[0024] In the application, the new energy automobile charging robot of the application embodiment further comprises a charging gun 2 coiled on the gun hanging disc 11 and electrically connected with the charging robot body 1. The charging gun 2 comprises a gun body 21, a plurality of styles of gun heads 22 are detachably inserted at one end of the gun body 21, a power supply contact 23 is arranged at one end of the gun body 21 inserted with the gun head 22, the power supply contact 23 is electrically connected with the gun head 22, a gun handle 24 is fixedly connected on the gun body 21, and the gun handle 24 is hung on the gun stock 12. A quick connection assembly 3 for fixing the gun head 22 is arranged between the gun body 21 and the gun head 22. The quick connection assembly 3 comprises a quick connection ring 31 fixedly sleeved on the gun head 22 and a connection assembly 32 slidably arranged on the gun body 21. The connection assembly 32 itself has radial elastic expansion and contraction capability. The gun head 22 can be fixed or detached through the radial elastic expansion and contraction of the connection assembly 32.

[0025] Specifically, asFigure 7 As shown in the drawings, one end of the gun body 21 is provided with a quick-connection socket 211, and two positioning grooves 212 are symmetrically arranged in the quick-connection socket 211.

[0026] As shown in the drawings, Figure 7 As shown in the drawings, a rotating groove 213 is arranged on the outer wall of the gun body 21. Specifically, the rotating groove 213 is divided into an inner part and an outer part. The inner part is a complete annular shape, and the outer part is a partial arc shape. The axial width of the inner part is greater than that of the outer part. Further, as shown in the drawings, Figure 9 As shown in the drawings, a through hole 214 is arranged on the rotating groove 213.

[0027] As shown in the drawings, Figure 7 and Figure 8 As shown in the drawings, a power supply cavity 215 is coaxially arranged in the interior of the quick-connection socket 211. The power supply contact 23 is arranged in the power supply cavity 215 and is electrically connected with the cable.

[0028] It can be understood that the gun head 22 is inserted into the quick-connection socket 211, and one end of the gun head 22 inserted into the quick-connection socket 211 is provided with an electrical contact 221 abutting against the power supply contact 23. It should be noted that after the gun head 22 is inserted into the quick-connection socket 211, the electrical contact 221 abuts against the power supply contact 23 to form an electrical connection.

[0029] As shown in the drawings, Figures 5-7 As shown in the drawings, the quick-connection ring 31 is fixedly sleeved on the gun head 22. The quick-connection ring 31 is inserted into the quick-connection socket 211. Two positioning strips 311 symmetrically arranged on the outer wall of the quick-connection ring 31 are in sliding fit with the positioning grooves 212. It can be understood that by inserting the positioning strips 311 into the positioning grooves 212, it can be ensured that the gun head 22 will not rotate relative to the gun body 21 after the gun head 22 is inserted into the gun body 21.

[0030] It should be noted that, as shown in the drawings, Figure 6 and Figure 10 As shown in the drawings, the position of the positioning strip 311 corresponding to the through hole 214 is provided with a quick-connection hole 312.

[0031] As shown in the drawings, Figure 7 , Figure 9 and Figure 10 As shown in the drawings, the connecting assembly 32 includes a sliding block 321 sliding in the rotating groove 213. A positioning rod 322 is slidingly inserted into the sliding block 321. A tension spring 323 is sleeved on the positioning rod 322. One end of the positioning rod 322 is fixedly connected with a knob 324.

[0032] It should be noted that the inner side of the slider 321 is symmetrically provided with a flange 325 at both ends, the flange 325 and the inner side of the rotating groove 213 are slidingly matched, the outer side of the slider 321 and the outer side of the rotating groove 213 are slidingly matched, so it can be understood that the radial position of the slider 321 in the rotating groove 213 can be ensured by the sliding matching of the flange 325 and the inner side of the rotating groove 213, and the slider 321 is prevented from being separated from the rotating groove 213.

[0033] Further, the outer side of the slider 321 is provided with a top recess 326, the inner side of which is provided with a limiting groove 329, the inner end of the positioning rod 322 is coaxially fixed with a limiting ring 327, and the inner side of the knob 324 is provided with a bottom recess 328; wherein the limiting ring 327 is slidingly matched with the quick connecting hole 312, the through hole 214 and the limiting groove 329 respectively; the two ends of the tension spring 323 are fixedly connected with the top recess 326 and the bottom recess 328 respectively.

[0034] It can be understood that when it is necessary to replace the gun head 22 to adapt to different new energy automobile charging ports (at this time the original gun head 22 is inserted into the gun body 21), the knob 324 is pulled outward, the positioning rod 322 drives the fiber ring 327 to slide from the quick connecting hole 312, the through hole 214 to the limiting groove 329, at this time the positioning rod 322 and the limiting ring 327 are separated from the limiting of the quick connecting ring 31 and the gun body 21, and the knob 324 is rotated to rotate the slider 321 along the rotating groove 213, and then the hand is released, in this process, the tension spring 323 is stretched under the radial force of the knob 324 outward, after the hand is released, the radial tension will be lost, so the tension spring 323 will reset until the limiting ring 327 abuts against the inner side of the rotating groove 213, and the entire connecting assembly 32 is positioned in the rotating groove 213, then the gun head 22 is pulled out, the gun head 22 (a storage cabin can be provided on the inner side or outer wall of the charging robot body 1 to store a plurality of different styles of gun heads 22 for standby) is taken out, the quick connecting ring 31 on the gun head 22 is inserted into the quick connecting port 211, and the positioning strip 311 is inserted into the positioning groove 212, so that the gun head 22 is prevented from rotating relative to the gun body 21, then the knob 324 is rotated in the opposite direction, until the limiting ring 327 on the knob 324 is moved to the through hole 214, and is inserted into the quick connecting hole 312 under the tension of the tension spring 323, the axial positioning of the gun head 22 is completed, at this time the power contact 221 on the gun head 22 and the power supply contact 23 on the gun body 21 are abutted, so that the electrical connection between the gun head 22 and the gun body 21 is formed, then the charging gun 2 is inserted into the charging port of the new energy automobile.

[0035] In the related art, after the charging gun 2 is plugged into the vehicle charging port, a locking device is usually used to form a locking relationship between the charging gun 2 and the vehicle charging port to prevent the charging gun 2 from falling off and causing the vehicle charging to fail. However, the locking device in the prior art needs a separate part to realize the locking function, and users often forget to unlock and directly plug in the charging gun 2 during use, which can cause damage to the vehicle charging port and the charging gun 2.

[0036] In some embodiments of the present application, as shown in Figures 11-15 The locking assembly 4 is provided on the outer wall of the end of the gun body 21 to which the gun head 22 is plugged, and the locking assembly 4 includes a locking groove 41, a rotating ring 42, and a locking block 43. The locking groove 41 is in communication with the inner side of the rotating groove 213, the rotating ring 42 is rotationally arranged on the inner side of the rotating groove 213 and is fixedly connected to the two ends of the sliding block 321, and the locking block 43 is elastically slidably arranged on the rotating ring 42 and is slidably matched with the locking groove 41.

[0037] The outer side of the locking groove 41 is provided with a first clamping strip 411, a second clamping strip 412, and a third clamping strip 413. The first clamping strip 411 and the second clamping strip 412 are arranged in the same circular ring and are spaced apart from each other. The second clamping strip 412 and the third clamping strip 413 are arranged in the same axial direction and are spaced apart from each other. The third clamping strip 413 is spaced apart from the gun body 21 in the axial direction.

[0038] Specifically, one end of the third clamping strip 413 is provided with a driving inclined surface 414.

[0039] Further, the rotating ring 42 is provided with a protruding portion 421, and the protruding portion 421 is provided with an elastic member 44. The elastic member 44 includes a guide rod 441 fixedly connected to the side wall of the protruding portion 421. The locking block 43 is slidably sleeved on the guide rod 441. A driving spring 442 is sleeved on the guide rod 441. The two ends of the driving spring 442 are respectively abutted against the protruding portion 421 and the locking block 43.

[0040] Further, the outer wall of the locking block 43 is provided with a driving block 431 and a limiting block 432 in the axial direction. The driving block 431 and the limiting block 432 are spaced apart from each other. One end of the driving block 431 is provided with a passive inclined surface 433 which is matched with the driving inclined surface 414.

[0041] Further, the locking block 43 is elastically slidably arranged on the protruding portion 421. The side wall of the locking block 43 is slidably matched with the side wall of the protruding portion 421.

[0042] It should be noted that the locking relationship between the charging gun 2 and the vehicle charging port 2 in the present application and the locking relationship between the gun head 22 and the gun body 21 have common locking or unlocking states, and at the same time, the locking relationship between the charging gun 2 and the vehicle charging port 2 is accompanied by the control of the on-off of the current by the control system, that is, the current is turned on when it is locked, and the current is turned off after it is unlocked, so as to ensure the safety of the user during use, and at the same time, it forces the user to separate the gun head 22 and the gun body 21 after use, and stores the gun head 22 in the storage cabin, so as to ensure the safety of the gun head 22, and avoid falling dust or being damaged by accidental touch.

[0043] It should be further noted that a protrusion is arranged in the upper part of the vehicle charging port, so that the limiting block 432 is clamped inside the protrusion, so that the axial positioning between the entire charging gun 2 and the charging port is formed.

[0044] In specific use, for example, Figure 14 and Figure 15As shown, the left side of the figure is the locking state, the right side is the unlocking state, and the middle is the transition action. Specifically, from the right side of the figure to the left side, the locking action is as follows: when a user uses the charging gun 2, the user inserts the appropriate gun head 22 into the charging port of the vehicle, and then inserts the gun body 21 into the gun head 22. The connecting assembly 32 is rotated and displaced along the rotating groove 213 until the connecting assembly 32 axially fixes the gun head 22. During this process, the swivel ring 42 is synchronously rotated and drives the locking block 43 to slide out from between the second clamping strip 412 and the third clamping strip 413. When the locking block 43 is separated from the second clamping strip 412 and the third clamping strip 413, the locking block 43 is displaced outward and axially slides under the action of the elastic force of the driving spring 442. This causes the limiting block 432 to be axially displaced to the outside of the first clamping strip 411 and the second clamping strip 412. At the same time, the locking block 43 is axially limited between the passive slope 433 and the driving slope 414, which ensures that the locking block 43 does not escape from the locking groove 41. At this time, the connecting assembly 32 has not been displaced to the position for locking the gun head 22. It should be noted that, at this time, the axial position of the limiting block 432 should be inside the inner side of the protrusion inside the charging port. In the subsequent rotating process, when the connecting assembly 32 is rotated to the position for locking the gun head 22, the limiting block 432 is rotated to the protrusion inside the charging port and is clamped. At this time, the driving block 431 is rotated to the inside of the first clamping strip 411, which axially limits the entire locking block 43. At this time, the gun body 21, the gun head 22, and the charging port form a locking state. Conversely, when the charging gun 2 needs to be removed, the connecting assembly 32 is reversely operated, which synchronously reversely rotates and reversely axially displaces the locking block 43. It should be noted that, during this process, when the locking block 43 is displaced to the position where the driving block 431 is separated from the first clamping strip 411, the passive slope 433 and the driving slope 414 are engaged at this time. In the subsequent rotating process, the locking block 43 is axially displaced inward under the action of the engagement of the slopes, and the driving spring 442 is compressed. Until the driving block 431 and the limiting block 432 are respectively displaced to the inside of the second clamping strip 412 and the third clamping strip 413, the locking block 43 is positioned. At this time, the gun head 22 and the gun body 21 are unlocked, and the gun body 21 and the charging port are unlocked. The user winds the gun body 21 on the gun hanging disc 11, and removes the gun head 22 from the charging port and places it in the storage cabin.

[0045] In the related art, the new energy vehicle charging robot. Because the gun head 22 and the gun body 21 need to be inserted and removed every time for charging, the power supply contact 23 in the gun body 21 may be irreversibly deformed by abutting against the power contact 221 on different gun heads 22, which may cause the gun head 22 and the gun body 21 to be in poor contact (power supply relationship).

[0046] In some embodiments of the present application, as Figure 16As shown, the power supply contact 23 elastically slides in the power supply cavity 215, and the side of the power supply contact 23 away from the gun head 22 abuts against the conductive spring 231.

[0047] The other end of the conductive spring 231 is fixedly connected with the power supply part 232, and the power supply part 232 is electrically connected with the cable on the charging robot body 1.

[0048] Thus, when the gun head 22 is inserted into the gun body 21 during actual use, the power supply contact 23 is abutted against the electric contact 221, and the force will be displaced inward along the power supply cavity 215 and press the conductive spring 231, so that the electric contact 221 and the power supply contact 23 form an elastic abutting state, which can ensure the power supply effect and avoid irreversible deformation of the power supply contact 23. The design can ensure the stable power supply relationship between the gun head 22 and the gun body 21 and prolong the service life of the charging gun 2.

[0049] It should be noted that the specific model and specifications of the charging robot body 1, the gun hanging disc 11, the touch screen 14, the warning light 18, the conductive spring 231, the tension spring 323 and the driving spring 442 need to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in the art, and thus will not be described in detail.

[0050] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
