Description

Technical Field

[0001] The present invention relates to the technical field of materials science and engineering, and specifically to a charging gun sealing placement rack for new energy charging piles and its charging method. Background Technique

[0002] With the rapid popularization of electric vehicles and other new energy vehicles, the demand for charging facilities is also increasing day by day. The charging pile is one of the key devices for electric vehicle charging, and the charging gun is a component in the charging pile responsible for connecting to the electric vehicle and transmitting electric energy. This sealing placement rack is usually made of strong materials, has excellent sealing performance and corrosion resistance. It provides a stable storage position for the charging gun and adopts a sealing design to prevent dust, moisture and other harmful substances from entering the interior of the placement rack. Moreover, the new energy charging gun is a high-value device, so it needs to be protected from damage. The sealing placement rack can prevent the charging gun from being accidentally collided, dropped or damaged by other external forces.

[0003] During the use of current devices, there are still many inconveniences;

[0004] The specific defects are as follows:

[0005] First, the existing charging guns are often clamped inside the placement rack so that users can conveniently hold the charging gun for charging operations. However, the environment where the charging pile equipment is located is often affected by external vibrations, such as heavy traffic flow, rough roads, etc. These vibrations will be transmitted to the placement rack, affecting the stability of the charging gun. Moreover, the charging pile equipment is often placed outdoors and is easily affected by the wind. Strong winds will exert lateral or up-and-down forces on the placement rack, causing the charging gun to lose balance. Since the placement rack is located outdoors, the placement rack will also be collided by motor vehicles. For example, when parking, the vehicle accidentally hits the charging pile equipment. Such a collision will cause the charging gun to fall or tilt from the placement rack. Since the charging gun is not placed stably, the charging gun will break away from the placement rack, resulting in the charging gun being unable to be used or damaged.

[0006] Second, the charging gun connection port is usually exposed. When the charging gun is in use, the placement rack connection port is often exposed to the outside world, and the placement rack connection port is not effectively sealed. Rainwater, moisture or other liquids may enter the interface. The entry of moisture will cause water accumulation inside the placement rack connection port. When the charging gun enters the placement rack connection port, the charging gun encounters water, resulting in poor contact, short circuit or damage to electrical components of the charging gun. Moreover, the placement rack connection port is prone to adsorbing dust, particulate matter or other sundries during use. These sundries will accumulate in the interface, resulting in problems such as poor electrical connection or damaged contacts during the charging process of the charging gun.

[0007] Therefore, the present invention provides a charging gun sealed placement rack for a new energy charging pile and its charging method to make up for and improve the deficiencies of the prior art. Summary of the Invention

The limiting mechanism effectively restricts the movement range of the slot charging gun, avoiding the slot charging gun from falling off the inside of the placement rack due to accidental collisions from the outside and harsh environments. This limiting design can ensure that the slot charging gun is stably fixed inside the placement rack, reducing potential safety hazards and ensuring the safety of the charging process.

[0028] 2. By using the charging box body in combination with the closing mechanism, as the rotation angle of the rotating plate increases, the side length of the equilateral hexagon channel formed by multiple closing plates decreases, thereby closing the access port that was originally exposed to the outside world, solving the problem that the access port of the placement rack is exposed to the outside world and is prone to water accumulation and dust collection. Sealing the access port of the placement rack can effectively prevent impurities such as moisture and dust from entering the access port of the placement rack, thereby protecting the internal components of the card slot charging gun from damage. This helps to extend the lifespan of the card slot charging gun and reduce the costs of maintenance and replacement. Moreover, sealing the access port of the placement rack can prevent external substances from entering the access port of the card slot charging gun, reducing the occurrence of short circuits, electric leakage, and other safety problems of the card slot charging gun caused by the influence of external impurities.

[0029] 3. By using the limiting mechanism in combination with the closing mechanism, when the card slot charging gun of the charging pile is not in use, the access port of the sealed placement rack is closed through the switch of the limiting mechanism, which can effectively prevent the waste of energy, avoid continuous power supply of the charging pile when the card slot charging gun is not inserted, reduce energy consumption, and controlling the state of the access port of the sealed placement rack through the switch of the limiting mechanism can make the operation more convenient. The operator only needs to control through the switch to achieve the opening and closing of the access port without complex operation steps, which can improve the operation efficiency and reduce the burden on the operator.

The surface of the limiting block 413 away from the support rod 1 is set as an inclined surface.

[0047] The effects achieved by this embodiment are as follows: The existing card slot charging gun 2 is often clamped inside the placement rack, so that users can conveniently hold the card slot charging gun 2 for charging operations. However, the environment where the charging pile equipment is located is often affected by external vibrations. For example, due to large traffic flow, rough roads and other reasons, these vibrations will be transmitted to the placement rack, affecting the stability of the card slot charging gun 2. By pushing the adjusting support rod 411 to control the limiting state of the charging box body 3 for the card slot charging gun 2, the problem that the card slot charging gun 2 is prone to looseness due to external influences inside the placement rack is solved. The limiting mechanism 4 effectively limits the moving range of the card slot charging gun 2, avoiding the card slot charging gun 2 from falling off the placement rack due to accidental external collisions and harsh environments. This limiting design can ensure that the card slot charging gun 2 is stably fixed inside the placement rack, reducing potential safety hazards.

[0048] The closing mechanism 5 includes a top side plate 511 which is slidably connected to the inside of the charging box body 3.

A closing plate 516 is slidably connected to the surface of the rotating circular plate 514.

A fixed side plate 515 is fixedly connected to the inside of the charging box body 3. An adjusting groove is formed on the surface of the fixed side plate 515. A first abutting shaft 517 is slidably connected to the surface of the closing plate 516, and the first abutting shaft 517 is slidably connected to the inside of the adjusting groove on the surface of the fixed side plate 515. The card shaft groove on the surface of the rotating circular plate 514 is a regular hexagon with equal side lengths. A plurality of first abutting shafts 517 are provided, and the plurality of first abutting shafts 517 are located at the centers of each side of the closing plate 516. A plurality of fixed side plates 515 are provided, and the inclination angles of the plurality of fixed side plates 515 on the inner wall of the charging box body 3 are sixty degrees. The side walls of the plurality of adjacent closing plates 516 are in contact with each other.

[0049] The effects achieved by this embodiment are as follows: The connection port of the card slot charging gun 2 is usually exposed. When the card slot charging gun 2 is in use, the access port of the placement rack is often exposed to the outside. The access port of the placement rack is not effectively sealed, and rainwater, moisture or other liquids may enter the interface. The entry of moisture will cause water accumulation inside the access port of the placement rack. When the card slot charging gun 2 enters the access port of the placement rack, the card slot charging gun 2 encounters water, resulting in poor contact, short circuit or damage to electrical components of the card slot charging gun 2. By increasing the rotation angle of the rotating circular plate 514, the side length of the equilateral hexagon channel formed by the plurality of closing plates 516 decreases, thereby closing the access port that was originally exposed to the outside, solving the problem that the access port of the placement rack is exposed to the outside and is prone to water accumulation and dust collection. Sealing the access port of the placement rack can effectively prevent impurities such as moisture and dust from entering the access port of the placement rack, thereby protecting the internal components of the card slot charging gun 2 from damage. This helps to extend the service life of the card slot charging gun 2 and reduce the costs of maintenance and replacement.

[0050] A charging method includes the following steps:

[0051] S1. Charging gun start step: The user removes the charging gun from the sealed placement rack by releasing the limit of the sealed placement rack on the charging gun, inserts it into the interior of the charging box body 3, and firmly fixes the charging gun inside the charging pile through the limiting mechanism 4;

[0052] S2. Placement rack sealing step: The charging gun is removed from the interior of the charging box body 3, and the sealed placement rack seals the access port of the charging box body 3 under the control of the closing mechanism 5;

[0053] S3. Charging gun completion step: The user places the charging gun back into the interior of the sealed placement rack, and the sealed placement rack limits the charging gun.

[0054] The following is the entire working process and working principle of the above embodiment:

[0055] Initial state: The central spring 4111 is in an un-stretched state, the side spring 416 is in an un-compressed state, the limit block 413 is located inside the access port of the charging box body 3, the slot charging gun 2 is located inside the access port of the charging box body 3, the access port inside the charging box body 3 is in an open state, the force-receiving spring 512 is in a compressed state, and the first abutting shaft 517 is located at one end of the fixed side plate 515 away from the slot charging gun 2.

[0056] During operation: Manually push the adjusting rod 411 to slide downward. When the adjusting rod 411 slides downward, the access opening that was originally in a closed state is opened. Since the adjusting rod 411 is fixedly connected to the power top plate 419, the downward sliding of the adjusting rod 411 drives the power top plate 419 to slide downward. Since the side pressure plate 418 is fixedly connected to the power top plate 419, the side spring 416 is compressed under the push of the power top plate 419, and the adjusting side frame 415 is pushed downward by the power top plate 419. Since the guide shaft 417 is fixedly connected to the adjusting side frame 415, the guide shaft 417 slides inside the adjusting inner frame 412 under the push of the adjusting side frame 415, providing guidance for the sliding direction of the side pressure plate 418 and preventing the adjusting side frame 415 from sliding off. As the adjusting side frame 415 slides downward, since one end of the rotating inner rod 4110 away from the central support block 414 is rotatably connected to the inside of the adjusting side frame 415, the adjusting side frame 415 slides downward under the push of the power top plate 419, and the rotating inner rod 4110 rotates inside the adjusting inner frame 412 towards the adjusting side frame 415. Since the rotating inner rod 4110 is rotatably connected to the inside of the central support block 414, the rotation of the rotating inner rod 4110 pushes the central support block 414 to slide upward, and the central spring 4111 is compressed under the push of the central support block 414. And the limiting block 413 is driven by the central support block 414 to disengage from the inside of the access opening of the charging box body 3 and fit against the inner wall of the access opening. When the slot charging gun 2 enters the inside of the access opening of the charging box body 3, by removing the manual thrust on the adjusting rod 411, the power top plate 419 loses the pulling force of the adjusting rod 411, and the central spring 4111 resumes its original state, thereby pushing the limiting block 413 into the limiting groove on the surface of the slot charging gun 2 through the rotating inner rod 4110, thus fixing the slot charging gun 2 placed in the access opening of the charging box body 3;

[0057] By pushing the adjusting rod 411 to control the limiting state of the charging box body 3 for the slot charging gun 2, the problem that the slot charging gun 2 is prone to looseness under the influence of the outside world inside the placement rack is solved. The limiting mechanism 4 effectively restricts the moving range of the slot charging gun 2, preventing the slot charging gun 2 from falling off the placement rack due to accidental collisions from the outside world and the influence of harsh environments. This limiting design can ensure that the slot charging gun 2 is stably fixed inside the placement rack, reducing safety hazards and ensuring the safety of the charging process. And by controlling the working state of the limiting mechanism 4 through the adjusting rod 411, the user cannot move the slot charging gun 2 when not charging, which can reduce the occurrence of misuse, avoid unnecessary operations on the slot charging gun 2, and reduce the damage risk of the slot charging gun 2.

[0058] Further, when the slot charging gun 2 is separated from the internal access port of the charging box body 3, when the central spring 4111 loses the thrust given by the slot charging gun 2 to the limit block 413 and is restored, the power top plate 419 is pulled to drive the adjusting rod 411 to slide downward. The downward sliding of the adjusting rod 411 drives the top side plate 511 fixedly connected to the adjusting rod 411 to slide downward. The downward sliding of the top side plate 511 pushes the sliding rod 513 to slide downward through the force receiving spring 512. Since the tooth blocks on the surface of the sliding rod 513 are engaged with the tooth blocks on the surface of the rotating circular plate 514, the downward sliding of the sliding rod 513 drives the rotating circular plate 514 to rotate. The rotating circular plate 514 rotates, and the card shaft groove on the surface of the rotating circular plate 514 is an equilateral hexagon. Since the second abutting shaft 518 at the bottom of the closing plate 516 extends into the card shaft groove on the surface of the rotating circular plate 514, when the rotating circular plate 514 rotates, the closing plate 516 slides driven by the second abutting shaft 518. Since the first abutting shaft 517 slides inside the fixed side plate 515 and the first abutting shaft 517 is fixedly connected to the closing plate 516, and since the adjusting groove inside the fixed side plate 515 is inclined, the closing plate 516 slides in the card shaft groove on the surface of the rotating circular plate 514 and slides obliquely under the restriction of the fixed side plate 515 on the first abutting shaft 517. Each closing plate 516 sliding on the surface of the rotating circular plate 514 slides in contact with the surface of the adjacent closing plate 516;

[0059] During the oblique sliding process of the adjacent closing plates 516, as the degree of the closing plate 516 sliding on the surface of the adjacent closing plate 516 decreases, a channel in the shape of an equilateral hexagon is formed inside the multiple closing plates 516. And as the rotation angle of the rotating circular plate 514 increases, the side length of the equilateral hexagon channel formed inside the multiple closing plates 516 decreases, thereby closing the access port that was originally exposed to the outside, solving the problem that the access port of the placement rack is exposed to the outside and is prone to water accumulation and dust collection. Sealing the access port of the placement rack can effectively prevent impurities such as moisture and dust from entering the access port of the placement rack, thereby protecting the internal components of the slot charging gun 2 from damage. This helps to extend the service life of the slot charging gun 2 and reduce the costs of maintenance and replacement. And sealing the access port of the placement rack can prevent external substances from entering the access port of the slot charging gun 2, reducing the occurrence of short circuits, electric leakage and other safety problems of the slot charging gun 2 caused by the influence of external impurities.

[0060] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
