Description

Technical Field

[0001] The present invention relates to the technical field of charging guns, and specifically to a charging gun based on a visual-pressure dual-feedback plugging and calibration mechanical device. Background Art

[0002] A charging gun, that is, a charging gun for new energy vehicles, is a key device connecting new energy vehicles with charging piles or charging stations, responsible for transmitting electric energy from the power source to the battery of the new energy vehicle. Its core function is to achieve safe and efficient electric energy transmission, ensuring that new energy vehicles can quickly and stably replenish their power. The docking of traditional charging guns is mostly achieved by manual docking, and some vehicles also adopt mechanical control methods to control the automatic docking of the charging gun for subsequent charging operations (such as Tesla V4 Supercharger, NIO Power Swap Station) generally using mechanical automatic adjustment to improve the accuracy, efficiency, and safety of the charging gun docking.

[0003] Prior Art One (a Chinese patent with publication number CN206313168U and publication date July 7, 2017) A charging gun includes a charging gun body, a charging gun handle provided at one end of the charging gun body, and a charging gun interface provided at the other end of the charging gun body and away from the charging gun handle; three first pins, two second pins, and three third pins are provided in the charging gun interface; the three first pins are adjacent to each other and arranged in an isosceles triangle; the two second pins are located outside the isosceles triangle; the two second pins are respectively between two first pins on the two waists of the isosceles triangle, and each second pin is tangent to the first pin close to the base of the isosceles triangle; the two third pins are respectively between a second pin and the first pin at the apex of the isosceles triangle; the other third pin is between the two first pins on the base of the isosceles triangle. And Prior Art Two (a Chinese patent with publication number CN222563108U and publication date March 4, 2025) A charging gun includes a charging gun body and a lock sleeve. The charging gun body includes a charging gun main body and an adapter. The adapter is detachably connected to the charging gun main body. A buckle is provided on the charging gun main body, and the buckle can be engaged with the adapter to lock the adapter connected to the charging gun main body to the charging gun main body; the lock sleeve is sleeved on the adapter, and a protruding cavity shell is formed on the lock sleeve, and a locking member is detachably assembled on the protruding cavity shell. When the locking member is assembled to the protruding cavity shell, the locking member can be connected to the protruding cavity shell, and at least part of the locking member is arranged on the side of the buckle away from the adapter and abuts against the buckle for limiting the buckle to the adapter. The locking member connected to the protruding cavity shell abuts against the buckle on the charging gun main body, so that the buckle on the charging gun main body can always be pressed by the locking member on the adapter to prevent the adapter from shifting on the charging gun main body and ensure the normal operation of the charging gun.

[0004] Although fast docking of the charging gun can be achieved in the prior art, most of the docking methods are manual, and the docking situation cannot be feedback. During docking, the phenomenon of misalignment may occur, thus affecting the normal use of the charging port.

[0005] Therefore, we propose a charging gun based on a visual-pressure dual-feedback plugging and calibration mechanical device to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of the present invention is to provide a charging gun based on a visual-pressure dual-feedback plugging and calibration mechanical device to solve the problem that the charging gun on the current market cannot feedback its docking situation during docking, and the phenomenon of misalignment may occur during docking, thus affecting the normal use of the charging port as mentioned in the above background technology.

[0007] To achieve the above purpose, the present invention provides the following technical solutions: A charging gun based on a visual-pressure dual-feedback plugging and calibration mechanical device, including a charging gun body and a moving frame arranged at the top of the place to be charged. An adjustment box electrically connected to the charging gun body through a docking wire is slidably arranged inside the moving frame, and an adjustment member for connecting the charging gun body is arranged below the adjustment box. The upper side of the end of the adjustment member is fixedly connected with an observation box, and a main lens and a swinging mechanism are arranged outside the observation box. The swinging mechanism drives the auxiliary lens it contains to swing to achieve precise calibration of the plugging position. At the same time, a strain gauge for feedback calibration of the plugging pressure is arranged between the front end of the observation box and the docking port of the charging gun body, and the strain gauge is provided with an observation point. A protection mechanism for protecting the main lens is arranged on the side of the main lens. A magnetic locking tongue is arranged at the end of the charging gun body, and the magnetic locking tongue deforms through the operation of the protection mechanism to realize the docking limit operation of the charging gun body.

[0008] Preferably, the protection mechanism includes a telescopic rod, the telescopic rod is fixedly connected to the upper surface of the observation box, the end of the telescopic rod is fixedly connected with a pressing plate, and a rotating rod is hinged to the side of the pressing plate. A sliding groove is opened on the front side of the observation box, a slider is nested and connected inside the sliding groove, a linkage plate is fixedly connected to the outside of the slider, and a protection plate is fixedly connected to the inside of the linkage plate. The upper side of the protection plate is hinged to the other end of the rotating rod.

[0009] Preferably, the slider forms a sliding structure with the sliding groove through the linkage plate, the rotating rod forms a rotating structure with the protection plate through the pressing plate, and two groups of protection plates are symmetrically distributed about the center point of the main lens.

[0010] Preferably, a limiting rod is fixedly connected to the side of the upper surface of the observation box. The pressing plate is nested on the outer side of the limiting rod, and an airbag is fixedly connected between the lower surface of the pressing plate and the upper surface of the observation box.

[0011] Preferably, the swinging mechanism includes a communicating pipe. The communicating pipe is disposed through the side of the airbag, and an auxiliary pipe is disposed through between the two communicating pipes. An adjusting shaft is nested inside the auxiliary pipe. A cleaning pipe is disposed through the side of the lower communicating pipe. A fan is fixedly connected to the outer side of the adjusting shaft. A fixing plate is fixedly connected to the side of the adjusting member. A swinging plate is rotatably connected to the inner side of the fixing plate. An adjusting groove is formed in the middle of the upper side of the swinging plate. At the same time, an auxiliary lens for assisting in imaging is fixedly connected to the lower end of the swinging plate. A turntable is fixedly connected to the outer end of the adjusting shaft. A sliding rod is fixedly connected to the outer edge of the turntable. The sliding rod is nested inside the adjusting groove.

[0012] Preferably, the adjusting shaft and the auxiliary pipe form a rotating structure through the fan, and the fan is located at the docking center position of the auxiliary pipe.

[0013] Preferably, the sliding rod and the adjusting groove form a sliding structure through the turntable. The swinging plate and the fixing plate form a rotating structure through the sliding rod. Two groups of auxiliary lenses are symmetrically arranged on the left and right directly below the main lens.

[0014] Preferably, electric contact pieces are fixedly connected to the inner wall of the chute and the side of the slider. An electromagnetic block is fixedly connected above the end of the charging gun body. The electromagnetic block is electrically connected to the electric contact piece. A magnetic locking tongue is also fixedly connected above the end of the charging gun body.

[0015] Preferably, a trapezoidal protrusion is provided at the end of the magnetic locking tongue. The magnetic locking tongue is elastically structured. The magnetism of the magnetic locking tongue is opposite to that of the electromagnetic block.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The adjustment box drives the adjusting member to adjust to a position adapted to the vehicle body, and controls the charging gun body to move to the corresponding charging port. The positions of the vehicle body and the charging port are scanned by the main lens and the auxiliary lens to obtain the three-dimensional coordinates of the charging port for subsequent insertion. The pressure during insertion can be monitored in real time through the strain gauge, and the posture of the gun head of the charging gun body is further adjusted. By fusing the visual pose data and the pressure gradient data, the optimal insertion trajectory is output, thereby completing the precise insertion operation of the charging gun body.

[0017] The pressure plate drives the rotating rod to rotate synchronously to both sides, so that the protective plates slide to both sides. When the protective plates slide and expand to both sides, the protective plates do not block the main lens when sliding, and the main lens can perform scanning operations. When scanning is not required, the two sets of protective plates are adjacent to each other and block the main lens, thereby protecting the main lens and preventing damage to the main lens.

[0018] When the pressure plate moves downward, it can squeeze the airbag, and the gas inside the airbag is ejected outward through the auxiliary tube. The ejected gas blows toward the auxiliary lens, thereby cleaning the dust on the surface of the auxiliary lens, so that the auxiliary lens can collect data more clearly.

[0019] When the gas passes through the auxiliary pipe, it will blow the fan, thereby driving the adjusting shaft to rotate through the fan. At this time, the turntable rotates, causing the slide bar to resist the swing plate, so that the swing plate drives the auxiliary lens set at the lower end to swing synchronously, realizing data collection at different positions over a wide range, reducing the error in collecting the three-dimensional coordinate position data of the charging port, and facilitating the subsequent plug-in operation.

[0020] When the protective plate is unfolded to both sides, the two groups of electrical contact pieces arranged between the sides of the slide groove and the slider contact each other. At this time, the electromagnetic block is energized and magnetic, and the magnetic lock tongue bends toward the side of the electromagnetic block. At this time, the charging gun body can be docked with the charging port. When the two groups of electrical contact pieces are not in contact, the electromagnetic block is not magnetic at this time, and the magnetic lock tongue is reset. The protruding position set at the lower end of the magnetic lock tongue can be engaged with the charging port, thereby reducing the occurrence of loosening of the charging gun body.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1: As Figure 1 , Figure 2 and Figure 9 shown in the technical solution, the present invention provides the following technical solution: A charging gun based on a vision-pressure dual-feedback plugging calibration mechanical device, which discloses a main lens 8, an auxiliary lens 23 and a strain gauge 29 to realize the dual feedback of visual pose data and pressure gradient data: a charging gun body 4 and a moving frame 1 arranged at the top of the place to be charged. An adjusting box 2 electrically connected to the charging gun body 4 through a docking wire 5 is slidably arranged inside the moving frame 1, and an adjusting member 3 for connecting the charging gun body 4 is arranged below the adjusting box 2. The upper side of the end of the adjusting member 3 is fixedly connected with an observation box 6, and a swinging mechanism is arranged outside the observation box 6. The swinging mechanism drives the included auxiliary lens 23 to swing to realize accurate calibration of the plugging position. At the same time, a strain gauge 29 for feedback calibration of the plugging pressure is arranged between the front end of the observation box 6 and the docking port of the charging gun body 4, and the strain gauge 29 is provided with an observation point 30. A protection mechanism for protecting the main lens 8 is arranged on the side of the main lens 8. A magnetic lock tongue 32 is arranged at the end of the charging gun body 4. The magnetic lock tongue 32 generates deformation through the operation of the protection mechanism to realize the docking limit operation of the charging gun body 4.

[0025] The adjustment box 2 can slide along the moving frame 1, so as to adjust the adjusting member 3 to a position adapted to the vehicle body. At this time, the adjusting member 3 controls the charging gun body 4 to move to the corresponding charging port. Through the mutual cooperation and scanning of the main lens 8 and the auxiliary lens 23, the positions of the vehicle body and the charging port are scanned. And the image processing unit arranged inside the adjustment box 2 identifies the position of the charging port, obtains the three-dimensional coordinates of the charging port, and synchronizes the algorithm calculation to cooperate with the adjusting member 3 to adjust the relative pose of the charging gun body 4 and the charging port for plugging. At the same time, a strain gauge 29 is arranged at the end of the charging gun body 4. The strain gauge 29 can monitor the plugging pressure in real time, and the observation point 30 arranged at the end of the strain gauge 29 receives the distribution of the pressure magnitude more carefully. When the strain gauge 29 senses uneven pressure distribution, the control system arranged inside the adjustment box 2 controls the adjusting member 3 to further adjust the gun head posture of the charging gun body 4. By fusing the visual pose data and the pressure gradient data with high frequency and low precision, the optimal plugging trajectory is output, so as to complete the precise plugging operation of the charging gun body 4.

[0026] Embodiment 2: As Figure 3 , Figure 4 , Figure 8 and Figure 10 shown in the technical solution, the present invention provides the following technical solution: A charging gun based on a vision-pressure dual-feedback plugging calibration mechanical device discloses a protection mechanism. The protection mechanism protects the main lens 8 to prevent the main lens 8 from being damaged: The protection mechanism includes a telescopic rod 9. The telescopic rod 9 is fixedly connected to the upper surface of the observation box 6, and the end of the telescopic rod 9 is fixedly connected to a pressing plate 10. And a rotating rod 16 is hinged to the side of the pressing plate 10. A sliding groove 14 is opened on the front side of the observation box 6, and a slider 28 is nested inside the sliding groove 14. And a linkage plate 13 is fixedly connected to the outer side of the slider 28. At the same time, a protection plate 7 is fixedly connected to the inner side of the linkage plate 13. The upper side of the protection plate 7 and the other end of the rotating rod 16 are hinged to each other. The slider 28 forms a sliding structure with the sliding groove 14 through the linkage plate 13. The rotating rod 16 forms a rotating structure with the protection plate 7 through the pressing plate 10. And two groups of protection plates 7 are symmetrically distributed about the center point of the main lens 8. Electric contact pieces 15 are fixedly connected to the inner wall of the sliding groove 14 and the side of the slider 28. An electromagnet 31 is fixedly connected above the end of the charging gun body 4. And the electromagnet 31 is electrically connected to the electric contact piece 15. And a magnetic locking tongue 32 is also fixedly connected above the end of the charging gun body 4. A trapezoidal protrusion is arranged at the end of the magnetic locking tongue 32. And the magnetic locking tongue 32 is arranged in an elastic structure. And the magnetism of the magnetic locking tongue 32 is opposite to the magnetism of the electromagnet 31.

[0027] When it is necessary to scan the position of the vehicle body and the charging port, the telescopic rod 9 is activated. At this time, the telescopic rod 9 can drive the pressing plate 10 to move downward, so as to drive the rotating rod 16 to rotate synchronously to both sides through the pressing plate 10. Under the pushing action of the rotating rod 16, the protective plate 7 can slide synchronously to both sides. When the protective plate 7 slides, it will drive the slider 28 to slide along the inside of the chute 14. By limiting the slider 28 through the chute 14, the stability of the protective plate 7 during sliding can be further improved. When the protective plate 7 slides and unfolds to both sides, the protective plate 7 does not block the main lens 8 during sliding, and the main lens 8 can perform scanning operations. When scanning is not required, the two protective plates 7 are adjacent to each other and block the main lens 8, thereby protecting the main lens 8 and preventing the main lens 8 from being damaged. When the protective plate 7 unfolds to both sides, the slider 28 will move towards the side of the chute 14. At this time, the two electric contact pieces 15 arranged between the side of the chute 14 and the side of the slider 28 are in contact with each other, so that the electromagnetic block 31 electrically connected to them is energized and has magnetism. The magnetic electromagnetic block 31 will attract the magnetic lock tongue 32 at this time, so that the magnetic lock tongue 32 bends towards the electromagnetic block 31. At this time, the charging gun body 4 can be docked with the charging port. After the docking is completed, the two protective plates 7 move towards each other and protect the main lens 8. The two electric contact pieces 15 are not in contact with each other, and the electromagnetic block 31 does not have magnetism at this time. The magnetic lock tongue 32 is reset. The convex position provided at the lower end of the magnetic lock tongue 32 can be used to engage the charging port, so as to reduce the occurrence of the charging gun body 4 loosening.

[0028] Embodiment 3: As Figures 5 - 7The technical scheme shown in the invention provides the following technical scheme: a charging gun based on a visual-pressure dual feedback plug-in calibration mechanical device discloses a swing mechanism, which drives the auxiliary lens 23 to swing to realize data collection at different positions in a wide range: a limit rod 12 is fixedly connected to the side of the upper surface of the observation box 6, a pressure plate 10 is nested and connected to the outside of the limit rod 12, and an airbag 11 is fixedly connected between the lower surface of the pressure plate 10 and the upper surface of the observation box 6, the swing mechanism includes a connecting pipe 17, the connecting pipe 17 is arranged through the side of the airbag 11, and an auxiliary pipe 18 is arranged through the two groups of connecting pipes 17, and an adjusting shaft 21 is nested inside the auxiliary pipe 18, and a dust cleaning pipe 19 is arranged through the side of the lower connecting pipe 17, and a fan is fixedly connected to the outside of the adjusting shaft 21 26, a fixed plate 20 is fixedly connected to the side of the adjusting member 3, and a swing plate 22 is rotatably connected to the inner side of the fixed plate 20, and an adjusting slot 25 is opened in the middle of the upper side of the swing plate 22, and an auxiliary lens 23 for auxiliary video recording is fixedly connected to the lower end of the swing plate 22, a turntable 27 is fixedly connected to the outer end of the adjusting shaft 21, and a slide bar 24 is fixedly connected to the outer edge of the turntable 27, and the slide bar 24 is nested in the adjusting slot 25, the adjusting shaft 21 forms a rotating structure with the auxiliary tube 18 through the fan 26, and the fan 26 is located at the docking center of the auxiliary tube 18, the slide bar 24 forms a sliding structure with the adjusting slot 25 through the turntable 27, the swing plate 22 forms a rotating structure with the fixed plate 20 through the slide bar 24, and two groups of auxiliary lenses 23 are symmetrically arranged about the left and right sides of the main lens 8.

[0029] When the pressing plate 10 moves downward, it can synchronously slide along the limiting rod 12 to stably squeeze the airbag 11. The gas inside the squeezed airbag 11 will be transported to the auxiliary pipe 18 through the connecting pipe 17 and ejected outward through the auxiliary pipe 18. The ejected gas blows toward the auxiliary lens 23, thereby cleaning the dust on the surface of the auxiliary lens 23, so that the auxiliary lens 23 can collect data more clearly. When the airbag 11 is supplied to the inside of the cleaning pipe 19 through the connecting pipe 17, it will pass through the auxiliary pipe 18. At this time, the gas will blow the auxiliary pipe 18. The fan 26 is arranged, so that the adjusting shaft 21 is driven to rotate by the fan 26. When the adjusting shaft 21 is rotating, the turntable 27 is synchronously driven to rotate, thereby driving the slide bar 24 to slide inside the adjusting slot 25 provided on the swing plate 22. When the slide bar 24 slides, it resists the swing plate 22, so that the swing plate 22 swings left and right, driving the auxiliary lens 23 provided at the lower end to swing synchronously, thereby realizing data collection at different positions in a wide range, reducing the error in the collection of the three-dimensional coordinate position data of the charging port, and facilitating the subsequent plug-in operation.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
