Description

Technical Field

[0001] This utility model relates to the field of lifting charging pile technology, specifically, to a lifting charging pile. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: regular charging and fast charging. Users can use a specific charging card to swipe on the human-machine interface provided by the charging pile to perform operations such as selecting the charging method, charging time, and printing cost data. The charging pile display screen can display data such as charging amount, cost, and charging time.

[0003] According to a public announcement (Announcement No.: CN 220639562U), a height-adjustable charging pile includes a charging box body. The outside of the charging box body is equipped with a power supply device and a charging indicator device. The inside of the charging box body is equipped with a heat dissipation device and a control device. The power supply device and heat dissipation device are electrically connected to the control device. Support legs are installed at the bottom of the charging box body, and the support legs are equipped with a height adjustment device for the charging box body. The control device is a wireless charging transmitter controller that can receive control signals to change its power supply. This product utilizes the height adjustment device on the support legs to adjust the height of the charging box body, eliminating the height difference between the charging part of the device and the power supply part of the charging pile. It eliminates the need to elevate the device or charging pile, making it more convenient than existing technologies.

[0004] However, the internal components such as the heat dissipation device, control device, and support legs in the above-mentioned applications are difficult to cooperate with to achieve the function of automatic lifting and lowering of the charging pile, and cannot better protect the charging pile. Therefore, we propose a lifting and lowering charging pile. Utility Model Content

[0005] This utility model proposes a lifting charging pile, which solves the problems mentioned in the above documents.

[0006] The technical solution of this utility model is as follows: it includes a charging pile, a charging port is provided on the side of the charging pile, and a lifting and protective device is provided at the bottom of the charging pile.

[0007] Furthermore, the lifting and protective device includes a support plate, an extension rod fixedly connected to the bottom of the support plate, a threaded sleeve fixedly connected to the side of the extension rod, a threaded rod threadedly connected to the circumferential surface of the threaded sleeve, a three-phase asynchronous motor fixedly connected to the bottom of the threaded rod, a fixing plate fixedly connected to the bottom of the three-phase asynchronous motor, and a limit rod fixedly connected to the top of the fixing plate. This design enables the extension rod to be driven by the threaded sleeve to lift and lower the charging pile, improving work efficiency and achieving automation.

[0008] Furthermore, the limiting rod is slidably connected to the threaded sleeve, and a lifting box is fixedly connected to the side of the fixing plate. This design allows the threaded sleeve to reciprocate vertically through the limiting action of the limiting rod.

[0009] Furthermore, the height of the limiting rod is lower than that of the threaded rod, and there is a gap between the threaded rod and the charging pile. This design is to prevent the limiting rod from being too high and obstructing the operation of the gear at the top of the threaded rod.

[0010] Furthermore, the tray is made of a rigid metal material, there is a gap between the top of the charging pile and the lifting box, and the extension rod is also made of a rigid metal material. This design ensures that the tray can support the weight of the charging pile.

[0011] Furthermore, an automatic sliding cover opening device is provided at the top of the threaded rod. This device includes a gear, the bottom of which is fixedly connected to the top of the threaded rod. An extension plate is fixedly connected to the top of the fixed plate, and a rotating shaft is rotatably connected to the side of the extension plate. A second gear is rotatably connected to the side of the rotating shaft. A sliding cover is slidably connected to the top of the lifting box, and a rack is fixedly connected to the bottom of the sliding cover. This design is to prevent rainwater from damaging the charging pile during rainy days, thus improving safety.

[0012] Furthermore, the gear meshes with a second gear, which in turn meshes with a rack. This design is intended to drive the operation of the automatic sliding cover opening device via gears.

[0013] Furthermore, a sliding groove is provided at the bottom of the lifting box, and a sliding block is slidably connected to the bottom of the sliding cover. This design is to enable the sliding cover to open and close, and to ensure that the sliding cover will not fall off after being opened.

[0014] Furthermore, the sliding groove has two sections, the sliding block has two sections, and the height of the threaded rod is lower than the height of the lifting box. This design is to allow for more complete and unobstructed sliding between the sliding cover and the lifting box.

[0015] Furthermore, the extension plate is higher than the threaded rod, and the diameter of the rotating shaft is smaller than the diameter of the second gear. This design allows for better meshing of the second gear with the other gears without affecting the operation of other devices.

[0016] Furthermore, the side of the sliding groove is located on the displacement trajectory of the sliding block, and the sliding cover is made of a waterproof sealing material. This waterproof sealing design of the sliding cover is to prevent damage to the charging pile during the rainy season.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] 1. In this utility model, the output shaft of the three-phase asynchronous motor rotates, driving the threaded rod to rotate. The rotation of the threaded rod drives the threaded sleeve to reciprocate vertically under the restriction of the limit rod. The reciprocating vertical movement of the threaded sleeve drives the extension rod to reciprocate vertically. The reciprocating vertical movement of the extension rod drives the pallet to reciprocate vertically. The reciprocating vertical movement of the pallet drives the charging pile to reciprocate vertically, thus realizing the automatic lifting function of the charging pile.

[0019] 2. In this utility model, the three-phase asynchronous motor, threaded rod, gear, second gear and other components cooperate to realize that the output shaft of the three-phase asynchronous motor rotates to drive the threaded rod to rotate, the threaded rod rotates to drive the gear to rotate, the gear rotates to drive the second gear meshing with it to rotate, the second gear rotates to drive the rack meshing with it to perform reciprocating horizontal motion, the rack reciprocating horizontal motion drives the sliding cover to achieve the function of opening and closing under the action of the sliding block, thereby realizing the functions of automatic lifting and protection.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1

[0029] like Figures 1-5 As shown in the figure, this embodiment proposes a lifting charging pile including a charging pile 1, a charging port 2 on the side of the charging pile 1, and a lifting protection device 3 at the bottom of the charging pile 1.

[0030] The lifting and protective device 3 includes a support plate 31. An extension rod 32 is fixedly connected to the bottom of the support plate 31. A threaded sleeve 33 is fixedly connected to the side of the extension rod 32. A threaded rod 34 is threadedly connected to the circumference of the threaded sleeve 33. A three-phase asynchronous motor 35 is fixedly connected to the bottom of the threaded rod 34. A fixing plate 36 is fixedly connected to the bottom of the three-phase asynchronous motor 35. A limit rod 37 is fixedly connected to the top of the fixing plate 36. This design allows the extension rod 32 driven by the threaded sleeve 33 to lift and lower the charging pile 1, improving work efficiency and achieving automation.

[0031] The limiting rod 37 is slidably connected to the threaded sleeve 33, and the lifting box 38 is fixedly connected to the side of the fixing plate 36. This design allows the threaded sleeve 33 to reciprocate vertically through the limiting action of the limiting rod 37.

[0032] The height of the limiting rod 37 is lower than that of the threaded rod 34, and there is a gap between the threaded rod 34 and the charging pile 1. This design is to prevent the limiting rod 37 from being too high and obstructing the operation of the gear 41 at the top of the threaded rod 34.

[0033] The tray 31 is made of rigid metal, and there is a gap between the top of the charging pile 1 and the lifting box 38. The extension rod 32 is also made of rigid metal. This design ensures that the tray 31 can support the weight of the charging pile 1.

[0034] In this embodiment, the three-phase asynchronous motor 35 is started. The output shaft of the three-phase asynchronous motor 35 rotates, driving the threaded rod 34 to rotate. The rotation of the threaded rod 34 drives the threaded sleeve 33 to reciprocate vertically under the restriction of the limiting rod 37. The reciprocating vertical movement of the threaded sleeve 33 drives the extension rod 32 to reciprocate vertically. The reciprocating vertical movement of the extension rod 32 drives the pallet 31 to reciprocate vertically. The reciprocating vertical movement of the pallet 31 drives the charging pile 1 to reciprocate vertically, thereby realizing the automatic lifting function of the charging pile 1, improving work efficiency and enhancing automation.

[0035] Example 2

[0036] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, a second embodiment is proposed, including an automatic sliding cover opening device 4 at the top of the threaded rod 34. The automatic sliding cover opening device 4 includes a gear 41, the bottom of which is fixedly connected to the top of the threaded rod 34. An extension plate 42 is fixedly connected to the top of the fixing plate 36, and a rotating shaft 43 is rotatably connected to the side of the extension plate 42. A second gear 44 is rotatably connected to the side of the rotating shaft 43. A sliding cover 45 is slidably connected to the top of the lifting box 38, and a rack 46 is fixedly connected to the bottom of the sliding cover 45. This design is to prevent rainwater from damaging the charging pile 1 on rainy days, thus improving safety.

[0037] Gear 41 meshes with second gear 44, and second gear 44 meshes with rack 46. This design is intended to drive the operation of automatic sliding cover opening device 4 via gear 41.

[0038] The bottom of the lifting box 38 is provided with a sliding groove 47, and the bottom of the sliding cover 45 is slidably connected with a sliding block 48. This design is to enable the sliding cover 45 to open and close, and to ensure that the sliding cover 45 will not fall off after being opened.

[0039] Two sliding grooves 47 and two sliding blocks 48 are provided. The height of the threaded rod 34 is lower than the height of the lifting box 38. This design is to allow the sliding cover 45 to slide more fully with the lifting box 38 without obstruction.

[0040] The extension plate 42 is higher than the threaded rod 34, and the diameter of the rotating shaft 43 is smaller than the diameter of the second gear 44. This design is intended to allow the second gear 44 to mesh better with the gear 41 without affecting the operation of other devices.

[0041] The side of the sliding groove 47 is located on the displacement trajectory of the sliding block 48, and the sliding cover 45 is made of waterproof sealing material. This waterproof sealing design of the sliding cover 45 is to prevent damage to the charging pile 1 during the rainy season.

[0042] In this embodiment, the three-phase asynchronous motor 35 is started. The output shaft of the three-phase asynchronous motor 35 rotates, which drives the threaded rod 34 to rotate. The rotation of the threaded rod 34 drives the gear 41 to rotate. The rotation of the gear 41 drives the second gear 44 meshing with it to rotate. The rotation of the second gear 44 drives the rack 46 meshing with it to reciprocate horizontally. The reciprocating horizontal movement of the rack 46 drives the sliding cover 45 to open and close under the action of the sliding block 48, thereby realizing the functions of automatic lifting and protection.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
