Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a new energy charging pile with a hub function. Background Technology

[0002] The charging pile itself refers to the charging equipment that provides charging services for electric vehicles. There are two types: floor-mounted charging piles and wall-mounted charging piles. They adopt a time-based, energy-based, and cost-based charging method and are charged through a power socket or power cord plug.

[0003] According to research, the power cords of existing charging stations are usually exposed on the outside of the station body for ease of use. Some stations have a hanging bracket on the outside of the station body for winding the cord. When in use, the cord is stretched through the plug at the end to charge the car. However, the cord is prone to tangling and twisting when wound on the hanging bracket. Moreover, the exposed cord poses many safety hazards. There is a lot of foot traffic near the charging station, which may cause damage by touching or running over the cord.

[0004] Therefore, a new type of charging station that can aggregate cables is proposed to address the safety hazards or tangling issues that can easily occur with exposed wiring harnesses. Summary of the Invention

[0005] To address the safety hazards or tangling issues arising from the exposed wiring at the end of the charging gun in existing technologies, the present invention adopts the following technical solution:

[0006] A new energy charging pile with a hub function includes a supporting square tube. A main body shell with an opening facing forward is fixed to the top of the supporting square tube. An inner fixing plate is fixed to the rear inner wall of the main body shell, and an emergency stop switch and a power supply module are arranged on the front of the inner fixing plate. A power supply cable harness is arranged at the output end of the power supply module, and a charging gun head is fixed to the end of the power supply cable harness away from the power supply module. A panel is fixed to the front opening of the main body shell, and a display adapted to the power supply module is arranged on the panel. A rectangular hole is opened at the top of the main body shell near the supporting square tube, and the surface of the inner fixing plate is located on the supporting square tube. A spring fixing block is fixed at the top, a tension spring is fixed on the lower surface of the spring fixing block, and a roller frame is fixed at the bottom of the tension spring. Two vertical grooved slide rails with opposite openings are fixed on the vertical inner wall of the supporting square tube. The same counterweight block is slidably connected between the two grooved slide rails. A roller hanger is fixed at the top of the counterweight block, and grooved pulleys are rotatably connected in both roller frame one and roller hanger two. A wire hole is opened on the front of the supporting square tube near the top. After the power transmission module is led out, the power transmission cable passes through the grooved pulley in roller hanger two, then through the grooved pulley in roller frame one, and finally passes through the wire hole.

[0007] Preferably, the panel has a toggle hole near the top that matches the emergency stop switch; the front of the main body shell has a forward-extending sunshade near the top; the sunshade can provide some protection for the emergency stop switch, and the location of the emergency stop switch is obviously easy to operate, thus improving the safety performance of the device.

[0008] Preferably, the panel has a socket near the top, the shape of which is adapted to the shape of the charging gun head; a gun head retainer is fixed on the rear side of the panel near the socket, and an electronic lock is provided above the gun head retainer to prevent the charging gun head from being accidentally knocked off.

[0009] Preferably, a conductor is provided on the front side of the supporting square tube near the wire hole, and the conductor includes two P-shaped shafts fixed to the surface of the supporting square tube below the wire hole, and the same fixed support roller is rotatably connected between the two P-shaped shafts; a guide rail fixing seat is fixed on the surface of the supporting square tube above the wire hole, and a sliding roller frame that can slide vertically up and down is slidably connected in the guide rail fixing seat, and a fixed support roller two identical to the fixed support roller one is provided at the bottom end of the sliding roller frame, and an annular groove with a diameter adapted to the outer diameter of the power transmission cable harness is reserved on the outer circumference of the fixed support roller one.

[0010] Preferably, the top of the guide rail fixing seat is provided with a shaft mounting seat, and a horizontally rotating transmission shaft is provided on the shaft mounting seat. A worm gear and a variable diameter abutment are fixed at the front and rear ends of the transmission shaft, respectively. A protruding post is fixed at the top of the sliding roller frame below the variable diameter abutment. Two symmetrical side guard plates are fixed on both sides of the top of the guide rail fixing seat, and the same worm gear is rotatably connected between the two side guard plates near the top. The worm gear and the worm wheel mesh with each other. An adjusting handwheel is fixed at one end of the worm gear.

[0011] Preferably, the top and front of the two side guard plates are fixed with the same L-shaped clamping plate, and the bottom of the L-shaped clamping plate has a U-shaped notch in the middle; the diameter of the U-shaped notch is larger than the diameter of the power transmission cable harness; this can constrain the power transmission cable harness in the left and right directions to prevent excessive swing and slippage between the fixed idler roller one and the fixed idler roller two.

[0012] Preferably, a U-shaped cleaning brush with an upward opening is fixed on the front side of the L-shaped card plate near the U-shaped notch; this can effectively clean the dust from the surface of the incoming and outgoing power transmission cable harness.

[0013] Preferably, spherical grooves are formed on both sides of the counterweight near the bottom of the grooves of the two grooved slide rails, and ball bearings are embedded in the spherical grooves; this can reduce the resistance when the counterweight slides, thereby reducing the tension on the power transmission cable harness.

[0014] Preferably, one of the grooved slide rails has a strip-shaped hole near the top of the groove bottom, and a backstop rack with its toothed surface facing the counterweight is engaged in the strip-shaped hole; a positioning mechanism is fixed on the upper surface of the counterweight near the backstop rack.

[0015] Preferably, the positioning mechanism includes a T-shaped shaft frame fixed on the counterweight, a swing hook rod rotatably connected to the middle of the T-shaped shaft frame near the anti-reverse rack, and a permanent magnet fixed to the bottom end of the swing hook rod. An electromagnet that attracts the permanent magnet when energized is fixed to the bottom end of the T-shaped shaft frame. A compression spring is fixed between the top end of the swing hook rod and the T-shaped shaft frame. When the power transmission cable is continuously pulled, the counterweight carries the positioning mechanism to rise continuously until the swing hook rod and the anti-reverse rack suddenly engage. At this time, the power transmission cable loses the pulling force of the counterweight. When the charging is finished and needs to be reset, it is only necessary to energize the electromagnet. At this time, the swing hook rod disengages from the anti-reverse rack.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. By setting up a roller hanger with a counterweight, when the charging gun head is not in use, the excess power cable harness can be pulled into the supporting square tube by the counterweight and the grooved pulley in the roller hanger, thus providing good protection for the power cable harness. When the internal power cable harness needs to be used, it can be slowly pulled outward to overcome the weight of the counterweight.

[0018] 2. By setting two opposing fixed rollers, namely fixed roller one and fixed roller two, the power transmission cable harness can have a predetermined trajectory when entering and exiting the cable hole, thereby avoiding friction with the opening of the cable hole and thus preventing wear on the cable sheath.

[0019] 3. By setting up variable diameter abutment rollers and worm gears, the sliding roller frame can be controlled to continuously press downwards, thereby pressing the power transmission harness tightly. This not only prevents the power transmission harness from deviating, but also locks the power transmission harness by continuing to press downwards.

[0020] 4. Through the positioning mechanism and the matching anti-reverse rack, when the power transmission harness is pulled to its maximum length, the counterweight will be locked by the positioning mechanism and the anti-reverse rack. At this time, the power transmission harness loses the pulling force of the counterweight, thereby preventing the power transmission harness from softening due to heat during charging and being torn by pulling.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In this embodiment, refer to Figure 1-8A new energy charging pile with a hub function includes a supporting square tube 1 vertically fixed to the ground. A main body shell 4 with an opening facing forward and an overall rectangular box structure is fixed to the top of the supporting square tube 1. An inner fixing plate 10 is fixed to the inner wall of the rear side of the main body shell 4. An emergency stop switch 6 and a power supply module 17 are provided on the front of the inner fixing plate 10. A power supply cable harness 7 is provided at the output end of the power supply module 17. A charging gun head 5 is fixed to the end of the power supply cable harness 7 away from the power supply module 17. A panel 3 is fixed at the front opening of the main body shell 4, and a display 8 adapted to the power supply module 17 is provided on the panel 3. A rectangular hole is opened at the top of the main body shell 4 near the supporting square tube 1. A spring fixing block 12 is fixed to the surface of the inner fixing plate 10 at the top of the supporting square tube 1. A tension spring is fixed to the lower surface of the spring fixing block 12, and a roller frame 16 is fixed to the bottom end of the tension spring. The vertical inner wall of the supporting square tube 1 is fixed... There are two vertical, oppositely opening grooved slide rails 15, and the same counterweight 13 is slidably connected between the two grooved slide rails 15. A roller hanger 2 19 is fixed to the top of the counterweight 13, and grooved pulleys are rotatably connected in both the roller frame 1 16 and the roller hanger 2 19. A wire hole 101 is opened on the front of the supporting square tube 1 near the top. The power transmission cable 7 is led out from the power supply module 17 and passes through the grooved pulley in the roller hanger 2 19, then through the grooved pulley in the roller frame 1 16, and finally through the wire hole 101. By setting the roller hanger 2 19 with the counterweight 13, when the charging gun head 5 is not in use, the excess power transmission cable 7 will be pulled into the supporting square tube 1 by the counterweight 13 and the grooved pulley in the roller hanger 2 19, thus providing good protection for the power transmission cable 7. When the internal power transmission cable 7 needs to be used, it can be slowly pulled outward to overcome the gravity of the counterweight 13.

[0032] Reference Figure 1 The panel 3 has a toggle hole near the top that matches the emergency stop switch 6; the front of the main body shell 4 has a forward-extending sunshade near the top; the sunshade can provide some protection for the emergency stop switch 6, and the location of the emergency stop switch 6 is obviously easy to operate, which improves the safety performance of the device.

[0033] Reference Figures 2-3 The panel 3 has a socket near the top, and the shape of the socket matches the shape of the charging gun head 5. The back of the panel 3 is fixed with a gun head sleeve 11 near the socket. An electronic lock is provided on the top of the gun head sleeve 11 to prevent the charging gun head 5 from being accidentally knocked off.

[0034] Reference Figures 4-5A conductor 2 is provided on the front side of the supporting square tube 1 near the wire hole 101. The conductor 2 includes two P-shaped shafts 205 fixed to the surface of the supporting square tube 1 below the wire hole 101. The same fixed roller 206 is rotatably connected between the two P-shaped shafts 205. A guide rail fixing seat 201 is fixed on the surface of the supporting square tube 1 above the wire hole 101. A sliding roller frame 207 that can slide vertically up and down is slidably connected in the guide rail fixing seat 201. A fixed roller 206 with the same fixed roller 206 as the fixed roller 206 is provided at the bottom end of the sliding roller frame 207. The outer circumference of the fixed roller 206 has a pre-reserved annular groove with a diameter that matches the outer diameter of the power transmission cable 7. By setting two opposing fixed rollers 206 and fixed roller 2, the power transmission cable 7 can have a predetermined trajectory when entering and exiting the wire hole 101, thereby avoiding friction with the opening of the wire hole 101 and thus preventing wear on the cable sheath.

[0035] Reference Figures 4-5 The top of the guide rail fixing seat 201 is reserved with a shaft mounting seat, and a horizontally rotating transmission shaft 210 is provided on the shaft mounting seat. The front and rear ends of the transmission shaft 210 are respectively fixed with a worm gear 213 and a variable diameter abutment wheel 209. The top of the sliding roller frame 207 is fixed with a protruding post 208 below the variable diameter abutment wheel 209. Two symmetrical side guard plates 204 are fixed on both sides of the top of the guide rail fixing seat 201. The two side guard plates 204 are rotatably connected to the same worm gear 211 near the top. The worm gear 211 meshes with the worm gear 213. One end of the worm gear 211 is fixed with an adjusting handwheel 212. Through the variable diameter abutment wheel 209 and the worm gear 213, the sliding roller frame 207 can be controlled to continuously press downward, thereby pressing the power transmission harness 7 tightly. This not only prevents the power transmission harness 7 from deviating, but also locks the power transmission harness 7 by continuing to press downward.

[0036] Reference Figure 5 The top and front of the two side guard plates 204 are fixed with the same L-shaped clamping plate 202, and the bottom of the L-shaped clamping plate 202 has a U-shaped notch 203; the diameter of the U-shaped notch 203 is larger than the diameter of the power transmission cable 7; it can constrain the power transmission cable 7 in the left and right directions to prevent the swing amplitude from being too large and causing it to slip off between the fixed idler roller 1 206 and the fixed idler roller 2.

[0037] Reference Figure 5 The front of the L-shaped card plate 202 is fixed with an upward-facing U-shaped cleaning brush 9 near the U-shaped notch 203; it can effectively clean the dust from the surface of the incoming and outgoing power transmission cable harness 7.

[0038] In this invention, spherical grooves are opened on both sides of the counterweight 13 near the bottom of the grooves of the two grooved slide rails 15, and ball bearings are embedded in the spherical grooves; this can reduce the resistance when the counterweight 13 slides, thereby reducing the tension on the power transmission cable harness 7.

[0039] Reference Figures 7-8 One of the grooved slide rails 15 has a slotted hole near the top of the slot, and a toothed rack 18 with its toothed surface facing the counterweight 13 is engaged in the slotted hole; a positioning mechanism 14 is fixed on the upper surface of the counterweight 13 near the side of the toothed rack 18; through the positioning mechanism 14 and the matching toothed rack 18, when the power transmission cable 7 is pulled to its longest length, the counterweight 13 will be locked by the positioning mechanism 14 and the toothed rack 18. At this time, the power transmission cable 7 loses the pulling force of the counterweight 13, thereby preventing the power transmission cable 7 from softening due to heat during charging and being torn due to being pulled.

[0040] Reference Figures 7-8 The positioning mechanism 14 includes a T-shaped shaft frame 141 fixed on the counterweight 13. A swing hook rod 144 is rotatably connected to the middle of the T-shaped shaft frame 141 near the anti-reverse rack 18. A permanent magnet 143 is fixed to the bottom end of the swing hook rod 144. An electromagnet 142 is fixed to the bottom end of the T-shaped shaft frame 141, which attracts the permanent magnet 143 when energized. A compression spring 145 is fixed between the top end of the swing hook rod 144 and the T-shaped shaft frame 141. When the power transmission cable harness 7 is continuously pulled, the counterweight 13 carries the positioning mechanism 14 to rise continuously until the swing hook rod 144 suddenly engages with the anti-reverse rack 18. At this time, the power transmission cable harness 7 loses the pulling force of the counterweight 13. When the charging is finished and needs to be reset, it is only necessary to energize the electromagnet 142. At this time, the swing hook rod 144 disengages from the anti-reverse rack 18.

[0041] Working principle: Before using this device, the electronic lock used to lock the charging gun head 5 is unlocked by operating on the display screen 8. Then the charging gun head 5 can be removed for charging. If the power supply cable 7 is not long enough, simply pull the power supply cable 7 outward slowly until you hear a "click" sound from the swing hook rod 144 in the positioning mechanism 14. This indicates that the swing hook rod 144 has engaged with the anti-reverse rack 18. At this time, the power supply cable 7 loses the pulling force of the counterweight 13. When it is time to reset after charging, simply energize the electromagnet 142. At this time, the swing hook rod 144 will disengage from the anti-reverse rack 18. When the charging gun head 5 is not in use, the excess power supply cable 7 will be pulled into the support square tube 1 by the counterweight 13 and the grooved pulley in the roller hanger 19. When the internal power supply cable 7 needs to be used, simply pull it outward slowly to overcome the gravity of the counterweight 13.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
