the guide rod 46 and the guide groove 48 to move and fit. When the handle 35 is pulled backward to a certain position, the sliding connection between the guide grooves 48 and the guide rods 46 can make the two front protrusions 44 on the left and right parts of the shell 7 approach each other and completely separate from the round rod-shaped structure of the support frame 34.

[0031] Furthermore, when it is necessary to disassemble the power distribution module, power conversion module and output control module, the control support frame 34 is controlled to move forward horizontally, and the lifting handle 35 is manually pulled upward to cause the tension spring 47 to undergo elastic deformation. At the same time, the cooperation between the guide rod 46 and the guide groove 48 makes the front protrusions 44 on the left and right parts of the shell 7 approach each other, so that the contact groove 45 is away from the support frame 34 and completely disengaged. At this time, the corresponding power distribution module, power conversion module and output control module can be lifted up and removed from the support frame 34. When placing, it is only necessary to manually lift the lifting handle 35 and place it in the support frame 34, so that the contact groove 45 of the rear protrusion 43 can first be in contact with the support frame 34, and then the lifting handle 35 is completely released. The front protrusion 44 can be reset under the elastic repulsive force of the tension spring 47, that is, the contact groove 45 of the front protrusion 44 can be in contact with the support frame 34, thereby realizing the limited installation of the power distribution module, power conversion module and output control module, which is convenient and fast, and improves maintenance efficiency.

[0032] The power distribution module, power conversion module, and output control module are detachably electrically connected via a connecting cable. The connecting cable includes a cable body 74 and a cable plug. The two ends of the cable body 74 are fixed and electrically connected to the cable plug. The cable body 74 includes a conductor therein and an insulating layer wrapped around the outside. The cable plug includes a plug board 50 and a support portion 51. The support portion 51 made of insulating material wraps and fixes the rear part of the plug board 50. The plug board 50 made of conductive material is electrically connected to the conductor. The housings 7 of the power distribution module, power conversion module, and output control module are respectively fixed with control circuits that realize corresponding functions. The rear part of the housing 7 is fixed with a socket 52 for plugging in to the plug board 50. The socket 52 is made of conductive material and is electrically connected to the control circuit in the housing 7.

[0033] When electrical connection is required, the plug board 50 is plugged into the socket 52. When electrical connection is required, the plug board 50 is unplugged from the socket 52. Then the power distribution module, power conversion module and output control module can be replaced.

[0034] The rear end of the shell 7 is provided with a plurality of jacks 53 along the front-to-back direction, and each of the jacks 53 is connected to a plug 54 for sliding forward and backward. A pressing portion 55 is radially fixed to the outer wall of the plug 54, and a secondary compression spring 56 is fixed to the front end of the plug 54 and the inner wall of the jack 53. A clamping plate 57 is fixed to the upper and lower ends of the socket 52. The clamping plate 57 is fixed to the shell 7 and can be bent and deformed up and down with the socket 52. A secondary extrusion protrusion 58 is fixed to the end face of the clamping plate 57 close to the inner wall of the jack 53. A main extrusion protrusion 59 is fixed to the inner wall. The main extrusion protrusion 59 and the auxiliary extrusion protrusion 58 correspond to each other vertically and can fit together. The contact surface between the main extrusion protrusion 59 and the auxiliary extrusion protrusion 58 is inclined. The insert 54 has a tendency to move backward under the elastic repulsive force of the auxiliary compression spring 56. As a result, the main extrusion protrusion 59 squeezes the auxiliary extrusion protrusion 58, causing the rear of the clamping plate 57 and the rear of the socket 52 to bend and contract vertically. When the insert 54 is pressed forward, the main extrusion protrusion 59 and the auxiliary extrusion protrusion 58 can be disengaged.

[0035] Furthermore, before inserting the plug board 50 into the socket 52, the pressing portion 55 is manually pressed forward to move the insert tube 54 forward, thereby releasing the contact between the main extrusion protrusion 59 and the secondary extrusion protrusion 58. At this time, when the plug board 50 is inserted into the socket 52, it can enter smoothly. After the insertion is completed, the pressure on the pressing portion 55 is released, and the elastic repulsive force of the secondary compression spring 56 causes the insert tube 54 and the main extrusion protrusion 59 to move backward, thereby squeezing the secondary extrusion protrusion 58, so that the rear part of the socket 52 is bent to squeeze the plug board 50, so that it can fit tightly with the plug board 50, thereby ensuring the stability of the electrical connection.

[0036] A rounded contact protrusion 60 is fixed to the upper and lower ends of the inner wall of the socket 52. The contact protrusion 60 is a dome-shaped long strip extending in the left and right directions, and the arc of the outer arc wall is a minor arc. A contact groove 61 is opened at the upper and lower ends of the plug board 50. When the plug board 50 is inserted into the socket 52, the contact protrusion 60 can match and fit into the contact groove 61. A guide seat 62 is fixed axially in the socket 53. The front part of the guide seat 62 is hollowed out from top to bottom for accommodating the splint 57 and the socket 52. The rear part of the guide seat 62 is penetrated from front to back for plugging in the plug board 50, and the rear part of the guide seat 62 is flared.

[0037] Furthermore, the flared structure at the rear of the guide seat 62 facilitates the entry and exit of the plug board 50, and the cooperation between the contact protrusion 60 and the contact groove 61 can improve the tightness of the fit on the one hand, and reduce the possibility of accidental separation on the other hand, thereby further improving the stability of the electrical connection.

[0038] The right rear part of the box body 1 is hinged with multiple positioning plates 63 made of transparent material, and the virtual hinge axis of each positioning plate 63 is vertically arranged. A fastening bolt 64 is inserted through the left part of each positioning plate 63, and multiple fastening seats 65 are fixed to the left end of the rear inner wall of the box body 1. The fastening bolt 64 can be threadedly connected with the fastening seat 65 front and back to fasten the positioning plate 63. The positioning plate 63 is penetrated by multiple positioning holes 66 front and back, and each positioning hole 66 corresponds to each insertion hole 53 front and back. The rear part of the support part 51 is screw-shaped, and the front is connected to a pressing cylinder 67 for sliding front and back. The rear end of the pressing cylinder 67 is fixed with a No. 3 compression spring 68. The rear part of the support part 51 is threaded with a screw ring 69. A toggle rod 70 is fixed to the right end of the screw ring 69. The front end of the screw ring 69 is flush with the front end of the toggle rod 70. The support part 51 is radially fixed with a holding part 71. The holding portion 71 is fixed to the insulation layer of the cable body 74, and the conductor of the cable body 74 passes through the holding portion 71 and is fixed to the plug plate 50. The toggle rod 70 and the rear portion of the support portion 51 can match the positioning hole 66 and be gap-insulated. When the screw ring 69 rotates to the rear end of the support portion 51 and the contact protrusion 60 is in contact with the contact groove 61, the No. 3 compression spring 68 does not deform. When the contact protrusion 60 is in contact with the contact groove 61 and the No. 3 compression spring 68 is not deformed, the front end of the pressing cylinder 67 is just in contact with the rear end of the plug tube 54. When the screw ring 69 moves forward, it can push the plug tube 54 forward by squeezing the No. 3 compression spring 68. When the contact protrusion 60 is in contact with the contact groove 61 and the No. 3 compression spring 68 is not deformed and the positioning plate 63 is tightened by the fastening bolt 64 and the fastening seat 65, the front end of the screw ring 69 is located on the rear side of the rear end of the positioning plate 63.

[0039] Furthermore, before fastening the power distribution module, power conversion module and output control module to the support frame 34, first release the threaded connection between the fastening bolts 64 and the fastening seat 65, then unfold the positioning plate 63 backwards, and then fasten the power distribution module, power conversion module and output control module to the support frame 34. Then, press the pressing part 55 to connect the plug board 50 with the socket 52, and then loosen the pressing part 55 and rotate the screw ring 69 so that the screw ring 69 is located at the rear end of the support part 51. At this time, the toggle rod 70 is horizontal to the right, and the No. 3 compression spring 68 is in an undeformed state. That is, the pressing cylinder 67 just contacts the rear end of the insert cylinder 54. At this time, the main extrusion protrusion 59 presses the auxiliary extrusion protrusion 58, and the contact protrusion 60 fits in contact with the contact groove 61. Then the positioning plate 63 is reset. Since the positioning hole 66 can be inserted with the toggle rod 70 and the support part 51 with a gap, the positioning hole 66 can pass through the toggle rod 70 and the holding part 71 smoothly, and the front end of the screw ring 69 is located on the rear side of the positioning plate 63. Then, the fastening bolt 64 is used to thread the fastening seat 65, and the installation and electrical connection of the distribution module, power conversion module and output control module are completed. When the power distribution module, power conversion module and output control module need to be disassembled or replaced, after the above process, the screw ring 69 can be moved forward along the support portion 51 by manually rotating the toggle lever 70 clockwise (rear view angle), thereby pushing the fastening bolt 64 and the pressing cylinder 67 forward, and then using the pressing cylinder 67 to push the insert cylinder 54, so that the insert cylinder 54 moves forward, thereby releasing the squeezing of the primary squeezing protrusion 59 on the secondary squeezing protrusion 58. As the toggle lever 70 continues to rotate, when it rotates nearly 270 degrees, under the joint repulsive force of the No. 3 compression spring 68 and the secondary compression spring 56, the pressing cylinder 67 is difficult to continue to move forward, so it will push the support portion 51 to move backward, that is, the plug board 50 is gradually pulled out of the socket 52, at this time, the screw of the fastening bolt 64 and the fastening seat 65 is released. 66 , and then the positioning plate 63 is unfolded backwards, so that the plug board 50 can be completely separated from the guide seat 62, and then the power distribution module, the power conversion module and the output control module can be replaced. After the replacement is completed, the cable plug is separated from the positioning hole 66 according to the position of the cable plug on the positioning plate 63 and re-plugged into the socket 52. In this way, the position of the cable plug relative to the positioning plate 63 can be limited, which is not easy to be confused during maintenance and is easy to distinguish, thereby improving maintenance efficiency. When the cable plug is separated from the positioning hole 66, it is only necessary to reverse the screw ring 69 so that the toggle rod 70 and the support part 51 can be removed through the positioning hole 66. During daily transportation or maintenance of the cable plug, the screw ring 69 is rotated to move the pressing cylinder 67 forward, so that the plug board 50 can be shielded and protected to a certain extent, thereby reducing the probability of damage.

[0040] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
