Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a liquid-cooled fast-charging charging pile. Background Art

[0002] A charging pile, also known as an electric vehicle charging station or electric vehicle power supply equipment, is a device that provides electrical energy to electric vehicles, enabling them to store enough electricity to support their operation.

[0015] 1. For the liquid-cooled fast-charging charging pile, when the cable is pulled and the charging pile body tilts forward or backward, the limit block, support rod, L rod, rocker arm, connecting rod, slide rail and slide can drive the counterweight block to move in the opposite direction of the tilt of the charging pile body.

[0016] 2. The liquid-cooled fast-charging charging pile can drive the clamping plate to clamp the cable through the sliding cooperation of the slide frame, the push rod, the bending rod, the sliding frame, the through groove, the guide rod, the slider and the positioning rod. At this time, the clamping plate can be used to fix the cable, so that when the cable is pulled, the tension at the connection between the cable and the charging pile body can be reduced, preventing the cable from being pulled and causing damage to the connection between the cable and the charging pile body; and the sliding cooperation of the slider with the guide rod and the inclined groove can drive the slide plate to gradually approach the cable. At this time, the telescopic spring and the top rod on the inner wall of the slide plate can be used to limit the height of the cable, so that the cable can be stably placed between the two sets of clamping plates, so that the clamping plates can better clamp the cable and give full play to the clamping effect of the clamping plates.

[0017] 3. The liquid-cooled fast-charging charging pile can push the limit rod through the sliding cooperation of the slide plate and the connecting rod, and then drive the limit rod to slide on the inner wall of the charging pile, and the sliding of the limit rod can release the limit on the top cover. When the limit rod releases the limit on the top cover, the top cover and the bottom cover can be driven to fit together under the elastic action of the return spring. At this time, the charging gun can be covered by the top cover and the bottom cover, thereby protecting the charging gun and preventing the charging pile body from tipping over and causing damage to the charging gun.

One end of the connecting spring 53 is fixedly installed on the side wall of the slide 52, and the other end of the connecting spring 53 is fixedly installed on the inner wall of the slide rail 51. The elasticity of the connecting spring 53 can drive the slide 52 to slide and reset on the inner wall of the slide rail 51. The vertical rod 54 A slide groove 55 is provided on the top, a rocker arm 57 is hinged on the outer wall of the charging pile body 1, one end of the connecting rod 58 is hinged on the outer wall of the rocker arm 57, and the other end of the connecting rod 58 is hinged on the outer wall of the slide 52. The rocker arm 57 rotates on the outer wall of the charging pile body 1 and cooperates with the connecting rod 58 to push the slide 52 so that the slide 52 will slide on the inner wall of the slide rail 51. The support rod 59 is fixedly installed on the outer wall of the charging pile body 1. The outer wall of the support rod 59 is slidably connected to the limit block 510. The inner wall of the cable 2 is attached to the inner wall of the limit block 510. When the cable 2 is pulled and causes the charging pile body 1 to move forward or backward When tilting backward, the cable 2 will push the limit block 510, causing the limit block 510 to slide on the outer wall of the support rod 59. The outer wall of the limit block 510 is fixedly installed with an L rod 511. When the limit block 510 slides, it will drive the L rod 511 to move synchronously. When the L rod 511 contacts the rocker arm 57 during the movement, it will squeeze the rocker arm 57, causing the rocker arm 57 to rotate on the outer wall of the charging pile body 1. The boss 512 is fixedly installed on the top of the charging pile body 1. When the cable 2 is pulled and causes the charging pile body 1 to tilt to the left or right, the charging pile body 1 will drive the boss 512 to tilt synchronously.

[0028] The inner wall of the slide 52 is slidably connected to a vertical rod 54, and a counterweight 56 is fixedly installed at the bottom of the vertical rod 54. The slide 52 slides on the inner wall of the slide rail 51, and at the same time, the center of gravity of the charging pile body 1 can be adjusted in conjunction with the vertical rod 54 and the counterweight 56 to prevent the charging pile body 1 from tipping forward or backward, thereby improving the stability of the charging pile body 1.

[0029] The inner wall of the boss 512 is hinged with a counterweight ball 513, and a T-shaped rod 514 is fixedly installed on the top of the counterweight ball 513. The outer wall of the T-shaped rod 514 fits into the inner wall of the slide 55. When the charging pile body 1 tilts to the left or right, the counterweight ball 513 on the inner wall of the boss 512 will rotate with the change of the center of gravity of the charging pile body 1. While the counterweight ball 513 rotates, it can cooperate with the T-shaped rod 514, the slide 55 and the vertical rod 54 to drive the counterweight block 56 to move in the opposite direction of the tilt direction of the charging pile body 1. At this time, the counterweight block 56 can be used to make the center of gravity of the charging pile body 1 deviate to the opposite direction of the tilt, thereby preventing the charging pile body 1 from tipping over to the left or right.

[0030] When this embodiment is working: when the cable 2 is pulled and causes the charging pile body 1 to tilt forward or backward, the cable 2 will push the limit block 510, so that the limit block 510 slides on the outer wall of the support rod 59. While the limit block 510 slides, it will drive the L rod 511 to move synchronously. When the L rod 511 contacts the rocker rod 57 during the movement, it will squeeze the rocker rod 57, so that the rocker rod 57 rotates on the outer wall of the charging pile body 1. While the rocker rod 57 rotates, it will push the connecting rod 58, so that the connecting rod 58 pushes the slide 52. At this time, the slide 52 will slide on the inner wall of the slide rail 51 and stretch the connecting spring 53. At the same time, the slide 52 will drive the vertical rod 54 to gradually move away from the charging pile body 1, so that the vertical rod 54 drives the counterweight block 56 to gradually move away from the charging pile body 1, thereby making the counterweight block 56 and the limit block 510 move in opposite directions. The movement of the counterweight block 56 can make the center of gravity of the charging pile body 1 tilted. When the charging pile body 1 is tilted to the left or right, the charging pile body 1 will drive the boss 512 to tilt synchronously. At this time, the counterweight ball 513 on the inner wall of the boss 512 will rotate with the change of the center of gravity of the charging pile body 1. At the same time, the counterweight ball 513 will drive the T-shaped rod 514 to rotate in the opposite direction of the tilting direction of the charging pile body 1. At this time, the T-shaped rod 514 will fit on the inner wall of the slide groove 55 and move and push the vertical rod 54, so that the vertical rod 54 slides on the inner wall of the slide 52. At the same time, the vertical rod 54 will drive the counterweight block 56 to move in the opposite direction of the tilting direction of the charging pile body 1. At this time, the counterweight block 56 can make the center of gravity of the charging pile body 1 deflected to the opposite direction of the tilt, thereby preventing the charging pile body 1 from tipping over to the left or right.

[0031] See also Figure 1-Figure 7On the basis of the above embodiment, another embodiment of the present invention further includes a clamping mechanism 6 and a protective mechanism 7. The clamping mechanism 6 includes a slider 61, a positioning rod 62, a limiting plate 63, a clamping plate 64, a positioning spring 65, a guide rod 66, a slide frame 67, a bent rod 68, a push rod 69, a through groove 610, a limiting spring 611, a slide plate 612, a chute 613, a push rod 614 and a telescopic spring 615. The slider 61 is slidably connected to the outer wall of the charging pile body 1, and the inner wall of the slider 61 is slidably connected to the positioning rod 62, and the positioning rod 62 passes through the slider 61. The positioning spring 6 One end of 5 is fixedly mounted on the outer wall of the limit plate 63, and the other end of the positioning spring 65 is fixedly mounted on the outer wall of the slider 61. During the sliding process of the slider 61 on the outer wall of the charging pile body 1, the positioning spring 65 and the limit plate 63 can drive the positioning rod 62 to move synchronously. The outer wall of the slider 61 is fixedly mounted with a guide rod 66, and the inner wall of the support rod 59 is slidably connected with a slide frame 67, and the slide frame 67 passes through the support rod 59. The top of the slide frame 67 is fixedly mounted with a bent rod 68, and the side wall of the slide 52 is fixedly mounted with a push rod 69. A through slot 610 is provided on the slide frame 67. The guide rod 6 The outer wall of 6 is fitted into the inner wall of the through groove 610. When the sliding frame 67 slides on the outer wall of the charging pile body 1, it will drive the through groove 610 to squeeze the guide rod 66, so that the guide rod 66 pushes the slider 61. The outer wall of the sliding frame 67 is fixedly installed with a limit spring 611. The end of the limit spring 611 away from the sliding frame 67 is fixedly installed on the top of the support rod 59. When the sliding frame 67 slides upward on the inner wall of the support rod 59, the limit spring 611 is stretched. The outer wall of the charging pile body 1 is slidably connected with a slide plate 612. The slide plate 612 is provided with an oblique groove 613. The guide rod 66 is away from the slider. One end of 61 is fitted into the inner wall of the inclined groove 613. When the slider 61 slides on the outer wall of the charging pile body 1, it will drive the guide rod 66 to fit into the inner wall of the inclined groove 613 and move. At this time, the guide rod 66 will squeeze the inclined groove 613, so that the slide plate 612 slides on the outer wall of the charging pile body 1. The side wall of the top rod 614 is fixedly installed with a telescopic spring 615. The end of the telescopic spring 615 away from the top rod 614 is fixedly installed on the inner wall of the slide plate 612. When the slide plate 612 slides on the outer wall of the charging pile body 1, it can cooperate with the telescopic spring 615 to drive the top rod 614 to move synchronously.

[0032] A limiting plate 63 is fixedly installed at one end of the positioning rod 62, and a clamping plate 64 is fixedly installed at the other end of the positioning rod 62. The positioning rod 62 can drive the clamping plate 64 to clamp the cable 2 through the sliding of the slider 61. Clamping the cable 2 by the clamping plate 64 can reduce the tension at the connection between the cable 2 and the charging pile body 1, preventing the cable 2 from being pulled and causing damage to the connection between the cable 2 and the charging pile body 1.

[0033] The inner wall of the slide plate 612 is slidably connected to a push rod 614, and the push rod 614 passes through the slide plate 612. By sliding the slide plate 612 on the outer wall of the charging pile body 1 and gradually approaching the cable 2, the push rod 614 can be driven to fit on the surface of the cable 2. At this time, the low push rod 614 can be used to limit the height of the cable 2, so that the cable 2 can be placed between the two sets of clamps 64, so that the clamps 64 can better clamp the cable 2.

[0034] The protective mechanism 7 includes a bottom cover 71, a top cover 72, a return spring 73, a limit rod 74 and a connecting rod 75. One end of the return spring 73 is fixedly mounted on the bottom of the top cover 72, and the other end of the return spring 73 is fixedly mounted on the inner wall of the charging pile body 1. When the limit rod 74 releases the limit on the top cover 72, the elasticity of the return spring 73 can drive the top cover 72 to slide downward on the outer wall of the charging pile body 1 and reset. The inner wall of the charging pile body 1 is slidably connected to the limit rod 74, and The limiting rod 74 passes through the charging pile body 1, and the top of the limiting rod 74 is attached to the bottom of the top cover 72. When the limiting rod 74 is completely separated from the bottom of the top cover 72, the limit on the top cover 72 will be released. The outer wall of the limiting rod 74 is hinged with a connecting rod 75, and the end of the connecting rod 75 away from the limiting rod 74 is hinged to the outer wall of the slide 612. When the slide 612 slides on the outer wall of the charging pile body 1, it can cooperate with the connecting rod 75 to push the limiting rod 74, so that the limiting rod 74 slides on the inner wall of the charging pile body 1.

[0035] The bottom cover 71 is fixedly mounted on the outer wall of the charging pile body 1, and the top cover 72 is slidably connected to the outer wall of the charging pile body 1. The top cover 72 slides downward on the outer wall of the charging pile body 1 and fits onto the top of the bottom cover 71. The top cover 72 cooperates with the bottom cover 71 to cover the charging gun 3, thereby protecting the charging gun 3 and preventing the charging pile body 1 from tipping over and causing damage to the charging gun 3.

[0036] When this embodiment is working: when the slide 52 drives the counterweight 56 to gradually move away from the charging pile body 1, the slide 52 will drive the push rod 69 to move synchronously. When the push rod 69 contacts the bent rod 68 during the movement, it will squeeze the bent rod 68, so that the bent rod 68 drives the slide frame 67 to slide upward on the inner wall of the support rod 59. At the same time, the bent rod 68 will stretch the limit spring 611, and the slide frame 67 will drive the through groove 610 to squeeze the guide rod 66 while sliding upward, so that the guide rod 66 pushes the slide block 61. At this time, the slide block 61 will slide on the outer wall of the charging pile body 1 and gradually approach the cable 2. When the slide block 61 moves, it will drive the positioning spring 65 to move synchronously. When the positioning spring 65 moves, it will drive the limit plate 63 to move synchronously. When the limit plate 63 moves, it will drive the positioning rod 62 to move synchronously. At this time, the positioning rod 62 will drive the splint 64 to gradually approach the cable 2. At this time, the two sets of sliders 61 can be used to make the positioning rod 62 drive the clamping plate 64 to clamp the two sides of the cable 2. Clamping the cable 2 by the clamping plate 64 can reduce the tension at the connection between the cable 2 and the charging pile body 1. The slider 61 will drive the guide rod 66 to move in contact with the inner wall of the inclined groove 613 in the process of gradually approaching the cable 2. At this time, the guide rod 66 will squeeze the inclined groove 613, so that the slide plate 612 slides on the outer wall of the charging pile body 1 and gradually approaches the cable 2. While the slide plate 612 slides, it will drive the telescopic spring 615 to move synchronously. While the telescopic spring 615 moves, it will drive the top rod 614 to gradually approach the cable 2, so that the top rod 614 can be fitted on the surface of the cable 2. At this time, the low top rod 614 can be used to limit the height of the cable 2, so that the cable 2 can be placed between the two sets of clamping plates 64, so that the clamping plate 64 can better clamp the cable 2.

[0037] As the slide plate 612 slides on the outer wall of the charging pile body 1 and gradually approaches the cable 2, it will push the connecting rod 75, causing the connecting rod 75 to push the limiting rod 74. At this time, the limiting rod 74 will slide on the inner wall of the charging pile body 1 and gradually slide out of the charging pile body 1. In this process, the limiting rod 74 will gradually separate from the bottom of the top cover 72. When the limiting rod 74 is completely separated from the bottom of the top cover 72, the limit on the top cover 72 will be released. At this time, the return spring 73 will pull the top cover 72 downward, causing the top cover 72 to slide downward on the outer wall of the charging pile body 1, and then the top cover 72 can be fitted on the top of the bottom cover 71. At this time, the top cover 72 can cooperate with the bottom cover 71 to cover the charging gun 3 to prevent the charging pile body 1 from tipping over and causing damage to the charging gun 3.
