Description

Technical Field

[0001] This utility model relates to the field of energy storage devices, and in particular to an energy storage box and a battery energy storage compartment. Background Technology

[0002] Currently, the battery equipment inside electrochemical energy storage chambers is usually configured in clusters. During use, the battery equipment has high requirements for the dustproof and waterproof performance of the energy storage chamber. For the doors of the energy storage chamber, the existing technology generally adopts a flat single door or a container door structure. Both of these door structures can achieve the waterproof sealing performance requirements, but they have their own advantages and disadvantages in terms of processing and cost.

[0003] Flat-panel single-door doors require individual battery clusters, typically operating on a one-cluster-one-door-one-lock basis. While the door body can be standardized, the cost is relatively high. Container-style door structures are relatively inexpensive, but suffer from poor sealing and strength. For example, Chinese utility model patent CN218887390U discloses an energy storage box and energy storage device. (See [link to patent details]). Figure 1 The energy storage device 1000 includes an energy storage box 100, which includes an outer shell 90 and a door 91. The door is a container door, and the container door and the energy storage compartment frame are usually welded together. The sealing and waterproofing strip relies on the exposed sealing strip. When the container door is closed, the sealing strip itself is prone to twisting. After the door body is closed and aligned, there is a possibility that the sealing strip is not tightly attached to the door body, which will lead to the sealing strip not sealing the container door well, resulting in water leakage and causing safety accidents. In addition, in addition to the possibility of the sealing strip curling and deforming, causing water leakage hazards, welded container doors are more expensive, have low welding efficiency, and the exposed locking rod affects the aesthetics.

[0004] Therefore, there is an urgent need to develop a new type of energy storage box structure to overcome the problem that the waterproof performance of existing energy storage boxes using container-style doors is limited by the deformation recovery of the external sealing strip, resulting in poor waterproof performance. At the same time, it is necessary to solve technical problems such as the impact on the entry and exit of batteries when using a double-door structure. Utility Model Content

[0005] The purpose of this utility model is to provide an energy storage box to solve the technical problems of low structural strength and poor waterproof performance when using double doors in existing energy storage boxes; at the same time, the purpose of this utility model is also to provide a battery energy storage compartment using the above-mentioned energy storage box to solve the technical problems of low structural strength and poor waterproof performance when using double doors in existing battery energy storage compartments.

[0006] To achieve the above objectives, the energy storage box of this utility model adopts the following technical solution:

[0007] An energy storage enclosure includes a main body with multiple battery cluster mounting positions arranged along the front-to-back direction. A door frame is provided on the left and / or right side of the main body, and a door is installed through the door frame. The door is a double door. The door frame includes a mounting post for hinged installation of the door and a locking post for locking and supporting the door. The locking post is located between two adjacent battery clusters and its width is smaller than the width of the mounting post so that the battery clusters at the corresponding mounting positions can enter and exit between the mounting post and the locking post. The double door includes a first door panel and a second door panel. The first door panel has a folded edge that abuts against the locking post, and the second door panel has a pressing edge for pressing against the folded edge. A door lock is provided between the locking post and the second door panel.

[0008] The beneficial effects of the above technical solution are as follows: This utility model is an invention based on the existing technical solution of energy storage box, involving element modification. Specifically, the energy storage box door provided by this utility model adopts a double-door structure. A locking post is set at the mating position of the first and second door panels. A folded edge is set on the first door panel to abut against the locking post, and a pressing edge is set on the second door panel to press against the folded edge. After the first and second door panels are mated, the folded edge presses against the locking post, and the pressing edge presses tightly against the folded edge, completing the locking of the locking post, the first door panel, and the second door panel. This ensures that when the first and second door panels are mated and locked, the locking post can provide stable support for both the first and second door panels. Simultaneously, the first and second door panels are hinged to different mounting posts. The hinge position of the first door panel to the mounting post, and the second... The hinge position between the door panel and the door mounting post, the press-fit position between the first door panel and the locking post, and the locking position between the second door panel and the locking post constitute a "four-point" locking structure. This effectively prevents the energy storage tank from experiencing localized deformation of the door during lifting or transportation, which could lead to a decrease in structural strength and affect the sealing effect. Furthermore, multiple battery cluster mounting positions are provided within the tank body. Placing the locking post between two adjacent battery clusters, with a width smaller than the width of the door mounting post, allows the locking post to provide stable support for the first and second door panels, enhancing the structural stability of the energy storage tank without hindering the entry and exit of battery clusters, ensuring the normal installation and removal of battery clusters.

[0009] Furthermore, the folded edge includes a first bent section that bends inward toward the inside of the first door panel and a second bent section that bends outward from the first bent section. When the first door panel is closed, the second bent section abuts against the outer side of the lock post.

[0010] Furthermore, the door lock includes a lock hook fixedly mounted on the lock post, and the second bent section is provided with a clearance opening to avoid the lock hook.

[0011] Furthermore, a vertical groove is provided on the outer side of the lock post, and a sealing strip is provided between the first bent section and the corresponding side wall of the groove.

[0012] Furthermore, the pressing edge includes an inner curved section that bends inward toward the second door panel. The pressing edge is formed by the inner curved section. When the second door panel is closed, the pressing edge presses onto the folded edge through the corresponding end of the inner curved section.

[0013] Furthermore, multiple lock hooks are fixedly arranged at intervals along the vertical direction of the door lock post, and the door lock also includes a movable rod that can move up and down on the second door panel and a locking pin installed on the movable rod that corresponds to the lock hook.

[0014] Furthermore, the outer side of the lock post is provided with a U-shaped profile, and the groove is formed by the U-shaped profile, with the groove opening facing away from the lock post.

[0015] Furthermore, a sealing strip is provided between the inner curved section and the corresponding outer wall surface of the U-shaped profile.

[0016] Furthermore, sealing strips are respectively provided on the door frame at the edges corresponding to the first door panel and the second door panel.

[0017] To achieve the above objectives, the battery energy storage compartment of this utility model adopts the following technical solution:

[0018] A battery storage compartment includes a storage box and battery clusters. The storage box includes a main body with multiple battery cluster mounting positions arranged along the front-to-back direction. A door frame is provided on the left and / or right side of the main body, and a door is installed through the door frame. The door is a double door. The door frame includes a door mounting post for hinged installation of the door and a locking post for locking and supporting the door. The locking post is located between two adjacent battery clusters and its width is smaller than the width of the door mounting post so that the battery clusters at the corresponding battery cluster mounting positions can enter and exit between the door mounting post and the locking post. The double door includes a first door panel and a second door panel. The first door panel has a folded edge that abuts against the locking post, and the second door panel has a pressing edge for pressing against the folded edge. A door lock is provided between the locking post and the second door panel.

[0019] The beneficial effects of the above technical solution are as follows: This utility model is an invention based on the existing technical solution of battery energy storage compartments, involving element modification. Specifically, the battery energy storage compartment provided by this utility model includes an energy storage box. The box door of the energy storage box adopts a double-door structure. A locking post is set at the mating position of the first door panel and the second door panel. A folded edge is set on the first door panel to abut against the locking post. A pressing edge is set on the second door panel to press against the folded edge. After the first and second door panels are mated, the folded edge presses against the locking post, and the pressing edge presses tightly against the folded edge, thus completing the locking between the locking post, the first door panel, and the second door panel. This allows the locking post to provide stable support for the first and second door panels when they are mated and locked. At the same time, the first and second door panels are respectively hinged to different mounting posts. The hinge between the first door panel and the mounting post... The four positions—the hinge point between the first door panel and the locking post, the press-fit point between the first door panel and the locking post, and the locking point between the second door panel and the locking post—form a "four-point" locking structure. This effectively prevents the energy storage tank from experiencing localized deformation of the door during lifting or transportation, which could lead to a decrease in structural strength and affect the sealing effect. Furthermore, multiple battery cluster mounting positions are provided within the tank body. Placing the locking post between two adjacent battery clusters, with a width smaller than the width of the door post, allows the locking post to provide stable support for the first and second door panels, enhancing the structural stability of the energy storage tank without hindering the entry and exit of battery clusters, ensuring the normal installation and removal of battery clusters.

[0020] Furthermore, the folded edge includes a first bent section that bends inward toward the inside of the first door panel and a second bent section that bends outward from the first bent section.

[0045] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0046] The technical concept of the energy storage box of this utility model is as follows:

[0047] Because the existing energy storage container doors are container-style doors, although container-style doors are a type of double-door structure, the sealing strips of container-style doors are installed on the outside of the door. When the container-style door is closed, the sealing strips themselves are prone to twisting and deformation. After the door body is closed and closed, there is a possibility that the sealing strips are not tightly attached to the door body, which will lead to the sealing strips not sealing the container-style door well, resulting in water leakage and causing safety accidents. At the same time, such a door structure is not advantageous in terms of processing costs, and the exposed locking rod affects the aesthetics.

[0048] To address the problems existing in current energy storage boxes, this utility model provides a locking column at the mating position of the first and second doors. A folded edge is provided on the first door panel to abut against the locking column, and a pressing edge is provided on the second door panel to press against the folded edge. After the first and second door panels are mated, the folded edge presses against the locking column, and the pressing edge presses firmly against the folded edge, thus completing the locking of the locking column, the first door panel, and the second door panel. This ensures that the locking column provides stable support for both the first and second door panels when they are mated and locked. Meanwhile, the first and second door panels are hinged to different door mounting columns. The hinge positions of the first and second door panels, the press-fit position of the first and second door panels to the door mounting columns, and the locking position of the second door panel to the locking column constitute a "four-point" locking structure. This effectively prevents the energy storage box from undergoing local deformation during lifting or transportation, which could lead to a decrease in structural strength and affect the sealing effect. Furthermore, multiple battery cluster mounting positions are provided in the box body. The locking columns are positioned between two adjacent battery clusters and are narrower than the width of the door mounting columns. This allows the locking columns to provide stable support for the first and second door panels, strengthening the structural stability of the energy storage box, without affecting the entry and exit of the battery clusters, ensuring the normal installation and removal of the battery clusters.

[0049] Based on the above technical concept, the embodiment of the energy storage box of this utility model is as follows:

[0050] like Figure 2-15 As shown, the energy storage enclosure includes a main body 1 and a door 2. Multiple battery cluster mounting positions are arranged along the front-to-back direction within the main body 1, and a door frame is provided on the left side of the main body 1. Figure 3 , 4 As shown, the door frame includes a door mounting post 3 and a door locking post 4. As the name suggests, the door mounting post 3 is used to install the box door 2, and the door locking post 4 is used to lock the box door onto the door locking post. The box door 2 is hinged to the door mounting post 3 via a movable hinge 5.

[0051] like Figure 5-12As shown, the cabinet door 2 is a double-door structure, including a first door panel 6 and a second door panel 7. The first door panel 6 is provided with a folded edge 8, which can abut against the door lock post 4 when the door is closed. The second door panel 7 is provided with a pressing edge 9, which can press the second door panel 7 against the folded edge 8 of the first door panel 6 when the door is closed. In addition, a door lock is provided between the second door panel 7 and the door lock post 4. The door lock includes a lock hook 10, a movable rod 11, a lock pin 12, and a lock head 13. The lock head 13 is located on the outside of the second door panel 7, the lock hook 10 is located on the outside of the door lock post 4, the movable rod 11 is located on the inside of the folded edge 8 of the second door panel 7, and the lock pin 12 is also located on the inside of the folded edge 8 of the second door panel 7. When the cabinet door 2 is closed, the position of the lock pin 12 corresponds one-to-one with the position of the lock hook 10.

[0052] Furthermore, the locking post 4 is located between two adjacent battery pack mounting positions, and the width of the locking post 4 is smaller than the width of the mounting post 3. This allows the locking post 4 to provide stable support for the first door panel 6 and the second door panel 7 without affecting the installation and removal of the battery pack.

[0053] like Figure 7-9 As shown, the folded edge 8 includes a first bent section 15 that bends inward toward the first door panel 6 and a second bent section 16 that bends outward from the first bent section 15. When the first door panel 6 is closed, it is engaged with the outer side of the lock door post 4 by the second bent section 16. Furthermore, a clearance opening 14 for avoiding the lock hook 10 is provided on the second bent section 16. The position of the clearance opening 14 corresponds one-to-one with the position of the lock hook 10, and the shape of the clearance opening 14 is adapted to the outer surface of the lock hook 10. The first door panel 6 also includes an inner sealing plate 17, and a sealing strip pressing space is provided between the perimeter of the first door panel 6 and the inner sealing plate 17.

[0054] like Figure 10-12 As shown, the pressing edge 9 includes an inwardly bent section of the second door panel 7, which forms the pressing edge 9. When the second door panel is closed, the end of the inwardly bent section presses against the second bent section 16 of the folded edge 8. The second door panel 7 also includes an inner sealing plate 17, and a sealing strip pressing space is provided between the second door panel 7 and the inner sealing plate 17.

[0055] like Figure 6As shown, a U-shaped profile 18 is also provided on the lock door pillar 4. The U-shaped profile 18 forms a groove, with the groove opening facing away from the lock door pillar 4. To further improve the waterproof sealing effect of the energy storage box, a sealing strip 19 is provided between the first bent section 15 of the folded edge 8 and the groove wall. At the same time, a sealing strip 19 is also provided between the inner bent section and the corresponding side groove wall of the groove. The U-shaped profile 18 is fixed to the outer surface of the lock door pillar 4 by fastening screws. Lock hook fixing holes 20 are provided on the bottom wall of the groove and on the lock door pillar 4. Multiple lock hooks 10 are spaced apart along the vertical direction of the lock door pillar 4 at the bottom of the groove. Fasteners pass through the lock hook fixing holes 20 on the lock door pillar 4 and the bottom wall of the groove to fix the lock hooks to the lock door pillar 4.

[0056] Furthermore, to ensure the waterproof sealing performance between the cabinet door and the door frame, sealing strips are provided at the edges of the door frame corresponding to the first door panel 6 and the second door panel 7.

[0057] Furthermore, grounding stakes 21 are also provided at the bottom of the first door panel 6 and the second door panel 7.

[0058] When the door needs to be closed, first close the first door panel 6. The clearance 14 on the second bending section 16 avoids the lock hook 10, so that the second bending section 16 of the first door panel 6 presses against the lock pillar 4. Then close the second door panel 7. The end of the inner bending section presses against the second bending section 16. Then turn the lock head 13. The movable rod 11 moves so that the lock pin 12 extends and locks with the lock hook 10. This can achieve the locking of the first door panel 6, the second door panel 7 and the lock pillar 4. With this technical solution, the waterproof sealing performance of the entire energy storage box is improved.

[0059] The energy storage box using the technical solution of this utility model also includes other embodiments.

[0060] In the above embodiments, the energy storage box is provided with a door frame and a door only on the left side of the box body. In other embodiments, the door frame and door may be provided only on the right side of the box body, or the door frame and door may be provided on both the left and right sides of the box body.

[0061] The specific implementation of the battery energy storage compartment of this utility model is as follows: The battery energy storage compartment includes an energy storage box and a battery cluster. The battery cluster is installed in the battery cluster mounting position in the energy storage box. The specific structure of the energy storage box is the same as the energy storage box structure in the above-described embodiment of the energy storage box, and will not be repeated here.
