Description

Technical Field

[0001] The present invention relates to the technical field of charging stations, and in particular to a hidden new energy vehicle charging station. Background Art

[0002] With the continuous improvement of economic level and residents' income, the number of private cars is also increasing. The increase in the number of private cars is also causing increasing pollution to the environment. In the face of the problem of automobile exhaust emissions, the most effective way now is to develop new energy vehicles. New energy vehicles mainly refer to cars powered by clean energy. Nowadays, most new energy vehicles mainly use electricity as a driving energy source. New energy vehicles have many advantages over traditional fuel vehicles, such as environmental protection, energy saving, and low noise. The "gas station" of new energy vehicles is the charging station. The charging station can replenish electricity for new energy vehicles. It is generally composed of multiple parking spaces and multiple charging piles. The car is parked in the corresponding parking space and charged by the charging pile.

[0003] In the prior art, the charging piles of existing charging stations are often fixed on the wall or the ground. During long-term use, they are exposed to wind and sun, and their shells will be corroded, and even poor contact may occur.

[0015] Furthermore, a sealing rubber ring is glued to the lower surface of the sealing plate and the side wall of the lifting seat.

[0016] The present invention has the following advantages:

[0017] 1. When the charging pile is not in use, it is hidden in the pile slot and will not be exposed to the outside, thus avoiding the charging pile being exposed to the outside world and being exposed to wind and sun for a long time, resulting in corrosion and poor contact, which greatly improves the service life of the charging pile;

[0018] 2. When the car drives onto the load-bearing plate, the first and second pressure relief valves can be opened by the car's own gravity, thereby raising the charging pile. If a person only stands on the load-bearing plate, the charging pile will not rise, thus preventing criminals from damaging the charging pile and providing a certain degree of protection for the charging pile.

[0019] 3. The charging pile will rise only when the car is fully driven onto the load-bearing plate and the weight of the entire car is applied to the load-bearing plate. If the car is not fully positioned on the load-bearing plate, the charging pile will not rise. This ensures that the charging vehicle must be parked on the load-bearing plate in a standardized manner, thus avoiding the situation where one car occupies two charging pile positions and greatly improving the utilization rate of the charging pile.

[0020] 4. The charging station is an integrated production. You only need to dig a deep enough pit at the installation site and install the charging station in it. The adjustment of the charging station can be completed in the production workshop, which ensures that the installation is more convenient and the debugging of the charging station is more convenient;

[0021] 5. The charging pile will be charged only after it is raised, and when it is hidden in the pile slot, it is also in a power-off state, which prevents the charging pile from being powered on all the time, causing leakage and other situations, resulting in unnecessary losses;

[0022] 6. When the charging pile is rising and falling, the first gear will rotate, thereby driving the second gear to rotate, causing the cam column to rotate. The cam column drives the drive frame to reciprocate, thereby causing the pump block to reciprocate, pumping the water above the lifting seat into the transfer chamber and then discharging it, avoiding the accumulation of rainwater in the pile groove and affecting the charging pile.

DETAILED DESCRIPTION

[0033] Reference Figure 1-9A hidden new energy vehicle charging station includes a main body 1, the main body 1 is provided with a groove 2, a pile groove 6, and a driving groove 9, the main body 1 is slidably connected to a bearing plate 3 through the groove 2, a main sliding sleeve 4 is fixedly connected to the bottom wall of the groove 2, a main sliding block 5 is sealed and slidably connected in the main sliding sleeve 4, the main sliding block 5 is fixedly connected to the lower surface of the bearing plate 3, a lifting seat 7 is sealed and slidably connected in the pile groove 6, a charging pile 8 is arranged on the upper surface of the lifting seat 7, and the lifting seat 7 is a middle convex structure (such as Figure 2 As shown), the charging pile 8 is arranged on the protrusion, so that even if a certain amount of rainwater enters the pile groove 6, it will not contact the charging pile 8, which plays a certain protective role on the charging pile 8. The bottom wall of the driving groove 9 is fixedly connected with a secondary sliding sleeve 10, and the secondary sliding sleeve 10 is sealed and slidably connected with a secondary sliding block 11. The main sliding sleeve 4 and the main body 1 are jointly penetrated and fixedly connected with a first tube 12 and a second tube 13. The first tube 12, the main body 1, and the main sliding sleeve 4 are jointly penetrated and fixedly connected with a third tube 14. The second tube 13, the main body 1, and the main sliding sleeve 4 are jointly penetrated and fixedly connected with a fourth tube 15. An energizing mechanism is arranged in the pile groove 6, and a driving shaft 23 is rotatably connected between the two opposite inner side walls of the driving groove 9 through a bearing. The driving shaft 23 is penetrated and fixedly connected with a first gear 26. A blocking mechanism is arranged in the driving groove 9, and a drainage mechanism is arranged in the main body 1.

[0034] The entire charging station is an integrated setting, and all its components are included in the main body 1, that is, the entire charging station can be produced and debugged in the production workshop. During the on-site installation process, it is only necessary to dig a pit of corresponding depth and install the main body 1 in the pit, which makes on-site installation more convenient. The charging station can be debugged in the production workshop, and more and more complete debugging equipment can be used to fully debug it, making the debugging of the charging station more convenient.

[0035] The first tube 12 is fixedly connected to the bottom wall of the auxiliary sleeve 10 through the first tube 12, the main sleeve 4 is connected to the auxiliary sleeve 10, and the second tube 13 is connected to the main sleeve 4 and the pile groove 6. The main sleeve 4, the pile groove 6, the auxiliary sleeve 10, the first tube 12, the second tube 13, the third tube 14, and the fourth tube 15 are all filled with hydraulic oil. The first tube 12, the second tube 13, the third tube 14, and the fourth tube 15 are respectively provided with a first pressure relief valve 16, a second pressure relief valve 17, a third pressure relief valve 18, and a fourth pressure relief valve 19. The first tube 12, the second tube 13, the third tube 14, and the fourth tube 15 are respectively provided with a first pressure relief valve 16, a second pressure relief valve 17, a third pressure relief valve 18, and a fourth pressure relief valve 19. 3. Both the third pipe 14 and the fourth pipe 15 are provided with a one-way valve. The one-way valve in the first pipe 12 only allows the hydraulic oil to enter the auxiliary sleeve 10 from the main sleeve 4, and the one-way valve in the first pipe 12 is arranged between the main sleeve 4 and the third pipe 14. The one-way valve in the second pipe 13 only allows the hydraulic oil to enter the pile groove 6 from the main sleeve 4, and the one-way valve in the second pipe 13 is arranged between the main sleeve 4 and the fourth pipe 15. The one-way valve in the third pipe 14 only allows the hydraulic oil to enter the main sleeve 4 from the first pipe 12, and the one-way valve in the fourth pipe 15 The valve only allows hydraulic oil to enter the main sliding sleeve 4 from the second pipe 13. When the car enters the charging station, the car drives above the load plate 3. The gravity of the car itself causes the load plate 3 to slide down, thereby causing the main slider 5 to slide into the main sliding sleeve 4. First, the first pressure relief valve 16 is opened. At this time, the hydraulic oil enters the auxiliary sliding sleeve 10 through the first pipe 12, thereby causing the auxiliary slider 11 to slide up, and the sliding plate 27 is driven to slide up by the second spring 28, thereby causing the rack 29 to move upward, driving the first gear 26 meshing with it to rotate, thereby causing The driving shaft 23 rotates, causing the sealing plate 25 to rotate and open the pile groove 6. When the sealing plate 25 rotates to the limit position and cannot continue to rotate, the pressure increases to the second pressure relief valve 17 to open, allowing the hydraulic oil to enter the pile groove 6 through the second pipe 13. After the hydraulic oil enters the pile groove 6, the lifting seat 7 rises, thereby lifting the charging pile 8 to the main body 1. When the charging pile 8 is in use, it automatically rises out of the main body 1, and when not in use, it is hidden in the main body 1, thereby preventing the charging pile 8 from being exposed to the outside world for a long time and being exposed to wind and sun, resulting in a shortened lifespan.

[0036] It should be noted that the opening pressure of the first pressure relief valve 16 is less than the opening pressure of the second pressure relief valve 17, so that the hydraulic oil will first enter the auxiliary sleeve 10, so that the charging pile 8 will not rise until the sealing plate 25 is opened, and the opening pressure of the third pressure relief valve 18 is greater than the opening pressure of the fourth pressure relief valve 19, so that the sealing plate 25 will not rotate and close until the charging pile 8 drops into the pile groove 6, thereby ensuring the orderly operation of the charging station, and through the arrangement of the first pressure relief valve 16 and the second pressure relief valve 17, the first pressure relief valve 16 and the second pressure relief valve 17 can be opened only when the car drives onto the load-bearing plate 3 and the gravity of the car, and only when a person stands on the load-bearing plate 3 The charging pile 8 will not rise when the entire car is on the load-bearing plate 3, thereby preventing criminals from damaging the charging pile 8 and providing a certain degree of protection for the charging pile 8. At the same time, the charging pile 8 will rise only when the entire car is driven onto the load-bearing plate 3 so that the weight of the entire car is applied to the load-bearing plate 3. If the entire car is not entirely on the load-bearing plate 3, the gravity of the entire car is not entirely applied to the load-bearing plate 3, and the pressure is still not enough to open the first pressure relief valve 16 and the second pressure relief valve 17, and the charging pile 8 will not rise. As a result, the charging vehicle must be parked on the load-bearing plate 3 in a standardized manner, thereby avoiding the situation where one car occupies two charging piles 8, thereby greatly improving the utilization rate of the charging pile 8.

[0037] A plurality of guide sleeves 20 are fixedly connected to the inner bottom wall of the groove 2, a guide column 21 is slidably connected inside the guide sleeve 20, the guide column 21 is fixedly connected to the lower surface of the supporting plate 3, a first spring 22 is fixedly connected between the guide column 21 and the corresponding guide sleeve 20, and through the arrangement of the guide sleeve 20 and the guide column 21, the supporting plate 3 can stably move up and down in the vertical direction.

[0038] The power supply mechanism includes a power connection slot 30, which is provided on the inner top wall of the pile slot 6, an insulating plate 31 is slidably connected in the power connection slot 30, a plurality of third springs 32 are fixedly connected between the insulating plate 31 and the inner top wall of the power connection slot 30, a plurality of fixed electric blocks 34 are fixedly connected to the inner top wall of the power connection slot 30, the fixed electric blocks 34 are fixedly connected to the inner top wall of the power connection slot 30 by insulating glue, and the thickness of the insulating glue needs to reach a certain value to avoid the fixed electric blocks 34 from being connected to the main body 1, a plurality of movable electric blocks 33 are fixedly connected to the upper surface of the insulating plate 31, a top block 35 is fixedly connected to the upper surface of the lifting seat 7, and the setting position of the top block 35 corresponds to the insulating plate 31 (such as Figure 2 and Figure 7As shown, the movable electric block 33 is connected to the electrode of the charging pile 8 through a wire, and the fixed electric block 34 is connected to the power supply line through a wire, that is, the charging pile 8 can be powered on only after the fixed electric block 34 contacts the movable electric block 33, and the charging pile 8 is powered off after the fixed electric block 34 is separated from the movable electric block 33, so that the charging pile 8 is powered on only when the charging pile 8 is in use, and when hidden in the pile groove 6, the charging pile 8 is in a power-off state, thereby avoiding the charging pile 8 from remaining powered on for a long time when not in use, which may cause leakage and power loss.

[0039] The blocking mechanism includes a plurality of connecting plates 24, to which a sealing plate 25 is fixedly connected. The driving shaft 23 is fixedly connected to the connecting plate 24 through the connecting plate 24. A sliding plate 27 is slidably connected in the driving groove 9. A rack 29 is fixedly connected to the upper surface of the sliding plate 27. The rack 29 meshes with the first gear 26. A plurality of second springs 28 are fixedly connected between the sliding plate 27 and the auxiliary slider 11. The setting of the second spring 28 enables the auxiliary slider 11 to continue to slide down after the sealing plate 25 closes the pile groove 6, thereby stretching the second spring 28, so that the pressure of the sealing plate 25 on the main body 1 is increased, and the pile groove 6 is better blocked by the increase in pressure.

[0040] The drainage mechanism includes two transfer chambers 38, which are opened in the main body 1 and symmetrical about the driving groove 9. The main body 1 is rotatably connected with a driven shaft 36 through a bearing, and both ends of the driven shaft 36 extend into the two transfer chambers 38 respectively. One end of the driven shaft 36 located in the transfer chamber 38 is fixedly connected with a cam column 40, and a section of the driven shaft 36 located in the driving groove 9 is fixedly connected with a second gear 37, and the second gear 37 is meshed with the first gear 26. A piston 41 is sealed and slidably connected in the transfer chamber 38, and the side wall of the piston 41 close to the cam column 40 is fixed. The main body 1 is fixedly connected with a driving frame 39. During the rotation process, the cam column 40 will alternately contact the two inner side walls opposite to the driving frame 39, thereby driving the driving frame 39 to reciprocate. The cam column 40 abuts against the inner side wall of the driving frame 39. The main body 1 is fixedly connected with two fifth tubes 42 and sixth tubes 43. The fifth tube 42 connects the pile groove 6 with the corresponding transfer cavity 38. The lifting seat 7 is fixedly connected with two seventh tubes 44. The seventh tube 44 is connected with the corresponding fifth tube 42 through a hose 45. The setting of the hose 45 can ensure that the seventh tube 44 can be raised and lowered while the lifting seat 7 is raised and lowered. The pipe 44 is connected to the fifth pipe 42, and the sixth pipe 43 connects the corresponding transfer chamber 38 with the outside. On rainy days, after the sealing plate 25 is opened, the lifting seat 7 will rise to block the pile groove 6, and it is inevitable that some rainwater will enter the pile groove 6. Since the lifting seat 7 is a structure with a raised middle, the rainwater entering is accumulated above the lifting seat 7, but will not contact the charging pile 8. Since the upper surface of the lifting seat 7 is an inclined surface, the rainwater will accumulate in the direction of the seventh pipe 44 through the accumulation hole 46. During the up and down movement of the sliding plate 27, when the first gear 26 is driven to rotate by the rack 29, the first gear The wheel 26 will drive the second gear 37 meshing with it to rotate, thereby causing the driven shaft 36 to rotate, driving the cam column 40 to rotate, and the rotation of the cam column 40 will cause the drive frame 39 to reciprocate, driving the piston 41 to reciprocate. During the reciprocating movement of the piston 41, rainwater above the lifting seat 7 is pumped into the transfer chamber 38 through the fifth tube 42, the hose 45, and the seventh tube 44, and then discharged through the sixth tube 43. Therefore, during each opening and closing process of the sealing plate 25, the rainwater accumulated on the upper surface of the lifting seat 7 is discharged to prevent excessive accumulation of rainwater from contacting the charging pile 8.

[0041] Both the fifth tube 42 and the sixth tube 43 are provided with a one-way valve. The one-way valve in the fifth tube 42 only allows rainwater and air to enter the fifth tube 42 from the hose 45, and the one-way valve in the sixth tube 43 only allows air and rainwater to be discharged from the transfer chamber 38 to the outside.

[0042] It should be noted that the surfaces of the first gear 26, the driving shaft 23, the driven shaft 36, the second gear 37, the rack 29, and the sliding plate 27 are all coated with an anti-rust coating to ensure their good anti-rust ability and avoid rusting during exposure to the outside world during work.

[0043] The upper surface of the lifting seat 7 is an inclined surface (such as Figure 2 As shown in the figure, the height gradually decreases from the groove 2 toward the seventh tube 44, and the lifting seat 7 is provided with a storage hole 46. The inclined surface allows rainwater falling on the lifting seat 7 to be accumulated in the direction of the seventh tube 44, and the opening of the storage hole 46 facilitates the flow of rainwater, ensuring that rainwater is accumulated above the seventh tube 44 and can be better absorbed and discharged.

[0044] The number of teeth of the first gear 26 is greater than that of the second gear 37. The number of teeth of the first gear 26 is five times that of the second gear 37, so that the second gear 37 is accelerated under the drive of the first gear 26, thereby increasing the rotation speed of the cam column 40, and finally increasing the reciprocating motion frequency of the drive frame 39, thereby improving the drainage efficiency.

[0045] The lower surface of the sealing plate 25 and the side wall of the lifting seat 7 are both glued with a sealing rubber ring. Figure 8 As shown, it can be in contact with the upper surface of the main body 1, and when the sealing plate 25 closes the pile groove 6, it plays a sealing role to prevent external dust and rainwater from entering the pile groove 6. The sealing rubber ring on the side wall of the lifting seat 7 can seal the pile groove 6 after the lifting seat 7 is raised, so as to prevent external dust and rainwater from entering the pile groove 6 during the use of the charging pile 8.

[0046] In the present invention, during the installation process, a rectangular pit of corresponding depth is dug at the installation position, and the main body 1 is hoisted into the pit by hoisting equipment, and the power supply line is connected to the fixed power block 34 in the main body 1, and then the pit is filled so that the upper surface of the main body 1 is flush with the ground.

[0047] When the car enters the charging station, the car drives above the load-bearing plate 3. The car's own gravity causes the load-bearing plate 3 to slide down, thereby causing the main slider 5 to slide into the main sleeve 4, first opening the first pressure relief valve 16. At this time, the hydraulic oil enters the auxiliary sleeve 10 through the first pipe 12, thereby causing the auxiliary slider 11 to slide up, and the sliding plate 27 is driven to slide up by the second spring 28, thereby causing the rack 29 to move upward, driving the first gear 26 meshing with it to rotate, thereby causing the driving shaft 23 to rotate, causing the sealing plate 25 to rotate, and opening the pile groove 6.

[0048] When the sealing plate 25 rotates to the limit position and cannot continue to rotate, the pressure increases until the second pressure relief valve 17 opens, allowing the hydraulic oil to enter the pile groove 6 through the second pipe 13. After the hydraulic oil enters the pile groove 6, the lifting seat 7 rises, thereby lifting the charging pile 8 to the main body 1. At the same time, after the charging pile 8 is lifted to the main body 1, the lifting seat 7 contacts the inner wall of the pile groove 6 and seals the pile groove 6 through the sealing rubber ring on the side wall of the lifting seat 7.

[0049] When the charging pile 8 is lifted out of the main body 1, the lifting seat 7 will also drive the top block 35 to rise together. The top block 35 contacts the insulating plate 31 and pushes the insulating plate 31 to move upward until the fixed electric block 34 contacts the corresponding movable electric block 33. At this time, the charging pile 8 is also completely lifted out of the main body 1. At the same time, the charging pile 8 is powered on, the charging gun on the charging pile 8 is removed, and the car can be charged.

[0050] After charging is completed, the car drives away from the carrying plate 3. Under the elastic force of the first spring 22, the carrying plate 3 rises and resets. At this time, the fourth pressure relief valve 19 opens first, so that the hydraulic oil in the pile groove 6 returns to the main sliding sleeve 4 first, so that the lifting seat 7 first drives the charging pile 8 to descend into the pile groove 6. After the lifting seat 7 descends to the limit position, the third pressure relief valve 18 will be opened, so that the sliding plate 27 slides down, and the rack 29 is meshed with the first gear 26, so that the sealing plate 25 rotates and closes the pile groove 6.

[0051] On rainy days, after the sealing plate 25 is opened, the lifting seat 7 will rise to block the pile groove 6, and it is inevitable that some rainwater will enter the pile groove 6. Since the lifting seat 7 is a structure with a protrusion in the middle, the rainwater that enters is accumulated above the lifting seat 7, but will not contact the charging pile 8. Since the upper surface of the lifting seat 7 is an inclined surface, the rainwater will accumulate in the direction of the seventh tube 44 through the accumulation hole 46. During the up and down movement of the sliding plate 27, when the first gear 26 is driven to rotate by the rack 29, the first gear 26 will drive the second gear meshing with it. 37 rotates, thereby causing the driven shaft 36 to rotate, driving the cam column 40 to rotate, and the rotation of the cam column 40 causes the driving frame 39 to reciprocate, driving the piston 41 to reciprocate. During the reciprocating movement of the piston 41, rainwater above the lifting seat 7 is pumped into the transfer chamber 38 through the fifth tube 42, the hose 45, and the seventh tube 44, and then discharged through the sixth tube 43. Therefore, during each opening and closing process of the sealing plate 25, the rainwater accumulated on the upper surface of the lifting seat 7 is discharged to prevent excessive accumulation of rainwater from contacting the charging pile 8.
