Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a double-pile four-gun simultaneous charging pile for new energy heavy trucks. Background Art

[0002] New energy heavy truck charging piles are devices designed to meet the high-power charging requirements of heavy electric vehicles (such as electric trucks). As the logistics transportation industry develops towards a more environmentally friendly direction, the application of electric heavy trucks is becoming increasingly widespread, and the demand for efficient and reliable charging infrastructure has also increased accordingly.

[0003] After retrieval, a Chinese patent with the publication number CN117863927A discloses a new energy charging pile that is easy to use. The charging pile is covered by a protective shell to form a protection, and then the bearing seat is connected to the protective shell. When rotation is required, the touch snap ring engaged in the rotating assembly drives the turntable together with the lower rotating shaft column to rotate on the rotating table, thereby indirectly driving the charging pile on the protective shell to complete the orientation conversion. Thus, in the case where the new energy vehicle parking space is occupied, rotation is completed to provide operating space and convenience for users of reverse new energy vehicles. However, when this solution is actually used, there are still the following deficiencies:

[0004] When charging new energy heavy trucks, since these vehicles are usually equipped with large-capacity battery packs, the single-gun charging method not only takes a long time but also is difficult to meet the requirements of rapid turnover. Therefore, a double-gun simultaneous charging method is often required to significantly improve the charging efficiency. However, the existing charging gun configuration requires users to take out and plug in each charging gun one by one to complete the connection, which is particularly inconvenient for new energy heavy trucks. Especially in the face of logistics application scenarios with frequent in and out and time sensitivity, this one-by-one plugging and unplugging operation method greatly increases the burden on users and may lead to a decrease in the utilization rate of the charging station.

[0005] Therefore, the present application provides a double-pile four-gun simultaneous charging pile for new energy heavy trucks to meet the requirements of rapid double-gun simultaneous charging for new energy heavy trucks. Summary of the Invention

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. For the double-pile four-gun simultaneous charging charging pile for new energy heavy trucks, by setting the connection assembly, the baffle is controlled by the electric push rod to change from the vertical state to the inclined state, thereby unlocking the connection sleeve, and two charging guns can be directly pulled out at one time for double-gun simultaneous charging, avoiding the cumbersome steps of plugging and unplugging one by one. This design greatly improves the operation convenience and efficiency. At the same time, during the process of pulling out the charging gun, the contact between the connection sleeve and the inclined baffle causes the charging gun to shake slightly, which helps to shake off water droplets or other impurities attached to it, ensuring the cleanliness and reliability of the charging gun and enhancing the safety of use.

[0020] 2. For the double-pile four-gun simultaneous charging charging pile for new energy heavy trucks, by setting the connection sleeve and the separation screw, when the distances between the two charging ports of the new energy heavy truck are different, the position of the separation screw can be adjusted by rotating the threaded sleeve to change the distance between the two charging guns to meet the requirements of different vehicle models. This characteristic significantly improves the versatility and flexibility of the charging pile, enabling it to serve more types of vehicles.

[0021] 3. The double-pile four-gun simultaneous charging pile for new energy heavy trucks, by setting a protection component, if the charging pile is about to collide, it will trigger the action of the pneumatic telescopic rod through the pressure plate, release the limit on the charging pile body and make it slide along the guide rod, thus realizing automatic avoidance. This not only reduces the risk of physical damage but also ensures the safe operation of the charging pile. At the same time, during the sliding process of the charging pile body, the spring telescopic rod drives the anti-collision plate to slide upward along the support rod, and pulls out multiple anti-collision plates through the connecting chain to form a protection barrier, further dispersing and absorbing the impact force and reducing the damage to the main structure of the charging pile.

[0022] 4. The double-pile four-gun simultaneous charging pile for new energy heavy trucks, by setting a warning component, when the charging pile body triggers the avoidance slide, the connecting plate presses the limit telescopic rod to release the limit on the warning rod. Under the action of gravity, the warning rod rotates and emits a warning signal to the driver through the reflective warning plate, using visual stimulation to timely remind the driver to pay attention to the charging pile ahead, prevent potential collision accidents, and improve the overall safety factor.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0038] like Figures 1 to 10As shown, a dual-pile four-gun charging pile for new energy heavy trucks includes a base 1 and a charging pile body 2 arranged inside the base 1, two groups of charging guns 3 are arranged on the side of the charging pile body 2, and connecting components are arranged between the two groups of charging guns 3, and a protective component is arranged on the top surface of the base 1;

[0039] The connection assembly includes a connection sleeve 41 fixedly mounted on the outer wall of one charging gun 3, a separation screw 42 fixedly mounted on the outer wall of the other charging gun 3 of the two charging guns 3, a threaded sleeve 43 rotatably mounted on the end of the connection sleeve 41, and the threaded sleeve 43 is screwed with the separation screw 42, and a limit frame 44 is fixedly mounted on the side of the charging pile body 2 at a position between the two charging guns 3, and the inner bottom surface and the inner top surface of the limit frame 44 are both provided with slots 45, and the inner sides of the two slots 45 are both provided with limit structures;

[0040] The limiting structure includes a plurality of baffles 46 rotatably mounted on the inner wall of the slot 45 through a rotating shaft, a transmission disk 47 is fixedly mounted on the ends of the plurality of baffles 46, a connecting rod 48 is rotatably mounted at the side edges of the plurality of transmission disks 47, an electric push rod 49 is hingedly connected to the inner wall of the slot 45, and a telescopic end of the electric push rod 49 is rotatably connected to the side of one of the plurality of transmission disks 47, and two opposing baffles 46 in the plurality of baffles 46 are provided with a clearance groove 410 corresponding to the connecting sleeve 41 at one end thereof that is close to each other;

[0041] When the user needs to charge the new energy heavy truck, he can directly charge two guns at the same time. Specifically, in the initial state, several baffles 46 are in a vertical state, and the connecting sleeve 41 and the separation screw 42 connect the two charging guns 3, and the connecting sleeve 41 is located at the end inside the limit frame 44. The two baffles 46 at the end fix the connecting sleeve 41 through the give way groove 410 thereon, and further lock the two charging guns 3 to avoid damage caused by random plugging and unplugging. When the user needs to use it, the charging pile body 2 can be activated and used. When the charging pile body 2 is activated, the electric push rod 49 can be extended. Since the fixed end of the electric push rod 49 is hinged to the inner wall of the slot 45, and the telescopic end is rotatably connected to the side of the transmission disk 47, the electric push rod 49 can drive a transmission disk 47 at the end to rotate when it is extended, and through the connecting rod 48, several transmission disks 47 are rotated synchronously, thereby turning the baffle 46 on the transmission disk 47 from a vertical state. By rotating the connecting sleeve 41 from the tilted state to the tilted state, the lock of the connecting sleeve 41 can be released, and the user can directly pull out the two charging guns 3 from the charging port on the side of the charging pile body 2 at one time, and during the pulling out process, the connecting sleeve 41 can contact with several inclined baffles 46 one by one, so the charging gun 3 can be shaken during the pulling out process, so as to shake off the water droplets attached to the charging gun 3, and directly insert it into the new energy heavy truck for use; and the distances between the two charging ports of some new energy heavy trucks may be different. At this time, the user can fix the two charging guns 3 and then rotate the threaded sleeve 43, which can drive the separation screw 42 to slide along the connecting sleeve 41, so as to adjust the distance between the two charging guns 3 and improve the adaptability. If the charging gun 3 needs to be used separately, after the user pulls out the two charging guns 3, the above adjustment steps can be repeated until the separation screw 42 moves out of the threaded sleeve 43, and the two charging guns 3 can be used separately.

[0042] like Figure 2 , Figure 6 , Figure 7 As shown, the protection component includes four guide rods 51 fixedly mounted on the inner wall of the base 1 and distributed in a linear array, the charging pile body 2 is slidably connected to the four guide rods 51, and the four guide rods 51 are all provided with a yield spring 52, and the two ends of the yield spring 52 are respectively fixedly connected to the base 1 and the charging pile body 2, the bottom surface of the charging pile body 2 is symmetrically provided with two limit grooves 53, the bottom surface of the charging pile body 2 is provided with two slide grooves 54 respectively connected to the limit grooves 53, a slide plate 55 is slidably mounted on the inner bottom surface of the base 1, and two fixing rods 56 adapted to the limit grooves 53 are fixedly mounted on the top surface of the slide plate 55, and a trigger structure corresponding to the slide plate 55 is provided on the base 1;

[0043] After the new energy heavy truck triggers the trigger structure, the pneumatic telescopic rod 57 can extend and drive the slide plate 55 to slide, so that the two fixed rods 56 on the top surface of the slide plate 55 slide from the limit groove 53 to the slide groove 54, releasing the limit on the charging pile body 2. At this time, under the elastic force of the give way spring 52, the charging pile body 2 can quickly slide along the guide rod 51, so that the charging pile body 2 can move away from the new energy heavy truck, achieve avoidance, and reduce the probability of the new energy heavy truck colliding with the charging pile body 2.

[0044] like Figure 2 , Figure 7 As shown, the trigger structure includes a pneumatic telescopic rod 57 fixedly mounted on the inner wall of the base 1, and the telescopic end of the pneumatic telescopic rod 57 is fixedly connected to the end of the slide plate 55, a bottom frame 58 is provided at the side position of the base 1, an extrusion airbag 59 is provided on the inner bottom surface of the bottom frame 58, a pressing plate 510 is slidably mounted on the inner wall of the open end of the bottom frame 58, two ends of the extrusion airbag 59 are respectively fixedly connected to the inner bottom surface of the bottom frame 58 and the bottom surface of the pressing plate 510, and the extrusion airbag 59 is connected to the pneumatic telescopic rod 57 through a conduit 511;

[0045] Due to poor performance at night, when the heavy truck driver is about to hit the charging pile body 2 without careful observation, the front wheel of the heavy truck will first press the pressure plate 510 in the parking area. When the pressure plate 510 is pressed, the extrusion airbag 59 in the bottom frame 58 can be compressed. When the extrusion airbag 59 is compressed, the gas inside it can be filled into the pneumatic telescopic rod 57 through the conduit 511.

[0046] like Figure 2 , Figure 8 , Figure 9 As shown, two receiving grooves 6 are symmetrically provided on the top surface of the base 1, and a connecting groove 7 connected to the two receiving grooves 6 is provided at the end of the top surface of the base 1, and anti-collision components are arranged on the inner sides of the two receiving grooves 6 and the connecting groove 7; the anti-collision component comprises two supporting rods 81 symmetrically fixedly installed on both sides of the inner bottom surface of the connecting groove 7, and a plurality of anti-collision plates 82 are slidably sleeved on the outer wall of the bottom end of the supporting rod 81, and the plurality of anti-collision plates 82 are connected to each other by a connecting chain 83, and the inner walls of the two receiving grooves 6 are rotatably installed with transmission telescopic rods 84 through rotating rods, and the telescopic ends of the two transmission telescopic rods 84 are respectively hinged to the two ends of the bottom surface of the uppermost anti-collision plate 82, and the inner walls of the two receiving grooves 6 away from the connecting groove 7 are provided with guide grooves 85, and the inner walls of the two guide grooves 85 are slidably installed with guide plates 86, and the two side surfaces of the charging pile body 2 are fixedly installed with spring telescopic rods 87 corresponding to the guide plates 86, and the telescopic ends of the spring telescopic rods 87 are provided with mounting grooves 88, and the inner wall of the mounting groove 88 is rotatably installed with guide wheels;

[0047] During the process of the charging pile body 2 sliding and making way along the guide rod 51, the spring telescopic rod 87 on the side of the charging pile body 2 can slide along with the charging pile body 2. When the spring telescopic rod 87 slides to the position of the guide groove 85, the spring telescopic rod 87 can extend and press the guide plate 86 in the guide groove 85, causing the guide plate 86 to slide downward along the guide groove 85 and press the lower transmission telescopic rod 84. When one end of the transmission telescopic rod 84 is pressed, it can rotate through the rotating rod, and drive the anti-collision plate 82 at the telescopic end to slide upward along the support rod 81. During the sliding process of the anti-collision plate 82, several anti-collision plates 82 in the communication groove 7 can be pulled out one by one through the connecting chain 83 and located between the two support rods 81, so that the two support rods 81, several anti-collision plates 82 and the connecting chain 83 form a protection for the charging pile body 2 to reduce the impact force.

[0048] As Figure 5 , Figure 8 , Figure 10 shown, there are two groups of warning components symmetrically arranged between the charging pile body 2 and the base 1; the warning component includes a shaft rod 91 rotatably installed on the side of the charging pile body 2, a warning rod 92 fixedly sleeved on the outer wall of the shaft rod 91, a stop rod 93 fixedly installed on the side of the charging pile body 2 corresponding to the warning rod 92, a limit telescopic rod 94 fixedly installed at the symmetric position of the side of the charging pile body 2 and the stop rod 93, a support rod 95 fixedly installed on the top surface of the base 1 corresponding to the warning rod 92, a connecting plate 96 fixedly installed at the top end of the support rod 95 corresponding to the limit telescopic rod 94, a mounting rod 97 fixedly installed on the outer wall of the support rod 95, a support spring 98 fixedly installed on the outer wall of the mounting rod 97 and adapted to the warning rod 92, a top plate 99 fixedly installed at the top end of the support spring 98, and a reflective warning plate 10 fixedly installed at the top ends of the warning rod 92 and the support rod 81;

[0049] Before the charging pile body 2 triggers the sliding and making way to the end of the guide rod 51, the limit telescopic rod 94 is in the extended state, the warning rod 92 is located between the stop rod 93 and the limit telescopic rod 94, and the reflective warning plates 10 at the top ends of the warning rod 92 and the support rod 81 can warn the heavy truck driver. After the charging pile body 2 triggers the sliding and making way, when the charging pile body 2 makes way, as the charging pile body 2 slides, the connecting plate 96 at the top end of the support rod 95 can press the limit telescopic rod 94, thereby releasing the limit on the warning rod 92. Under the action of gravity, the warning rod 92 can rotate through the shaft rod 91, causing the two warning rods 92 and the reflective warning plates 10 to rotate in opposite directions. When the warning rod 92 rotates and contacts the top plate 99, it can squeeze the support spring 98. Under the elastic force of the support spring 98, the warning rod 92 can rotate reciprocally and cooperate with the reflective warning plate 10 to warn the new energy heavy truck driver so that the new energy heavy truck driver can timely discover the danger.

[0050] The technical solution provided by the present invention is that when the entire charging pile is installed and put into use, the base 1 and the bottom frame 58 need to be embedded in the ground, and the bottom frame 58 is located in the parking area, at a certain distance from the base 1. When the user needs to charge the new energy heavy truck, he can directly charge two guns at the same time. Specifically, in the initial state, several baffles 46 are all in a vertical state, and the connecting sleeve 41 and the separating screw 42 connect the two charging guns 3, and the connecting sleeve 41 is located at the end of the inner side of the limit frame 44. The two baffles 46 at the end fix the connecting sleeve 41 through the give way grooves 410 thereon, and further lock the two charging guns 3 to avoid damage caused by arbitrary plugging and unplugging. When the user needs to use it, the charging pile body 2 can be activated for use. When the charging pile body 2 is activated, the electric push The rod 49 can be extended. Since the fixed end of the electric push rod 49 is hinged to the inner wall of the slot 45, and the telescopic end is rotatably connected to the side of the transmission disk 47, the electric push rod 49 can drive a transmission disk 47 at the end to rotate when it is extended, and several transmission disks 47 can be rotated synchronously through the connecting rod 48, so that the baffle 46 on the transmission disk 47 is rotated from a vertical state to an inclined state, and the lock of the connecting sleeve 41 can be released. The user can directly pull out two charging guns 3 from the charging port on the side of the charging pile body 2 at one time. In the process of pulling out, the connecting sleeve 41 can contact with several inclined baffles 46 one by one. Therefore, the charging gun 3 can be shaken in the process of pulling out, so as to shake off the water droplets attached to the charging gun 3, and directly insert it into the new energy heavy truck for use;

[0051] For some new energy heavy trucks, the distances between the two charging ports may be different. In this case, the user can fix the two charging guns 3 and then rotate the threaded sleeve 43 to drive the separation screw 42 to slide along the connecting sleeve 41 to adjust the distance between the two charging guns 3, thereby improving the adaptability. If the charging guns 3 need to be used separately, the user can pull out the two charging guns 3 and repeat the above adjustment steps until the separation screw 42 moves out of the threaded sleeve 43, so that the two charging guns 3 can be used separately.

[0052] If the heavy truck driver is not careful enough to observe and is about to hit the charging pile body 2 due to poor performance at night, the front wheel of the heavy truck will first press the pressure plate 510 in the parking area. When the pressure plate 510 is pressed, the squeezing airbag 59 in the bottom frame 58 can be compressed. When the squeezing airbag 59 is compressed, the gas inside can be filled into the pneumatic telescopic rod 57 through the conduit 511, so that the pneumatic telescopic rod 57 is extended and drives the slide plate 55 to slide, so that the two fixed rods 56 on the top surface of the slide plate 55 slide from the limit groove 53 to the slide groove 54, and the limit on the charging pile body 2 is released. At this time, under the elastic force of the yield spring 52, the charging pile body 2 can quickly slide along the guide rod 51, so that the charging pile body 2 can stay away from the new energy heavy truck, achieve avoidance, and reduce the probability of the new energy heavy truck hitting the charging pile body 2;

[0053] When the charging pile body 2 slides along the guide rod 51 to make way, the spring telescopic rod 87 on the side of the charging pile body 2 can slide with the charging pile body 2. When the spring telescopic rod 87 slides to the position of the guide groove 85, the spring telescopic rod 87 can extend and press the guide plate 86 in the guide groove 85, so that the guide plate 86 slides downward along the guide groove 85 and presses the transmission telescopic rod 84 at the lower part. When one end of the transmission telescopic rod 84 is pressed, it can be rotated by the rotating rod, and the anti-collision plate 82 at the telescopic end can be driven to make the anti-collision plate 82 slide upward along the support rod 81. During the sliding process of the anti-collision plate 82, the connecting chain 83 can be used to pull out the several anti-collision plates 82 in the connecting groove 7 one by one and locate between the two support rods 81, so that the two support rods 81, the several anti-collision plates 82 and the connecting chain 83 form a protection for the charging pile body 2 to reduce the impact force.

[0054] Before the charging pile body 2 is triggered to give way and slide to the end of the guide rod 51, the limiting telescopic rod 94 is in an extended state, and the warning rod 92 is located between the blocking rod 93 and the limiting telescopic rod 94, and the warning rod 92 and the reflective warning plate 10 at the top of the support rod 81 can warn the heavy truck driver. After the charging pile body 2 is triggered to give way, when the charging pile body 2 gives way, the connecting plate 96 at the top of the sliding support rod 95 of the charging pile body 2 can press the limiting telescopic rod 94, thereby releasing the limit on the warning rod 92. Under the action of gravity, the warning rod 92 can be rotated through the shaft 91, so that the two warning rods 92 and the reflective warning plate 10 rotate in opposite directions. When the warning rod 92 rotates and contacts the top plate 99, the support spring 98 can be squeezed. Under the elastic force of the support spring 98, the warning rod 92 can rotate back and forth, and cooperate with the reflective warning plate 10 to warn the new energy heavy truck driver, so that the new energy heavy truck driver can detect danger in time.
