Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and more specifically, to a gravity-based door opening and closing structure and solid-state battery production equipment containing the same. Background Technology

[0002] As batteries advance towards higher energy density, researchers have begun incorporating sulfides into solid-state batteries to significantly improve their energy density. However, in the production of sulfide-containing solid-state batteries, the sulfides within the partially encapsulated battery are susceptible to reaction with moisture in the air, generating toxic and flammable hydrogen sulfide gas. Therefore, current production of sulfide-containing solid-state batteries requires sealed environments. However, solid-state battery production involves multiple steps, each requiring operation within a different sealed enclosure. These enclosures typically have very limited space, placing extremely high demands on the design of the door opening and closing structure. The door opening and closing structure must not only achieve efficient sealing within a limited space but also ensure convenient and reliable operation. Therefore, designing an efficient, reliable, and cost-effective door opening and closing structure within a limited space, while ensuring good sealing, has become a pressing technical challenge in the production of sulfide-containing solid-state batteries. Utility Model Content

[0003] This utility model provides a gravity-based door opening and closing structure. Through structural optimization design, it simplifies the operation of opening and closing the door, reduces space occupancy, improves sealing performance, and eliminates the need for an additional drive device, thus reducing the complexity and cost of the equipment. It also provides a solid-state battery production equipment that includes the above-mentioned gravity-based door opening and closing structure.

[0004] On the one hand, this utility model provides a gravity-based door opening and closing structure, which includes at least two parallel slide rails on a door frame, with an opening and closing door between adjacent slide rails. Each slide rail has a slide groove along its length, and the slide groove includes a sliding groove and an inclined locking groove at the end of the sliding groove. The opening and closing door is slidably connected to the slide groove. When the opening and closing door moves to the end of the inclined locking groove under its own weight, the opening and closing door seals the door frame.

[0005] This utility model discloses a gravity-based door opening and closing structure. Through the setting of slide rails and slide grooves, the door can slide along the slide rails under its own weight. When the door moves to the end of the inclined slot of the slide groove, the door seals the door frame. Thus, the door achieves automatic sealing by utilizing its own weight, simplifying the operation of opening and closing the door, improving sealing performance, and eliminating the need for an additional drive device, thereby reducing the complexity and cost of the equipment.

[0006] Furthermore, each of the slide rails has two slide grooves arranged along its length.

[0007] In the above technical solution, by setting two slide rails along the length of each slide rail, and having two parts on each side of the door slide in a sliding connection with the slide rails, the door can be opened and closed more smoothly during movement, thereby improving the reliability and service life of the entire door structure.

[0008] Furthermore, the switch door is provided with first friction-reducing components on both sides. The first friction-reducing components are slidably connected to the slide groove. When the first friction-reducing components slide to the end of the inclined slot, the switch door seals the door frame.

[0009] In the above technical solution, the movement resistance of opening and closing the door can be reduced by setting the first wear-reducing component.

[0010] Furthermore, the end of the switch door is provided with a follower plate, which is located on the side of the switch door away from the door frame, and the first wear-reducing member is located on both sides of the follower plate.

[0011] In the above technical solution, by setting follower plates at one or both ends of the door, the strength of the door can be increased and the installation of the first wear-reducing component can be facilitated. This allows for more flexible motion control and better load distribution, thereby improving the reliability and service life of the entire door structure.

[0012] Furthermore, the follower plate is provided with a second wear-reducing component, which is located on one side of the first wear-reducing component and between the switch door and the slide rail.

[0013] In the above technical solution, by setting a second friction-reducing component on the follower plate, the friction between the door and the slide rail during the opening and closing process can be further reduced, achieving low-friction, high-precision motion control, improving the smoothness of the door's movement, and thus improving the reliability and service life of the entire door structure.

[0014] Furthermore, the first anti-friction component is a roller or a slider; and / or, the second anti-friction component is a roller.

[0015] In the above technical solution, rollers and sliders are commonly used components to reduce friction. By setting the first friction-reducing component as a roller or slider and the second friction-reducing component as a roller, the movement resistance of opening and closing the door can be reduced.

[0016] Furthermore, the gravity-based door opening and closing structure also includes a linear guide mechanism, which includes a guide rail fixed to the door frame and a movable plate slidably disposed on the guide rail. The movable plate and the follower plate adjacent to it are rotatably connected by a rotating shaft.

[0017] During the opening and closing of the door, the first anti-friction component has a certain displacement in the direction perpendicular to the plane of the door when it enters or exits the inclined slot. By connecting the moving plate of the linear guide mechanism and the follower plate close to it through a rotating shaft, the displacement requirement in this direction can be met. At the same time, the guiding effect of the guide rail further improves the movement accuracy and stability of the door, ensuring that the door can reach the predetermined position more smoothly and accurately during the opening and closing process, thereby achieving a better sealing effect and service life.

[0018] Furthermore, the switch door includes a door body and a sealing frame located around the door body, the periphery of which is fitted to the door frame.

[0019] In the above technical solution, the periphery of the sealing frame fits tightly against the door frame, which can improve the sealing between the door and the door frame and prevent hydrogen sulfide from leaking from the gap between the door and the door frame.

[0020] As another configuration, the door includes a door body and a seal located on one side of the door body, and the door body and the door frame are sealed together by the seal.

[0021] In the above technical solution, by placing the seal between the door body and the door frame, the sealing performance between the door and the door frame can be improved, and hydrogen sulfide can be prevented from leaking from the gap between the door and the door frame.

[0022] On the other hand, this utility model provides a solid-state battery production equipment, which includes the above-mentioned gravity-based opening and closing door structure.

[0023] The beneficial effects of this utility model are as follows: This utility model discloses a gravity-based door opening and closing structure. Through the setting of slide rails and slide grooves, the door can slide along the slide rails under its own weight. When the door moves to the end of the inclined slot of the slide groove, the door seals the door frame. Thus, the door achieves automatic sealing by utilizing its own weight, simplifying the operation of opening and closing the door, improving the sealing performance, and eliminating the need for an additional drive device, reducing the complexity and cost of the equipment. It is particularly suitable for occasions that require frequent opening and closing of doors and have high requirements for sealing performance.

[0024] The solid-state battery production equipment of this invention, due to its gravity-based opening and closing door structure, can not only achieve a highly efficient sealing effect and reduce space occupancy, but also improve production efficiency, reduce energy consumption, improve safety, and reduce production risks.

[0027] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0028] Please refer to Figure 1-5 This utility model discloses a gravity-based door opening and closing structure, which includes at least two parallel slide rails 2 on a door frame 1, and an opening and closing door 3 between adjacent slide rails 2. Each slide rail 2 has a slide groove 21 along its length direction. The slide groove 21 includes a sliding groove 211 and an inclined slot 212 located at the end of the sliding groove 211. The opening and closing door 3 is slidably connected to the slide groove 21. When the opening and closing door 3 moves to the end of the inclined slot 212 under its own weight, the opening and closing door 3 seals the door frame 1.

[0029] Figure 1-3 The diagram shows three sets of door opening and closing structures 0. The slide rails 2 are fixed to the door frame 1. The number of slide rails 2 can be set as needed, but at least two are required. Figure 1-3The slide rail 2 shown is five in number. It can be understood that two adjacent doors 3 can share one slide rail 2. It can be understood that the slide groove 21 serves as a guide and limiter. Preferably, the length direction of the slide rail 2 is arranged in the vertical direction, and the inclined groove 212 is located at the lower end of the slide groove 211. The end of the inclined groove 212 is the lower end of the inclined groove 212.

[0030] Specifically, the door 3 is rectangular. Figure 3 , 5 The illustrated switchable door 3 includes a door body 31 and a sealing frame 32 surrounding the door body 31. The periphery of the sealing frame 32 fits tightly against the door frame 1, improving the sealing performance between the switchable door 3 and the door frame and preventing hydrogen sulfide leakage from the gap between the switchable door 3 and the door frame 1. Specifically, the sealing frame 32 is a sealing rubber frame. Alternatively, the switchable door 3 includes a door body 31 and a seal located on one side of the door body 31. The door body 31 and the door frame 1 are sealed together by the seal, improving the sealing performance between the switchable door 3 and the door frame and preventing hydrogen sulfide leakage from the gap between the switchable door 3 and the door frame 1. Specifically, the seal is a sealing rubber ring.

[0031] In addition, the door 3 is equipped with a handle 33, which makes it easy to move the door 3 upward to release the seal on the door frame 1.

[0032] In this utility model, the gravity-based door opening and closing structure allows the door 3 to move downwards along the slide rail 2 under its own weight. When the part of the door 3 connected to the slide rail 21 is not located at the end of the inclined slot 212, the door frame 1 is in an unsealed state. When the door 3 continues to move downwards until the part of the door 3 connected to the slide rail 21 is located at the end of the inclined slot 212, the door frame 1 is sealed by the door 3. When it is necessary to open the door 3, simply push the door 3 upwards.

[0033] Furthermore, such as Figure 2-4 As shown, each slide rail has two grooves along its length.

[0034] In the above technical solution, by setting two slide grooves 21 along the length of each slide rail 2, and having two parts on each side of the door 3 slidably connected to the slide grooves 21, the door 3 can move more smoothly, thereby improving the reliability and service life of the entire door structure.

[0035] Furthermore, the switch door 3 is provided with first friction-reducing parts 4 on both sides. The first friction-reducing parts 4 are slidably connected to the slide groove 21. When the first friction-reducing parts 4 slide to the end of the inclined slot 212, the switch door 3 seals the door frame 1.

[0036] Specifically, the first anti-friction component 4 is a roller or a slider, and the figure shows a roller. It can be understood that when the first anti-friction component 4 is located in the slide groove 21 and not at the end of the inclined slot 212, the door frame 1 is in an unsealed state; when the first anti-friction component 4 moves to the end of the inclined slot 212, it is limited here by the inclined slot 212, and the door frame 1 is sealed by the door opening and closing 3.

[0037] In addition, it is understood that there are two first wear-reducing components 4 on each side of the switch door 3. The two first wear-reducing components 4 can be respectively set at the upper and lower ends or non-upper and lower ends of one side of the switch door 3. The distance between the two first wear-reducing components 4 is adapted to the distance between the ends of the two inclined slots 212. The two sliding grooves 21 allow the two first wear-reducing components 4 on one side of the switch door 3 to move in them respectively.

[0038] In the above technical solution, the movement resistance of the opening and closing door 3 can be reduced by setting the first wear-reducing component 4, thereby improving the reliability and service life of the entire opening and closing door structure.

[0039] Furthermore, such as Figure 2 As shown, the end of the switch door 3 is provided with a follower plate 5, which is located on the side of the switch door 3 away from the door frame 1, and the first wear-reducing member 4 is located on both sides of the follower plate 5.

[0040] Understandably, follower plates 5 can be installed at one or both ends of the switch door 3. In the above technical solution, by installing follower plates 5 at the ends of the switch door 3, the strength of the switch door 3 can be increased, and the installation of the first wear-reducing component 4 can be facilitated. This allows for more flexible motion control and better load distribution, thereby improving the reliability and service life of the entire switch door structure.

[0041] Furthermore, such as Figure 3 , 5 As shown, the follower plate 5 is provided with a second wear-reducing component 6, which is located on one side of the first wear-reducing component 4 and between the switch door 3 and the slide rail 2.

[0042] Specifically, the second friction-reducing component 6 is preferably a roller. In the above technical solution, by setting the second friction-reducing component 6 on the follower plate 5, the friction between the door 3 and the slide rail 2 during the movement can be further reduced, achieving low-friction, high-precision motion control, improving the smoothness of the door 3's movement, and thus improving the reliability and service life of the entire door structure.

[0043] Furthermore, such as Figure 1-5As shown, the gravity-based door opening and closing structure also includes a linear guide mechanism, which includes a guide rail 7 fixed on the door frame 1 and a movable plate 8 slidably disposed on the guide rail 7. The movable plate 8 and the follower plate 5 adjacent to it are rotatably connected by a rotating shaft 9.

[0044] Understandably, the guide rail 7 is fixed to the door frame 1 via a frame or plate (not shown in the figure); to reduce friction, a bearing (not shown in the figure) can be installed on the follower plate 5, and the rotating shaft 9 is located in the bearing. During the movement of the opening and closing door 3, the first anti-friction component 4 has a certain displacement in a direction perpendicular to the plane of the opening and closing door 3 when it enters or exits the inclined slot 212. By rotating the moving plate 8 of the linear guide mechanism and the follower plate 5 adjacent to it through the rotating shaft 9, the displacement requirement in this direction can be met. Simultaneously, the guiding effect of the guide rail 7 further improves the movement accuracy and stability of the opening and closing door 3, ensuring that the opening and closing door 3 can reach the predetermined position more smoothly and accurately during movement, thereby achieving better sealing effect and service life.

[0045] This utility model discloses a solid-state battery production equipment, which includes the aforementioned gravity-based opening and closing door structure.

[0046] The solid-state battery production equipment of this invention features a gravity-based door structure, which not only achieves a highly efficient sealing effect, ensuring that hydrogen sulfide leakage does not occur during solid-state battery production, thus improving safety and reducing production risks, but also closes the door based on its own gravity, eliminating the need for an additional closing drive device. This design reduces space occupancy and energy consumption.
