Technical Field

[0001] The present invention relates to the technical field of charging piles, and particularly relates to a charging cable lifting mechanism and a charging pile. Background Art

[0002] In recent years, with the gradual increase in new energy vehicles, parking lots are usually equipped with electric vehicle charging piles for charging electric vehicles. Due to the increasing demand for unmanned charging, the length of the charging cable of the charging pile is required to be longer and longer. During the charging process, the charging cable of the charging gun often drags on the ground, and the gun head is placed on the ground for friction, etc., resulting in damage to the charging cable and the charging gun. Therefore, a gun cable automatic lifting device has been designed to improve the friction of the gun head or gun cable on the ground.

[0003] The prior art with the publication number CN113526264A discloses an auxiliary wire winding and unwinding device and an operation method for a charging device, including a motor, a motor controller, a whole machine controller, a wire winding and unwinding device, a micro switch, and a plug gun seat detection switch; the motor controller is connected to the motor, the output end of the motor is connected to the wire winding and unwinding device, and the wire winding and unwinding device is connected to the charging cable; a micro switch is arranged on the charging gun, and a plug gun seat detection switch is arranged in the charging gun socket; the motor controller, the micro switch, and the plug gun seat detection switch are all connected to the whole machine controller.

[0004] However, the existing charging piles still have defects. For example, the charging cable is connected and fixed through a wire clamping clip at the end of the steel wire rope, and the charging cable cannot move relative to the wire clamping clip. The part of the charging cable connected to the wire clamping clip is in a hanging state for a long time, and the charging cable is prone to serious deformation and damage. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above technical deficiencies, and propose a charging cable lifting mechanism to solve the technical problems that in the prior art, the charging cable of the charging pile is connected and fixed through a wire clamping clip at the end of the steel wire rope, the charging cable cannot move relative to the wire clamping clip, the part of the charging cable connected to the wire clamping clip is in a hanging state for a long time, and the charging cable is prone to serious deformation and damage.

[0006] To achieve the above technical purpose, the present invention adopts the following technical solutions: In a first aspect, the present invention provides a charging cable lifting mechanism, including: A wire box, which is provided with a connected wire receiving cavity and a wire outlet groove. The wire receiving cavity is used for storing the charging cable, and the wire outlet groove is used for the charging cable to slide into or out of the wire receiving cavity; and A wire winding and unwinding assembly, including a sliding member. The sliding member is located in the wire receiving cavity and is slidably arranged in the wire box along the length extension direction of the wire outlet groove. The sliding member is configured to connect the charging cable and is used for driving the charging cable to enter or exit the wire receiving cavity when sliding reciprocally.

[0007] In some embodiments, the retractable component further includes a guiding roller rotatably disposed on the sliding member. The guiding roller is used for movably connecting the charging cable and can rotate relative to the sliding member when the charging cable enters and exits the cable storage cavity.

[0008] In some embodiments, a clamping groove is formed along the circumferential side of the guiding roller, and the charging cable is movably clamped in the clamping groove.

[0009] In some embodiments, the sliding member includes a movable seat and baffles disposed on both sides of the movable seat. An activity space is formed between the movable seat and the baffles on both sides, and the guiding roller is located in the activity space.

[0010] In some embodiments, the sliding member further includes a guiding plate. The guiding plate connects the movable seat and the side of the baffle close to the wire outlet groove. The guiding plate is provided with a wire outlet hole for the charging cable to pass through so that the charging cable can pass out of the wire outlet groove.

[0011] In some embodiments, the charging cable lifting mechanism further includes a driving component disposed in the cable box and connected to the sliding member. The driving component can drive the sliding member to slide reciprocally.

[0012] In some embodiments, the driving component includes a motor and a lead screw. The lead screw is rotatably disposed in the cable box and threadedly penetrates the sliding member. The motor is connected to the lead screw and can drive the lead screw to rotate.

[0013] In some embodiments, the driving component includes a cylinder and a telescopic rod. The telescopic rod connects the cylinder and the sliding member.

[0014] In some embodiments, the cable box further includes a guide rod disposed in the cable storage cavity. The guide rod slidably penetrates the sliding member.

[0015] In a second aspect, the present invention further provides a charging pile, including a power supply box, a charging cable, a charging gun, and the above-mentioned charging cable lifting mechanism. The cable box is connected to the power supply box. The input end of the charging cable is connected to the power supply box, and the output end of the charging cable is connected to the charging gun.

[0016] Compared with the prior art, the charging cable lifting mechanism provided by the present invention can be applied to a charging pile. When not in use, the charging cable can be stored in the cable storage cavity. When it is necessary to use the charging cable to charge an electric vehicle, the charging cable can be extended through the cable outlet groove. When the sliding member slides towards the lower position, more charging cable in the cable storage cavity can extend through the cable outlet groove, so as to facilitate charging an electric vehicle at a relatively far distance. After charging is completed, the sliding member can be slid towards the higher position. The sliding member cooperates with the cable outlet groove to drive the charging cable to extend into the cable storage cavity through the cable outlet groove, so as to avoid friction of the charging cable placed on the ground. It can be seen that compared with the prior art, the charging cable of the present invention can change the force-bearing part along with the sliding of the sliding member, and does not always apply force to a certain part of the charging cable, so the charging cable is not easily deformed and damaged.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0019] In order to solve the technical problem in the prior art that the charging cable of a charging pile is connected and fixed by a wire clamping clip at the end of a steel wire rope, the charging cable cannot move relative to the wire clamping clip, and the part of the charging cable connected to the wire clamping clip is in a hanging state for a long time, and the charging cable is easily severely deformed and damaged, the present invention provides a charging cable lifting mechanism, which can continuously change the force-bearing part of the charging cable during the use of the charging cable, so that the charging cable is not easily deformed and has a long service life.

[0020] It should be noted that the charging cable lifting mechanism described in the present invention is used for but not limited to charging piles, etc. For the convenience of description, in the present invention, only the case where the charging cable lifting mechanism is applied to a charging pile is taken as an example for description, and the principle of the charging cable lifting mechanism applied to other types of devices is substantially the same as that applied to a charging pile, and will not be elaborated herein one by one.

[0021] Please refer to Figure 1 , Figure 1Schematic diagram of the charging cable lifting mechanism 100 in an embodiment of the present invention. The charging cable lifting mechanism 100 includes a cable box 1 and a winding and unwinding assembly 2. The cable box 1 is provided with a cable storage cavity 11 and a cable outlet groove 12, and the cable outlet groove 12 communicates with the cable storage cavity 11 and the external air.

[0022] The winding and unwinding assembly 2 includes a sliding member 21. The sliding member 21 is located in the cable storage cavity 11 and is slidably disposed in the cable box 1 along the length extension direction of the cable outlet groove 12. The sliding member 21 is configured to connect to the charging cable 22 and is used to drive the charging cable 22 to enter or exit the cable storage cavity 11 when reciprocatingly sliding. When the charging cable 22 is needed, the sliding member 21 can be controlled to slide downward to release the charging cable 22. The charging cable 22 can continuously pass through the cable outlet groove 12 and extend outwards from the cable box 1 to facilitate charging the electric vehicle.

[0023] The winding and unwinding assembly 2 further includes the above-mentioned charging cable 22. The charging cable 22 is movably connected to the sliding member 21 and passes through the cable outlet groove 12. The sliding member 21 is located in the cable storage cavity 11 and is slidably disposed in the cable box 1 along the length extension direction of the cable outlet groove 12. The sliding member 21 can drive the charging cable 22 to enter or exit the cable storage cavity 11 when reciprocatingly sliding.

[0024] In this embodiment, the cable storage cavity 11 can be used to store the charging cable 22, and the cable outlet groove 12 communicates with the cable storage cavity 11. Therefore, the charging cable 22 in the cable storage cavity 11 can be released to the outside through the cable outlet groove 12 to facilitate charging the electric vehicle. When charging is not required, the charging cable 22 can be retracted into the cable storage cavity 11 through the cable outlet groove 12 to avoid abrasion of the charging cable 22 on the ground when not in use. The winding and unwinding of the charging cable 22 are specifically controlled by manipulating the reciprocating sliding of the sliding member 21. When charging is needed, the sliding member 21 can be slid towards the bottom of the cable storage cavity 11, and the charging cable 22 can be gradually released during the process of the sliding member 21 sliding towards the bottom of the cable storage cavity 11. When charging is not required, the sliding member 21 can be slid towards the top of the cable storage cavity 11, and the sliding member 21 drives the charging cable 22 to enter the cable storage cavity 11 to store the charging cable 22. It can be seen that the charging cable 22 of the present invention does not need to use a traditional reel anymore. Only by controlling the reciprocating sliding of the sliding member 21 can the charging cable 22 be quickly wound and unwound, which is convenient to use. In addition, the force-bearing point of the charging cable 22 is mainly on the sliding member 21, and the force-bearing part of the charging cable 22 will continuously change during the winding and unwinding process, making the charging cable 22 not easily deformed and having a long service life.

[0025] In one of the embodiments, please refer to Figure 2The retractable assembly 2 further includes a guide roller 23, which is rotatably disposed on the sliding member 21. The charging cable 22 is connected to the guide roller 23 and can drive the guide roller 23 to rotate when entering and exiting the retractable cavity 11. In this embodiment, the guide roller 23 can support the charging cable 22, and the guide roller 23 can rotate during the retractable process of the charging cable 22, so as to guide the charging cable 22, so that the charging cable 22 can be retracted more smoothly, and the cable jam can be avoided.

[0026] In one embodiment, see Figure 2 The guide roller 23 has a slot 231 formed along its circumference, and the charging cable 22 is movably mounted in the slot 231. In this embodiment, the width of the slot 231 formed by the guide roller 23 is adapted to the diameter of the charging cable 22, so that the slot 231 can limit the charging cable 22, and the charging cable 22 can stably reciprocate along the slot 231. Figure 2 In the illustrated embodiment, only one guide roller 23 is provided, and the guide roller 23 is rotatably provided on a bracket 24, and the bracket 24 is provided on the sliding member 21. The charging cable 22 moves along the top of the guide roller 23 to enter and exit the cable outlet slot 12. Figure 3 In the illustrated embodiment, two guide rollers 23 are provided, and both guide rollers 23 are rotatably disposed on the bracket 24, and the two guide rollers 23 are disposed one above the other, with a wire passing space 25 formed between the two. The wire passing space 25 is used for the charging cable 22 to pass through, and the two guide rollers 23 can simultaneously limit the charging cable 22 up and down, so that the charging cable 22 can be more stable during the process of entering and exiting, and will not separate from the guide rollers 23. In addition, during the process of entering and exiting, the charging cable 22 can simultaneously drive the two guide rollers 23 to rotate, and the two guide rollers 23 can simultaneously guide the charging cable 22, so that the charging cable 22 can enter and exit more smoothly, and the user experience is good.

[0027] In one embodiment, see Figure 3 The sliding member 21 includes a movable seat 211 and baffles 212 disposed on both sides of the movable seat 211. An active space 213 is formed between the movable seat 211 and the baffles 212 on both sides. The guide roller 23 is located in the active space 213. The charging cable 22 passes through the movable seat 211 and is located in the active space 213. In this embodiment, the baffles 212 disposed on both sides of the movable seat 211 can be used to limit the charging cable 22 so that the charging cable 22 can stably enter and exit the active space 213.

[0028] The movable seat 211 is provided with a wire entry hole 214, which is used for the charging wire 22 of the wire receiving chamber 11 to slide through, so that the charging wire 22 of the wire receiving chamber 11 can slide through the wire entry hole 214. The wire entry hole 214 can limit the charging wire 22, so that the sliding member 21 can stably drive the charging wire 22 to be retracted and released when sliding.

[0029] In one embodiment, refer to Figure 3 , the sliding member 21 further includes a guiding plate 215. The guiding plate 215 is connected to one side of the movable seat 211 and the baffle 212 close to the wire outlet groove 12. The guiding plate 215 is provided with a wire outlet hole 216, and the charging wire 22 passes through the wire outlet hole 216 and the wire outlet groove 12 in sequence. In this embodiment, the wire outlet hole 216 provided on the guiding plate 215 can limit and guide the charging wire 22, so that the charging wire 22 can stably enter and exit through the wire outlet hole 216.

[0030] In one embodiment, refer to Figure 1 , the charging wire lifting mechanism further includes a driving assembly 3. The driving assembly 3 is arranged in the wire box 1 and connected to the sliding member 21. The driving assembly 3 can drive the sliding member 21 to slide reciprocally. In this embodiment, the driving assembly 3 is used to provide a power source for the reciprocal sliding of the sliding member 21, so as to drive the sliding member 21 to slide reciprocally and drive the charging wire 22 to wind and unwind.

[0031] In one embodiment, refer to Figure 1 , the driving assembly 3 includes a motor 31 and a lead screw 32. The lead screw 32 is rotatably arranged in the wire box 1 and threadedly penetrates through the sliding member 21. The motor 31 is connected to the lead screw 32 and can drive the lead screw 32 to rotate. In this embodiment, the movable seat 211 is provided with a threaded hole 217, and the lead screw 32 threadedly penetrates through the threaded hole 217. When the motor 31 is working, it can drive the lead screw 32 to rotate, so that the lead screw 32 drives the sliding member 21 to slide reciprocally through the thread. By driving the sliding member 21 to slide with the lead screw 32 in a threaded manner, the position of the sliding member 21 can be adjusted more precisely, and the charging wire 22 can be precisely wound and unwound. In other embodiments, the motor 31 and the lead screw 32 can also be replaced by a cylinder and a telescopic rod. The telescopic rod is connected to the cylinder and the sliding member 21. When the cylinder is working, it can drive the telescopic rod to extend and retract, and the telescopic rod drives the sliding member 21 to slide reciprocally.

[0032] In one embodiment, refer to Figure 1 , the wire box 1 further includes a guide rod 13 arranged in the wire winding cavity 11. The guide rod 13 slidably penetrates through the sliding member 21. When the sliding member 21 slides reciprocally, it can slide along the guide rod 13. The guide rod 13 can guide the sliding member 21, so that the sliding member 21 can slide reciprocally stably, and thus the charging wire 22 can be wound and unwound stably.

[0033] The wire box 1 further includes a limiting member disposed at the bottom of the wire receiving cavity 11. The limiting member is connected to the charging wire 22 and is used to limit the movement of the connection part between the charging wire 22 and the limiting member. In this embodiment, by using the limiting member to fix the bottom of the charging wire 22, the charging wire 22 can be limited, preventing the charging wire 22 from detaching from the power source under excessive pulling force. The limiting member can be composed of two semi-circular clamps. The two clamps clamp the charging wire 22 and then fixedly install it on the wire box 1, thus fixing the bottom of the charging wire 22.

[0034] Please refer to Figure 4 Secondly, the present invention also provides a charging pile 200, which includes a power supply box 4, a charging gun 5, and the above-mentioned charging wire lifting mechanism 100. The wire box 1 is connected to the power supply box 4. The input end of the charging wire 22 is connected to the power supply box 4, and the output end of the charging wire 22 is connected to the charging gun 5. In this embodiment, the power supply box 4 has a power source, and the input end of the charging wire 22 is connected to the power source to supply power to the charging wire 22. When the output end of the charging wire 22 is inserted into an electric vehicle, it can charge the electric vehicle. When it is necessary to adjust the length of the charging wire 22 extending out of the wire box 1, the sliding member 21 of the charging wire lifting mechanism 100 can be controlled to slide up and down. Specifically, an operation panel can be set outside the power supply box 4, and the user can manually operate the operation panel to control the motor 31 to drive the lead screw 32 to rotate forward or backward, thereby controlling the reciprocating sliding of the sliding member 21. When the sliding member 21 slides towards the bottom of the wire box 1, the charging wire 22 in the wire receiving cavity 11 can extend out through the wire outlet groove 12 more, so as to charge an electric vehicle at a farther distance. After charging is completed, the sliding member 21 can be slid towards the higher position. The sliding member 21 cooperates with the wire outlet groove 12 to drive the charging wire to extend into the wire receiving cavity 11 through the wire outlet groove 12, so as to avoid the charging wire rubbing on the ground. It can be seen that compared with the prior art, the charging wire 22 of the present invention can change the force-bearing part along with the sliding of the sliding member 21, and will not always apply force to a certain part of the charging wire 22, and the charging wire is not easily deformed and damaged.

[0035] For a better understanding of the present invention, the following is a detailed description of the technical solution of the present invention in conjunction with Figures 1 to 4 : The charging wire lifting mechanism 100 provided by the present invention can be applied to the charging pile 200. When the charging wire 22 is not in use, it can be stored in the wire receiving cavity 11. When it is necessary to use the charging wire 22 to charge an electric vehicle, the charging wire 22 can be extended through the wire outlet groove 12. When the sliding member 21 slides towards the lower part of the wire box 1, more of the charging wire 22 in the wire receiving cavity 11 can extend out through the wire outlet groove 12, so as to charge an electric vehicle at a farther distance. After charging is completed, the sliding member 21 can be slid towards the higher position. The sliding member 21 cooperates with the wire outlet groove 12 to drive the charging wire to extend into the wire receiving cavity 11 through the wire outlet groove 12, so as to avoid the charging wire rubbing on the ground. It can be seen that compared with the prior art, the charging wire 22 of the present invention can change the force-bearing part along with the sliding of the sliding member 21, and will not always apply force to a certain part of the charging wire 22, and the charging wire is not easily deformed and damaged.
