Technical Field

[0001] The present invention relates to the technical field of radiation shielding covers, and particularly to a radiation shielding cover for a charging device of an electric vehicle swapping station. Background Art

[0002] New energy vehicles have the advantages of low maintenance cost, low noise and high efficiency. At the same time, they also have the advantages of low usage cost and being more environmentally friendly. When new energy vehicles are in use, they need to use an electric vehicle swapping station. When the swapping station is working, the discharged battery in the vehicle is taken out and placed in the battery compartment, and then a fully charged battery is installed in the vehicle. When the swapping station charges the discharged battery, there is a large amount of radiation around the swapping station. At this time, a radiation shielding cover for the charging device is needed; For example, a shielding device for passive attenuation of electromagnetic radiation and including multiple units with the publication number of CN110998971B. Each unit includes multiple resonators spaced apart from each other. The unit is arranged in multiple unit cells, and each unit cell includes a common loop that surrounds at least two adjacent units among the multiple units. The multiple unit cells all have an asymmetric structure. Therefore, the shielding cover device has a negative refractive index for at least one selected frequency, thereby enabling the passive attenuation of electromagnetic radiation at the at least one selected frequency; Another example is a radiator shielding cover with the publication number of CN213491571U, where a shielding cover is installed on the radiator. The radiator shielding cover of the present utility model effectively prevents radio frequency from leaking out through space by setting a shielding cover between the radiator and the human body, and has a simple structure and low cost; There is also a spatial electromagnetic wave radiation shielding cover with the publication number of CN205071607U. The spatial electromagnetic wave radiation shielding cover includes a shielding sleeve with at least one end open, an observation window is provided on the shielding sleeve, and the shielding sleeve is also connected to a grounding wire, and the grounding wire is connected to a grounding clip. Using the electromagnetic shielding sleeve provided by the present utility model can not only achieve the shielding function of electromagnetic wave interference, but also realize the functions of observing an indicator light and operating buttons without opening the electromagnetic shielding sleeve. The electromagnetic signal shielding bag provided by the embodiments of the present utility model has the advantages of simple structure, low production cost, and can meet both engineering environments and laboratory test requirements; During the operation of the battery swapping station, it is necessary to load and unload batteries into and out of the battery compartment. Therefore, the shielding cover needs to be able to work and be stored quickly.

[0014] Preferably, a torsion spring for elastic reset is fixedly connected to the surface of the connecting shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the vertical plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The radiation shielding cover of the charging equipment of the vehicle battery swapping station adopts a novel structural design, and the specific content is as follows: (1)For the radiation shielding cover of the charging equipment in the vehicle battery swapping station, initially, the long pin is located near the connecting shaft. At this time, it is convenient for the operator to quickly swap the battery through the battery compartment. After the battery swapping, the motor starts, and the motor drives the threaded rod to rotate. At this time, under the action of the long plate and the limit post, the long pin moves in the vertical direction. When the long pin descends, it will pull open the shielding cover body on the surface of the connecting shaft, that is, expand the shielding cover body. Finally, the long pin moves to the lower side of the vertical plate, making the shielding cover body fully expand, achieving the purpose of radiation protection; Further, during the movement of the long pin, the limit post enables the long pin to move only in the vertical direction, improving the stability; (2)For the radiation shielding cover of the charging equipment in the vehicle battery swapping station, initially, when the shielding cover body on the surface of the connecting shaft unfolds, the connecting shaft will be driven to rotate.

When the knocking plate moves, it drives the fixed block to slide inside the vertical plate. At this time, the limit rod enables the fixed block and the knocking plate to move only in the horizontal direction. At the same time, the connecting spring will be compressed by the fixed block. When the first gear with a non-full gear structure and the tooth block are not engaged, the knocking plate returns to its original position under the action of the connecting spring and the fixed block. Repeating the above process, the knocking plate makes a reciprocating circular motion on the surface of the vertical plate. At this time, the knocking plate can strike the sounding piece again and again, making the sounding piece emit a sound, which is convenient to remind the personnel after battery swapping to evacuate; Further, when the first gear rotates, it intermittently drives the rotating shaft and the fan to rotate through the second gear. When the fan rotates, it accelerates the air flow, so that the dust no longer adheres to the shielding cover body, which is convenient for the later cleaning by the staff. When the rotating shaft rotates, the side connecting block makes the rotating shaft rotate more stably; Furthermore, when the shielding cover body unfolds and the connecting shaft rotates, the torsion spring will be stretched. When it is necessary to swap the battery again, just make the motor rotate in reverse. At this time, the long plate and the long pin rise. Then the connecting shaft and the shielding cover body lose the pulling force. At this time, the connecting shaft rotates in reverse under the action of the torsion spring. When the connecting shaft rotates in reverse, it will wind up the shielding cover body, facilitating the next unfolding work. When the connecting shaft rotates in reverse, it will drive the rotating shaft and the fan to rotate again through the second gear, optimizing the dust removal effect.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 10 , the present invention provides the following technical solutions: A radiation shielding cover for a charging device of an electric vehicle battery replacement station: Embodiment 1: By providing a shielding cover body 8 that can be unfolded and closed, the purpose of radiation protection is achieved, as shown in Figures 1 - 3 and Figure 8 shown: It includes a bottom plate 1, on the upper surface of the bottom plate 1 is bolted a battery replacement base station 24, and on the upper surface of the bottom plate 1 is welded a vertical plate 2, and on the upper surface of the bottom plate 1 is bolted a motor 3; A radiation shielding cover for a charging device of an electric vehicle battery replacement station further includes: The long pin 6 is slidably arranged inside the vertical plate 2, and the vertical plates 2 are symmetrically distributed about the center of the battery swapping base station 24. A long plate 5 is fixedly connected to the surface of the long pin 6. The connecting shaft 7 is rotatably arranged inside the vertical plate 2, and a shielding cover body 8 is fixedly connected by winding around the surface of the connecting shaft 7. The shielding cover body 8 is made of conductive fiber material; The protection frame 15 is fixedly connected to the outer wall of the vertical plate 2, and a sounding piece 16 is fixedly connected inside the protection frame 15. A striking plate 13 corresponding to the sounding piece 16 one by one is movably arranged on the surface of the vertical plate 2; The rotating shaft 20 is rotatably arranged inside the vertical plate 2, and a fan 23 is fixedly connected to the end of the rotating shaft 20.

[0020] The output end of the motor 3 is fixedly connected with a threaded rod 4, and the threaded rod 4 is in threaded connection with the long plate 5. The long pins 6 are symmetrically distributed about the center of the long plate 5. The connecting shafts 7 correspond to the long pins 6 one by one, and a shielding cover body 8 is fixedly connected to the surface of the long pin 6.

[0021] Limit posts 11 corresponding to the long pins 6 one by one are fixedly connected to the inner wall of the vertical plate 2, and the limit posts 11 penetrate through the inside of the long pins 6. Limit blocks 9 corresponding to the vertical plates 2 one by one are fixedly connected to the surface of the connecting shaft 7, and the surface of the limit blocks 9 is attached to the inner wall of the vertical plate 2.

[0022] Initially, the long pin 6 is located at a position close to the connecting shaft 7, above the vertical plate 2. At this time, the shielding cover body 8 is in a closed state, which is convenient for the operator to quickly swap the battery through the battery compartment. After the battery swapping, the motor 3 is started, and the motor 3 drives the threaded rod 4 to rotate. At this time, under the action of the long plate 5 and the limit post 11, the long pin 6 moves in the vertical direction. When the long pin 6 descends, it will pull open the shielding cover body 8 on the surface of the connecting shaft 7. At this time, the connecting shaft 7 rotates (the torsion spring 10 is stretched), that is, the shielding cover body 8 is unfolded. Finally, the long pin 6 moves to the lower side position of the vertical plate 2, making the shielding cover body 8 fully unfolded, achieving the purpose of radiation protection. When the battery needs to be swapped again, the motor 3 can be rotated back. At this time, the long plate 5 and the long pin 6 rise, and then the connecting shaft 7 and the shielding cover body 8 lose the pulling force. At this time, the connecting shaft 7 rotates back under the action of the torsion spring 10. When the connecting shaft 7 rotates back, it will wind up the shielding cover body 8, facilitating the next unfolding work.

[0023] Embodiment 2: By arranging the striking plate 13 and the sounding piece 16, the whole device has a reminder function. Thus, when the shielding cover body 8 is unfolded, the surrounding personnel can be made to leave the battery swapping compartment, as Figures 4 - 7 shown: The surface of the connecting shaft 7 is fixedly connected with a first gear 12. The upper surface of the knocking plate 13 is fixedly provided with tooth blocks 14 corresponding to the first gear 12 at equal intervals. The side surface of the knocking plate 13 is fixedly connected with a fixed block 17, and the fixed block 17 is slidably arranged inside the vertical plate 2. And a limiting rod 18 corresponding to the fixed block 17 one by one is fixedly connected to the inner wall of the vertical plate 2.

[0024] The limiting rod 18 penetrates through the inside of the fixed block 17, and a connecting spring 19 for elastic reset is fixedly connected to the surface of the fixed block 17. And the other side of the connecting spring 19 is fixedly connected to the inner wall of the vertical plate 2. The first gear 12 is of a non-full gear structure, and the protective frame 15 is of a mesh structure.

[0025] Initially, when the shielding cover body 8 on the surface of the connecting shaft 7 unfolds, the connecting shaft 7 will be driven to rotate. Then the connecting shaft 7 drives the first gear 12 to rotate. At this time, under the action of the first gear 12 and the tooth blocks 14, the knocking plate 13 moves in a direction away from the sounding piece 16. When the knocking plate 13 moves, it drives the fixed block 17 to slide inside the vertical plate 2. At this time, the limiting rod 18 makes the fixed block 17 and the knocking plate 13 move only in the horizontal direction. At the same time, the connecting spring 19 will be squeezed by the fixed block 17. And when the first gear 12 of the non-full gear structure and the tooth blocks 14 are not engaged, the knocking plate 13 returns to its original position under the action of the connecting spring 19 and the fixed block 17. Repeating the above process, the knocking plate 13 makes a reciprocating circular motion on the surface of the vertical plate 2. At this time, the knocking plate 13 can strike the sounding piece 16 again and again, making the sounding piece 16 emit a sound, which is convenient to remind the personnel after battery replacement to evacuate. And the protective frame 15 is of a mesh structure, which can not only protect the sounding piece 16 from false sounding, but also transmit sound well, so that the personnel near the battery replacement compartment will not affect the closing work of the shielding cover body 8.

[0026] Embodiment 3: Different from Embodiment 2, by arranging the fan 23, the dust on the surface of the shielding cover body 8 can be cleaned, as Figures 9 - 10 shown: The rotating shaft 20 penetrates through the inside of the vertical plate 2, and a second gear 21 corresponding to the first gear 12 is fixedly connected to the surface of the rotating shaft 20. And a side connecting block 22 is fixedly connected to the surface of the rotating shaft 20, and the side connecting blocks 22 are distributed on both sides of the vertical plate 2.

[0027] A torsion spring 10 for elastic reset is fixedly connected to the surface of the connecting shaft 7, and the other side of the torsion spring 10 is fixedly connected to the inner wall of the vertical plate 2.

[0028] When the first gear 12 rotates, it intermittently drives the rotating shaft 20 and the fan 23 to rotate through the second gear 21. When the fan 23 rotates, the flow of air is accelerated, preventing dust from adhering to the shielding cover body 8, which facilitates the cleaning by the staff in the later stage. When the rotating shaft 20 rotates, the side connecting block 22 makes the rotation of the rotating shaft 20 more stable. During the closing process of the shielding cover body 8, as the long pin 6 rises and the connecting shaft 7 rotates under the action of the torsion spring 10, the first gear 12 also drives the second gear 21 to rotate, and the fan 23 will work again, optimizing the dust removal effect.

[0029] Working principle: When using the radiation shielding cover of the charging equipment for the vehicle swapping station, first place the device at the position where work needs to be carried out. According to Figures 1 - 10 , initially, the long pin 6 is located near the connecting shaft 7 and on the upper side of the vertical plate 2. At this time, the shielding cover body 8 is in a closed state, facilitating the operator to quickly swap the battery through the battery compartment. After the battery swap, the motor 3 is started, and the motor 3 drives the threaded rod 4 to rotate. At this time, under the action of the long plate 5 and the limit post 11, the long pin 6 moves in the vertical direction. When the long pin 6 descends, it will pull open the shielding cover body 8 on the surface of the connecting shaft 7, that is, expand the shielding cover body 8. Finally, the long pin 6 moves to the lower side position of the vertical plate 2, making the shielding cover body 8 fully expanded, achieving the purpose of radiation protection. When battery swapping is required again, just rotate the motor 3 in reverse. At this time, the long plate 5 and the long pin 6 rise, and then the connecting shaft 7 and the shielding cover body 8 lose the pulling force. At this time, the connecting shaft 7 rotates under the action of the torsion spring 10. When the connecting shaft 7 rotates, it will wind up the shielding cover body 8, facilitating the next expansion work; Initially, when the shielding cover body 8 on the surface of the connecting shaft 7 expands, the connecting shaft 7 will be driven to rotate. Then the connecting shaft 7 drives the first gear 12 to rotate. At this time, under the action of the first gear 12 and the tooth block 14, the knocking plate 13 moves away from the sounding piece 16. When the knocking plate 13 moves, it drives the fixed block 17 to slide inside the vertical plate 2. At this time, the limit rod 18 makes the fixed block 17 and the knocking plate 13 move only in the horizontal direction. At the same time, the connecting spring 19 will be compressed by the fixed block 17. When the first gear 12 with a non-full gear structure and the tooth block 14 are not engaged, the knocking plate 13 returns to its original position under the action of the connecting spring 19 and the fixed block 17. Repeating the above process, the knocking plate 13 makes a reciprocating circular motion on the surface of the vertical plate 2. At this time, the knocking plate 13 can strike the sounding piece 16 again and again, making the sounding piece 16 emit a sound, which is convenient to remind the personnel to evacuate after the battery swap; When the first gear 12 rotates, it intermittently drives the rotating shaft 20 and the fan 23 to rotate through the second gear 21. When the fan 23 rotates, the flow of air is accelerated, preventing dust from adhering to the shielding cover body 8, which facilitates the cleaning by the staff in the later stage.

[0030] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.
