[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Please see Figures 1-10As shown, the present invention is a charging gun with an anti-detachment structure, including a charging head 3 with a wire 2. The charging head 3 is inserted into the charging port of a new energy vehicle for charging. A storage box 1 is installed through the wire 2. The storage box 1 serves to store excess wire. Both the storage box 1 and the lifting plate 61 have movable grooves for the movement of the wire 2. A sliding roller 9 is rotatably installed on the inner wall of the movable groove on the storage box 1. A dustproof plate 7 is rotatably installed on the top surface of the storage box 1. An anti-detachment component 4 is provided on the charging head 3.

[0037] The anti-detachment component 4 includes a retractable support plate 41 rotatably mounted on the bottom surface of the charging head 3. The support plate 41 is mounted and supported on the charging port of the new energy vehicle. Multiple first limiting grooves 42 are provided on the side of the support plate 41 near the sliding groove 45. The sliding groove 45 is also provided on the side of the charging head 3 near the support plate 41, facilitating adjustment of the support position of the support rod 46 and allowing for adjustment of the charging head 3 as needed. The sliding groove 45 serves to house the support rod 46. On both sides of the sliding groove 45 are oblong through holes 47 with second limiting grooves 48. The second limiting grooves 48 serve to limit and stabilize the limiting rod 49, which slides within the oblong through holes 47. The support rod 46 for supporting the charging head 3 is slidably mounted within the sliding groove 45. The support plate 41 is equipped with… The support rod 46 serves to support and hold the charging head 3, resisting the pulling force of the cable 2 on the charging head 3. A second spring 411 is fixedly installed on the side of the support rod 46 near the slide groove 45. The second spring 411 drives the support rod 46 to elastically return to its original position. Limiting plates 43 with handles 419 are rotatably installed on both sides of the charging head 3. The handles 419 facilitate the squeezing of the limiting plates 43 out of the mounting groove, making it easier to unfold the support plate 41 to support the charging head 3. The limiting plates 43 lock and limit the support plate 41 that has retracted onto the charging head 3. The limiting plates 43 are used to limit the support plate 41 on the charging head 3. An extension unit for auxiliary support of the cable 2 is provided on the side of the storage box 1 near the charging head 3.

[0038] The extension unit includes a rectangular through-hole 412 with a storage box 1 near the charging head 3. A bidirectional screw 413 is rotatably installed inside the rectangular through-hole 412. The bidirectional screw 413 drives the moving block 414 to slide within the rectangular through-hole 412, facilitating the rotation plate 415 to lift the top plate 416. The top plate 416 then pulls the telescopic plate 417, allowing the telescopic plate 417 to extend and support the power cord 2. This reduces the pulling force of the power cord 2 on the charging head 3 and also serves as an auxiliary support to prevent the plate 41 from falling off. Functionally, a movable block 414 is threaded through the bidirectional screw 413 near both ends. A rotating plate 415 is rotatably mounted on the side of the movable block 414 near the charging head 3. A top plate 416 is rotatably mounted between the two rotating plates 415. A telescopic plate 417 is fixedly mounted between the top plate 416 and the storage box 1. A first gear 418 is rotatably mounted on one side of the storage box 1. The rotating shaft of the first gear 418 slides through the rectangular through hole 412 and is fixedly mounted on the bidirectional screw 413.

[0039] A limiting rod 49 is fixedly installed at one end of the support rod 46 near the second spring 411. The limiting rod 49 is slidably installed in the oblong through hole 47. The limiting rod 49 serves to limit and stabilize the support rod 46, making it easier for the support rod 46 to drive the limiting rod 49 to slide in the oblong through hole 47. A sliding plate 410 is fixedly installed at one end of the second spring 411 near the slide groove 45. The sliding plate 410 slides in the slide groove 45. The second spring 411 serves to elastically reset the support rod 46 and retract it into the slide groove 45. The other end of the support rod 46 is engaged in the first limiting groove 42, which facilitates the support plate 41 and the charging head 3, and minimizes the possibility of the charging head 3 falling off.

[0040] The charging head 3 has mounting slots on both sides. The limiting plate 43 is rotatably installed in the mounting slot. A first spring 44 is fixedly installed between the limiting plate 43 and the mounting slot. The first spring 44 plays the role of elastically resetting the limiting plate 43 and the mounting slot. An arc plate with a protective pad is fixedly installed at the end of the support plate 41 away from the charging head 3. The protective pad and dustproof plate 7 play the role of protecting the car charging port, facilitating the support of the charging head 3, improving the stability of the device, and minimizing the possibility of the charging head 3 falling off.

[0041] Example 2

[0042] Please see Figure 1 and Figure 5As shown, based on Embodiment 1, the charging head 3 is provided with a locking component 8. The locking component 8 facilitates the locking and installation of the charging head 3 onto the charging port of the new energy vehicle. The locking component 8 includes a shrinkage groove 82 on the side of the charging head 3 away from the power cord 2. A locking plate 83 with a balance bar 84 is slidably installed within the shrinkage groove 82. The balance bar 84 slides through the locking plate 83 and is fixedly installed at both ends on the inner wall of the shrinkage groove 82, thus balancing and stabilizing the locking plate 83. The side of the locking plate 83 closest to the handle 419 is fixed... A button lever 81 is fixedly installed, and the other end of the button lever 81 slides through the shrink groove 82 to facilitate the compression of the locking plate 83. A shaped spring piece 85 is fixedly installed on the side of the locking plate 83 away from the button lever 81. The other end of the shaped spring piece 85 is fixedly installed on the inner wall of the shrink groove 82. The elastic force of the shaped spring piece 85 facilitates the locking plate 83 to elastically lock into the charging port. The locking plate 83 facilitates the further locking and installation of the charging head 3, and minimizes the possibility of the charging head 3 falling off the charging port, further improving the anti-detachment ability of the device and helping to improve the locking stability of the device.

[0043] Example 3

[0044] Please see Figure 9 and Figure 10 As shown, based on Embodiment 1 and Embodiment 2, a winding assembly 5 is provided inside the storage box 1. The winding assembly 5 includes two mounting plates 51 fixedly installed inside the storage box 1. A winding roller 52 and a clamping roller 53 are rotatably installed between the two mounting plates 51. The winding roller 52, in conjunction with the clamping roller 53, under the action of the motor 54, serves to send the wire 2 out or retract it into the storage box 1. A cleaning brush 55 is fixedly installed on the corresponding side of the winding roller 52. The cleaning brush 55 serves to clean the dust on the wire 2. The motor 54 is fixedly installed on the side of the winding roller 52 away from the cleaning brush 55. A second gear 510 is rotatably installed on the side of the storage box 1 near the first gear 418. The second gear 510 and the first gear 418 are meshed and connected to each other, which facilitates the synchronous rotation of the bidirectional screw 413, facilitates the unfolding of the telescopic plate 417, and facilitates the support of the wire 2.

[0045] The two mounting plates 51 have grooves 56 on their corresponding sides. A slider 57 is slidably mounted in each groove 56. The slider 57 facilitates the clamping roller 53 to squeeze the wire 2 between the take-up roller 52 and the clamping roller 53 under the elastic action of the third spring 59, increasing the friction between the take-up roller 52 and the charging head 3, thus facilitating the feeding or retraction of the wire 2 by the take-up roller 52. A guide rod 58 is slidably mounted through the slider 57, guiding and stabilizing it. A third spring 59 is fixedly mounted on the side of the slider 57 closest to the take-up roller 52. The third spring 59 is a tension spring, facilitating the movement of the clamping roller 53 towards the take-up roller 52 via the slider 57. The output end of the motor 54 slidably passes through the mounting plate 51 and is fixedly mounted on the take-up roller 52, allowing the motor 54 to drive the take-up roller 52 to rotate between the mounting plates 51. The rotating shaft of the second gear 510 slidably passes through the storage box 1 and the other mounting plate 51. The third spring 59 is fixedly installed on the take-up roller 52. The other end of the third spring 59 is fixedly installed on the inner wall of the groove 56. Both ends of the guide rod 58 are fixedly installed on the inner wall of the groove 56. The third spring 59 is nested on the outer surface of the guide rod 58. The clamping roller 53 is squeezed to make the clamping roller 53 drive the slider 57 to slide on the guide rod 58 and stretch the third spring 59, so that the third spring 59 is in a stretched state. The elastic restoring force of the third spring 59 drives the clamping roller 53 to squeeze the wire 2 onto the take-up roller 52, which facilitates the installation of the wire 2. The clamping roller 53 is rotatably installed on the slider 57, which facilitates the operation of clamping the wire 2 and facilitates the storage operation of the storage box 1 for the wire 2. It avoids the excess wire 2 being dragged on the ground, which is easy to damage the wire 2. It facilitates the storage operation, facilitates the clamping and winding of the wire 2, and drives the telescopic plate 417 to unfold and support the wire 2, which is beneficial to improving the clamping capacity of the device and improving the storage capacity of the device.

[0046] Example 4

[0047] Please see Figure 9 and Figure 10As shown, based on Embodiments 1, 2, and 3, a clamping assembly 6 is provided inside the storage box 1. The clamping assembly 6 includes a lifting plate 61 with an electric telescopic rod 62 slidably mounted on it. The electric telescopic rod 62 is raised and lowered, facilitating the lifting plate 61 to retract the charging head 3 into the storage box 1. The dustproof plate 7 on the cover serves as a dustproof measure. Two fixing plates 63 and a vertical plate 66 are fixedly installed on the side of the lifting plate 61 away from the electric telescopic rod 62. A placement groove 67 is opened at the end of the vertical plate 66 away from the lifting plate 61, and the button rod 81 is easily engaged and installed into the placement groove 67. The fixing plates 63 are located away from the lifting plate 61. An elastic plate 64 is fixedly installed at one end, which guides the charging head 3 to be inserted into the lifting plate 61. A fourth spring 65 is fixedly installed between the elastic plate 64 and the fixed plate 63. The elastic plate 64 and the fourth spring 65 work together to elastically clamp the charging head 3. A baffle 68 for hanging the handle 419 is rotatably installed on the placement slot 67. The baffle 68 rotates horizontally to facilitate hanging the handle 419, facilitating the storage of the charging head 3, and making it convenient for guiding and clamping the charging head 3. This also facilitates dustproof storage and improves the guiding and clamping ability of the device, as well as its dustproof storage capability and user experience.

[0048] The working principle of this invention is as follows: When using the device, first open the dustproof plate 7, then start the electric telescopic rod 62 to push the lifting plate 61 out of the storage box 1. Then rotate the baffle 68 to a vertical position, then take the handle 419 to drive the button rod 81 out of the placement slot 67. Then start the motor 54 to drive the take-up roller 52 to rotate. Under the elastic clamping of the clamping roller 53 and the third spring 59, the wire 2 in the storage box 1 is transported out, while the wire 2 rolls on the sliding roller 9. At the same time, the take-up roller 52 drives the second gear 510. The rotation causes the second gear 510 to drive the first gear 418 to rotate, which in turn drives the double-ended screw 413 to rotate. Simultaneously, the double-ended screw 413 causes the moving block 414 to slide relative to the rectangular through hole 412. The moving block 414 also drives the rotating plate 415 to push the top plate 416 out of the rectangular through hole 412, causing the top plate 416 to unfold the telescopic plate 417, which supports the wire 2 transported from the storage box 1. Simultaneously, squeezing the handle 419 causes the handle 419 to drive the limiting plate 43 to rotate in the mounting slot, while simultaneously stretching the limiting plate 43. The first spring 44 is compressed, which simultaneously reduces the restriction of the limiting plate 43 on the support plate 41, causing the support plate 41 to rotate out and engage with the edge of the charging port. Simultaneously, the support rod 46 rotates and slides out of the slide groove 45. Then, the support rod 46 is moved, causing the limiting rod 49 to slide within the oblong through hole 47. Simultaneously, the support rod 46, via the second spring 411, causes the sliding plate 410 to slide within the slide groove 45. After adjusting the support position of the support rod 46, it is inserted into the first limiting groove 42, and the charging head 3 is released. The support rod 46 is pressed to compress the second spring 411, causing the limiting rod 49 to be inserted into the second limiting groove 48. Then the support plate 41 is activated, causing the support plate 41 to bring the charging head 3 flush with the charging port. At the same time, the button rod 81 is pressed, causing the button rod 81 to compress the locking plate 83. The locking plate 83 slides in the shrink groove 82, compressing the irregular spring piece 85, so that the locking plate 83 is in a compressed state. At the same time, the locking plate 83 slides on the balance rod 84. Then the charging head 3 is inserted into the charging port. The button rod 81 is released, and the elastic restoring ability of the irregular spring piece 85 causes the locking plate 83 to lock into the charging port.

[0049] After charging is complete, repeat the above operation in reverse: retract the power cord 2 into the storage box 1, then move the charging head 3 and install it on the lifting plate 61. At the same time, make the charging head 3 press the elastic plate 64, which in turn presses the fourth spring 65, so that the fourth spring 65 and the elastic plate 64 are in a compressed state. Simultaneously, insert the button rod 81 into the placement slot 67. Then rotate the baffle 68 to block the handle 419 laterally to stabilize the charging head 3. Then retract the electric telescopic rod 62, which will drive the lifting plate 61 and the fixing plate 63 to retract into the storage box 1. Finally, cover it with the dustproof plate 7.

[0050] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
