Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a sliding rail wall-mounted car charging pile. Background Technology

[0002] A charging station is a device that provides electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. With the rapid development of the new energy vehicle industry, the demand for charging stations is increasing daily. The charging station industry has undergone a rapid construction and development process.

[0003] Patent document CN112977136B discloses a sliding rail movable wall-mounted car charging pile, including a charging pile and a sliding rail. A moving device is slidably engaged at the top of the sliding rail. The moving device includes a moving plate sleeved on the top of the sliding rail, and the moving plate slides radially back and forth along the sliding rail. A locking component that is movably connected to the sliding rail is fixedly installed on one side of the moving plate. The top of the moving plate is connected to the bottom of the charging pile through a rotating device. The rotating device includes a chassis fixedly connected to the top of the moving plate and a top plate fixedly connected to the bottom of the charging pile.

[0004] Existing technologies for charging electric vehicles typically utilize the lateral sliding of the charging pile on a rail to bring it closer to the charging port of the electric vehicle. However, in practice, the charging port of an electric vehicle is usually located at the rear of the car. When a user drives forward into a charging space, the lateral movement of the charging pile can only bring it closer to one side of the charging port, but there is still a considerable distance between them. This results in low adaptability of a single-length charging cable, reducing the convenience of charging. Furthermore, it is difficult to effectively limit the cable during the movement of the charging pile, which can easily cause the cable to scatter and become tangled, thus affecting the normal movement of the charging pile. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sliding rail wall-mounted car charging station.

[0009] Preferably, the longitudinal moving mechanism includes four limiting frames, which are respectively fixedly connected to the upper and lower ends of the mounting plate and the protective box. Each limiting frame has two connecting blocks slidably connected inside. Multiple sets of rotating rods are arranged between corresponding two limiting frames, with two rotating rods in each set. The centers of the two rotating rods in the same set are rotatably connected to a limiting shaft. One end of each of two adjacent sets of rotating rods is rotatably connected. Each connecting block is rotatably connected to one end of the corresponding rotating rod. Two hydraulic cylinders are fixedly mounted on the mounting plate. The piston shafts of the hydraulic cylinders pass through the mounting plate and extend into the corresponding limiting frame, where they are fixedly connected to a U-shaped bracket. The U-shaped bracket is fixedly connected to the limiting shaft near the mounting plate. The charging pile body includes a pile body, a charging cable, and a charging gun. The charging cable is electrically connected between the pile body and the charging gun, and one end of the power supply cable is electrically connected to the pile body.

[0010] Preferably, two connecting brackets are fixedly connected to one side of the mounting plate, and telescopic rods are rotatably connected inside each connecting bracket. Limit pins are fixedly connected to both sides of the protective box, and one end of each telescopic rod is rotatably inserted into the corresponding limit pin.

[0011] Preferably, a limiting collar is fixedly connected to one side of the mounting plate, and a circular column is fixedly connected to the protective box. One end of the circular column is provided with a guide slope and is inserted into the limiting collar for limiting.

[0012] Preferably, the protective box has hinged double doors on both sides of the opening. A circular rod is fixedly connected to the side of each double door that is far apart from each other. A rotating ring is rotatably connected to the circular rod. A circular base is fixedly connected to the side of the rotating ring. A spherical groove is opened at one end of the circular base. A limiting ball is rolled inside the spherical groove. A fixing rod is fixedly connected to the surface of the limiting ball. A fixing ring is fixedly connected to one end of the fixing rod. The fixing ring is fixedly connected to the corresponding telescopic rod.

[0013] Preferably, a limiting roller is rotatably connected inside the first communicating groove, and a limiting groove is formed on the surface of the limiting roller.

[0014] Preferably, the reciprocating drive mechanism includes a lead screw, which is rotatably connected to one side of the fixed plate and located below the limiting slide rail. A connecting ring is fixedly connected to the bottom of the slider, and the connecting ring is threaded onto the lead screw. A motor is fixedly mounted on the fixed plate, and the output shaft of the motor is fixedly connected to one end of the lead screw.

[0015] Preferably, the limiting slide rail has a through hole, and an electric heating wire is fixedly installed inside the through hole.

[0016] Preferably, the surface of the fixing plate is provided with a plurality of mounting holes, which are respectively located at the upper and lower ends of the limiting slide rail.

[0017] Preferably, a magnetic placement seat is fixedly connected inside the protective box, the charging gun is magnetically limited in the magnetic placement seat, and a cable hook is fixedly connected to the protective box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The U-shaped bracket drives the corresponding limiting shaft to move synchronously, causing the two rotating rods in the same group to rotate crosswise along the rotation connection of the limiting shaft, and causing other rotating rods to rotate in coordination along the corresponding limiting shaft. While the rotating rods rotate, the connecting block slides in coordination within the corresponding limiting frame, thereby moving the limiting frame on the mounting plate and the protective box away from each other, and extending the protective box longitudinally towards the charging port of the electric vehicle. This brings the charging pile body closer to the center of the electric vehicle, ensuring that the charging pile body can effectively approach the charging port whether the electric vehicle is driving forward or backing into the parking space, and reducing the impact of the parking position on the length of the charging cable.

[0020] 2. Power is supplied to the charging pile via a power cable, allowing the pile to continuously supply power to the charging gun along the charging cable. This enables continuous charging after the charging gun is inserted into the charging port of the electric vehicle. The power cable is then gathered by a cable retraction mechanism. The power cable has sufficient length to be released when the protection box moves laterally or longitudinally, and it automatically retracts after the protection box returns to its initial position, thus preventing the power cable from becoming tangled.

[0021] 3. As the telescopic rod tilts, it pulls on the circular base and the rotating ring, causing the rotating ring to rotate along the rotating connection of the circular rod. This pulls on the circular rod, causing the double doors to unfold along the hinge. When the protection box moves away from the mounting plate, the double doors at the opening of the protection box automatically open along the hinge, making it convenient for the user to retrieve the charging gun. After charging is completed and the protection box returns to its initial position, the double doors automatically close, thus protecting the charging pile body inside the protection box.

[0036] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0037] like Figures 1 to 13 The sliding rail type wall-mounted car charging pile shown includes a fixed plate 1, a limiting slide rail 2 fixedly installed on one side of the fixed plate 1, and a slider 3 (such as...) slidably connected to the limiting slide rail 2. Figure 5 As shown), a mounting plate 4 is fixedly connected to one side of the slider 3, and a protective box 5 is provided on one side of the mounting plate 4. The charging pile body 6 is fixedly installed inside the protective box 5 (as shown). Figure 7 As shown), the charging pile body 6 is electrically connected to a power supply cable 7, and the protection box 5 is connected to a longitudinal moving mechanism.

[0038] One end of the fixed plate 1 is fixedly connected to a storage housing 28. A circular plate 29 is disposed inside the storage housing 28. One end of the circular plate 29 is fixedly connected to a connecting shaft 30, which is rotatably connected to the axis on one side of the storage housing 28. A storage sleeve 31 is fixedly connected to the other side of the storage housing 28. A rotary joint 32 is fixedly connected to the other end of the circular plate 29. One end of the rotary joint 32 extends into the storage sleeve 31 and is rotatably connected to a slip ring 33. Multiple insulating rods 34 are fixedly connected to the surface of the slip ring 33. The insulating rods 34 are fixedly connected to the inner wall of the storage sleeve 31. An external cable 35 is electrically connected to the slip ring 33. One end of the external cable 35 passes through the storage sleeve 31 and extends to the outside of the storage sleeve 31. A first connecting groove 36 is provided on the mounting plate 4 (e.g., ...). Figure 9 As shown), a second connecting slot 37 is provided on the housing 28. One end of the power supply cable 7 passes through the protective box 5 and sequentially through the first connecting slot 36 and the second connecting slot 37 before extending into the housing 28 and electrically connecting to the rotary joint 32. A spiral spring 38 is provided at one end of the circular plate 29 near the connecting shaft 30 (as shown). Figure 11 As shown, the two ends of the spiral spring 38 are fixedly connected to the storage housing 28 and the circular plate 29, respectively;

[0039] A recognition probe 14 is fixedly installed at the center of the bottom of the fixed plate 1, and a reciprocating drive mechanism is connected to the slider 3. When working, the existing technology usually uses the lateral sliding of the charging pile on the slide rail to bring the charging pile closer to the charging port of the electric vehicle when charging electric vehicles. However, in actual use, the charging port of the electric vehicle is generally located at the rear of the car. When the user drives into the charging space from the front, the lateral movement of the charging pile can only get closer to one side of the charging port of the electric vehicle, but there is still a long distance between it and the charging port. This results in low adaptability of the single-length charging cable, reducing the convenience of charging. In addition, it is difficult to effectively limit the cable during the movement of the charging pile, which can easily cause the cable to scatter and entangle during the movement, thus affecting the normal movement of the charging pile.This technical solution can solve the above problems. The specific working method is as follows: The fixing plate 1 is fixedly installed on the wall at the rear of the parking space. When the user drives the electric vehicle into the parking space, the recognition probe 14 takes a picture of the vehicle's appearance and uses computer vision to analyze the features, matches the brand database, and determines the brand and model of the electric vehicle, thereby distinguishing the charging port position and parking position of the electric vehicle. Then, the controller connected to the recognition probe 14 controls the reciprocating drive mechanism and hydraulic cylinder 12 to work. The reciprocating drive mechanism causes the slider 3 to slide laterally along the limit slide rail 2, thereby driving the mounting plate 4 and the protection box 5 to move synchronously, so that the charging pile body 6 is close to the charging port side of the electric vehicle. The longitudinal movement mechanism drives the charging pile body 6 to move longitudinally, so that the charging pile body 6 is close to the center of the side of the electric vehicle. Whether the electric vehicle drives into the parking space forward or reverses into the parking space, the charging pile body 6 can effectively approach the charging port. Power is supplied by connecting the external cable 35 to one end outside the storage sleeve 31, so that the external cable 35 and the slip ring 33 are electrically connected, and the power is supplied through the slip ring 33. The rotary connection between the rotary joint 32 and the slip ring 33 electrically connects the rotary joint 32 and the slip ring 33, and also electrically connects the rotary joint 32 and the power supply cable 7, thereby supplying power to the cable 7. When the mounting plate 4 and the protective box 5 move laterally, the power supply cable 7 is pulled along with the movement of the mounting plate 4 and the protective box 5, causing the power supply cable 7, which is wound inside the housing 28, to move outward along the second connecting groove 37, and driving the rotary joint 32 to rotate synchronously. This causes the connecting shaft 30 to rotate along the rotary connection and drive the circular plate 29 to rotate synchronously. As the circular plate 29 rotates, the spiral spring 38 undergoes bending elastic deformation under torque. Furthermore, as the mounting plate 4 and protective box 5 move longitudinally, they continue to pull on the power supply cable 7, increasing the deformation of the spiral spring 38. When the mounting plate 4 and protective box 5 return to their initial positions, the force on the spiral spring 38 gradually decreases and it returns to its initial state. This causes the circular plate 29 and rotary joint 32 to rotate in the opposite direction. During the reverse rotation of the rotary joint 32, the power supply cable 7 is re-wound into the housing 28, preventing entanglement.

[0040] As a further embodiment of the present invention, the longitudinal moving mechanism includes four limiting frames 8, which are respectively fixedly connected to the upper and lower ends of the mounting plate 4 and the protective box 5. Each limiting frame 8 has two connecting blocks 9 slidably connected inside. Multiple sets of rotating rods 10 are arranged between corresponding two limiting frames 8, with two rotating rods in each set. The centers of the two rotating rods 10 in the same set are rotatably connected to a limiting shaft 11. One end of each of two adjacent sets of rotating rods 10 is rotatably connected, and the connecting blocks 9 are rotatably connected to one end of the corresponding rotating rod 10. Two hydraulic cylinders 12 are fixedly mounted on the mounting plate 4. The piston shafts of the hydraulic cylinders 12 penetrate the mounting plate 4 and extend into the corresponding limiting frame 8, where they are fixedly connected to a U-shaped bracket 13. The U-shaped bracket 13 is fixedly connected to the limiting shaft 11 near the mounting plate 4. The charging pile body 6 includes a pile body 601, a charging cable 602, and a charging gun 603. The charging cable 602 is electrically connected to the pile body 601 and the... Between the charging guns 603, one end of the power supply cable 7 is electrically connected to the pile body 601. During operation, the piston shaft of the hydraulic cylinder 12 moves to drive the U-shaped bracket 13 to move, and the U-shaped bracket 13 drives the corresponding limiting shaft 11 to move synchronously, so that the two rotating rods 10 in the same group cross-rotate along the rotation connection of the limiting shaft 11, and so that the other rotating rods 10 cooperate to rotate along the corresponding limiting shaft 11. While the rotating rods 10 rotate, the connecting block 9 cooperates to slide inside the corresponding limiting frame 8 with the rotation of the rotating rods 10, so that the limiting frame 8 on the mounting plate 4 and the protective box 5 move away from each other, and the protective box 5 extends longitudinally towards the charging port of the electric vehicle. The power supply cable 7 supplies power to the pile body 601, so that the pile body 601 can continuously supply power to the charging gun 603 along the charging cable 602, so that continuous charging can be carried out after the charging gun 603 is inserted into the charging port of the electric vehicle.

[0041] As a further embodiment of the present invention, two connecting brackets 15 are fixedly connected to one side of the mounting plate 4. A telescopic rod 16 is rotatably connected inside each connecting bracket 15. Limiting pins 17 are fixedly connected to both sides of the protective box 5. One end of each telescopic rod 16 is rotatably inserted into the corresponding limiting pin 17. During operation, when the protective box 5 moves away from the mounting plate 4 as the rotating rod 10 rotates, one end of the telescopic rod 16 rotates along the rotatable insertion point of the limiting pin 17, while the other end of the telescopic rod 16 rotates along the rotatable connection point of the connecting bracket 15. During the movement of the protective box 5, the telescopic rod 16 extends outwards synchronously. When the maximum moving distance between the protective box 5 and the mounting plate 4 is reached, the telescopic rod 16 simultaneously reaches its maximum extension range. The extended telescopic rod 16 then applies force to both sides of the protective box 5, thereby reducing the supporting pressure on the rotating rod 10 and improving its service life.

[0042] As a further embodiment of the present invention, a limiting collar 18 is fixedly connected to one side of the mounting plate 4 (e.g., Figure 9 As shown, a circular column 19 is fixedly connected to the protective box 5. One end of the circular column 19 has a guide slope and is inserted into the limiting collar 18 for limiting. During operation, when the mounting plate 4 and the protective box 5 are in the initial position, one end of the circular column 19 on the protective box 5 is located inside the limiting collar 18, and the limiting collar 18 limits the circular column 19, thereby supporting the protective box 5 and the charging pile body 6, thereby reducing the supporting pressure of the rotating rod 10 in the initial state.

[0043] As a further embodiment of the present invention, the protective box 5 has hinged double doors 20 on both sides of its opening. A circular rod 21 is fixedly connected to the side of each double door 20 that is far apart from the others. A rotating ring 22 is rotatably connected to the circular rod 21. A circular base 23 is fixedly connected to the side of the rotating ring 22. One end of the circular base 23 has a spherical groove 24 (e.g., ...). Figure 10 As shown, a limiting ball 25 is rolled inside the spherical groove 24. A fixing rod 26 is fixedly connected to the surface of the limiting ball 25. A fixing ring 27 is fixedly connected to one end of the fixing rod 26, and the fixing ring 27 is fixedly connected to the corresponding telescopic rod 16. During operation, when the protective box 5 moves longitudinally away from the mounting plate 4, the telescopic rod 16 extends and tilts. During the tilting process of the telescopic rod 16, the fixing ring 27 and the fixing rod 26 move synchronously, thereby causing the limiting ball 25 to roll inside the spherical groove 24 and move with the telescopic rod 16. The tilt of rod 16 pulls on the circular base 23 and the rotating ring 22, causing the rotating ring 22 to rotate along the rotating connection of the circular rod 21, and pulling on the circular rod 21, causing the double doors 20 to unfold along the hinge. When the protective box 5 moves away from the mounting plate 4, the double doors 20 at the opening of the protective box 5 automatically open along the hinge, making it convenient for the user to take out the charging gun 603. After the charging is completed and the protective box 5 returns to its initial position, the double doors 20 automatically close, thereby protecting the charging pile body 6 inside the protective box 5.

[0044] As a further embodiment of the present invention, a limiting roller 39 is rotatably connected inside the first connecting groove 36, and a limiting groove 40 is formed on the surface of the limiting roller 39 (e.g., ...). Figure 11 (As shown); During operation, the corner position of the power supply cable 7 is limited by the limiting groove 40 on the limiting roller 39. When the mounting plate 4 and the protective box 5 move longitudinally, the power supply cable 7 is pulled and moves along the corner position of the first connecting groove 36. The friction generated by the contact between the limiting roller 39 and the power supply cable 7 causes the limiting roller 39 to rotate, thereby reducing the contact wear at the corner of the power supply cable 7 and preventing the insulation layer of the power supply cable 7 from being damaged.

[0045] As a further embodiment of the present invention, the reciprocating drive mechanism includes a lead screw 41, which is rotatably connected to one side of the fixed plate 1 and located below the limiting slide rail 2. A connecting ring 42 is fixedly connected to the bottom of the slider 3, and the connecting ring 42 is threadedly connected to the lead screw 41. A motor 43 is fixedly installed on the fixed plate 1, and the output shaft of the motor 43 is fixedly connected to one end of the lead screw 41. During operation, the output shaft of the motor 43 rotates to drive the lead screw 41 to rotate, and the slider 3 moves along the sliding connection of the limiting slide rail 2 through the threaded connection between the lead screw 41 and the connecting ring 42, and moves in the opposite direction when the output shaft of the motor 43 rotates in the opposite direction.

[0046] As a further embodiment of the present invention, the limiting slide rail 2 is provided with a through hole 44, and an electric heating wire 45 is fixedly installed inside the through hole 44; during operation, the limiting slide rail 2 is heated by the electric heating wire 45 to keep the limiting slide rail 2 at a certain temperature, so as to prevent the surface of the limiting slide rail 2 from freezing in cold weather, thereby affecting the sliding.

[0047] As a further embodiment of the present invention, the surface of the fixing plate 1 is provided with a plurality of mounting holes 46, which are located at the upper and lower ends of the limiting slide rail 2 respectively. During operation, by opening the mounting holes 46 on the surface of the fixing plate 1, the fixing plate 1 can be conveniently installed on the wall using expansion bolts, thereby completing the installation and fixing of the fixing plate 1.

[0048] As a further embodiment of the present invention, a magnetic placement seat 47 is fixedly connected inside the protective box 5, and the charging gun 603 is magnetically limited in the magnetic placement seat 47. A cable hook 48 is fixedly connected to the protective box 5. During operation, the charging gun 603 is limited and stored by the magnetic placement seat 47, which facilitates the taking and placing of the charging gun 603. The charging cable 602 is stored by the cable hook 48 to prevent the charging cable 602 from being tangled or scattered inside the protective box 5.

[0049] Working principle of this invention:

[0050] The fixing plate 1 is fixedly installed on the wall at the rear of the parking space. When the user drives the electric vehicle into the parking space, the recognition probe 14 takes a picture of the vehicle's appearance and uses computer vision to analyze its features, matches it with the brand database, and determines the brand and model of the electric vehicle. This distinguishes the location of the charging port and the parking position of the electric vehicle. Then, the controller connected to the recognition probe 14 controls the reciprocating drive mechanism and the hydraulic cylinder 12 to work. The reciprocating drive mechanism causes the slider 3 to slide laterally along the limit slide rail 2, thereby driving the mounting plate 4 and the protective box 5 to move synchronously, bringing the charging pile body 6 closer to the charging port side of the electric vehicle. The longitudinal movement mechanism then drives the charging pile body 6 to move longitudinally, bringing the charging pile body 6 closer to the center of the electric vehicle side. This ensures that the charging pile body 6 can effectively approach the charging port whether the electric vehicle is driving forward or backing into the parking space. Power is supplied by connecting the external cable 35 to one end located outside the storage sleeve 31, making the external cable 35 and the slip ring 33 electrically connected. The connection is then established through the rotation between the slip ring 33 and the rotary joint 32. The rotary joint 32 and slip ring 33 are electrically connected, and the connection between the rotary joint 32 and the power supply cable 7 is also electrically connected, thus enabling the power supply cable 7 to supply power. When the mounting plate 4 and the protective box 5 move laterally, the power supply cable 7 is pulled along with the movement of the mounting plate 4 and the protective box 5, thereby causing the power supply cable 7, which is wound inside the housing 28, to move outward along the second connecting groove 37, and driving the rotary joint 32 to rotate synchronously, thereby causing the connecting shaft 30 to rotate along the rotary connection and driving the circular plate 29 to rotate synchronously. When the circular plate 29 rotates, the spiral spring 38 undergoes bending elastic deformation under torque. As the mounting plate 4 and the protective box 5 move longitudinally, the power supply cable 7 continues to be pulled, thereby increasing the degree of deformation of the spiral spring 38. When the mounting plate 4 and the protective box 5 return to their initial positions, the force on the spiral spring 38 gradually decreases and returns to its initial state, thereby driving the circular plate 29 and the rotary joint 32 to rotate in the opposite direction. During the reverse rotation of the rotary joint 32, the power supply cable 7 is re-wound into the housing 28 to prevent the power supply cable 7 from becoming tangled.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by the appended claims and their equivalents is defined.
