Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery compartments, in particular to a double-hinge door lock device, and further to an energy storage battery compartment. Background Art
[0002] Energy storage battery compartments play a significant role in modern life. They offer advantages such as stable voltage and current, fast charge and discharge response, and immunity to external influences. Furthermore, their simple structure makes them flexible, portable, and reliable. However, the internal space of energy storage battery compartments is limited. Utilizing this limited space to accommodate more batteries allows the compartment to store more power, making it more competitive in the market. Therefore, a dual-hinge design for the battery compartment door lock can effectively conserve battery compartment space, significantly increasing the utilization of the compartment's external space.
[0003] Currently, the main door lock for energy storage battery compartments is a single-hinge design. While single-hinge door locks offer advantages such as simplicity and ease of installation, they do not conserve space in high-energy-density battery compartments. Traditional single-hinge door locks have upright channel steel fixed to the battery compartment crossbeam and cannot rotate. This partially obstructs the internal storage space, forcing the battery compartment to be longer to accommodate the battery modules. This, in turn, increases the overall size of the battery compartment and reduces internal space utilization. Utility Model Content
[0004] The purpose of the present utility model is to propose and design a double-hinged door lock device and an energy storage battery compartment, in order to solve the problem that the column channel steel in the existing battery compartment partially blocks the internal placement space, resulting in the battery compartment size having to be lengthened to ensure the assembly of the battery module. The column channel steel of the double-hinged door lock device can be rotated and then restored and fixed after the battery module is installed in the battery compartment, avoiding obstruction when installing the battery module, and can effectively reduce the length of the battery compartment, so that more electrical components can be assembled on the outside of the battery compartment, thereby increasing its use value.
[0005] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a double-hinge door lock device, including a column bent steel plate, a column channel steel and a cabin door, the column bent steel plate and the column channel steel are connected by a first hinge, the column bent steel plate is located on the inner side of the column channel steel, one of the leaves of the first hinge is connected to the back side of the column channel steel, the other leaf of the first hinge is connected to the column bent steel plate, the column channel steel and the cabin door are connected by a second hinge, the second hinge is located in the groove of the column channel steel, one of the leaves of the second hinge is connected to the cabin door, and the other leaf of the second hinge is connected to the column channel steel. By setting a first hinge on the inner side of the column channel steel and rotating it with the column bent steel plate through the first hinge, the column channel steel can be rotated outward, and the hatch can also be rotated around the second hinge on the column channel steel, so as to avoid it when placing the battery module and avoid obstruction at the door. When the size of the battery module is certain, it can be completely placed in without leaving a large amount of remaining space in the length direction due to obstruction, thereby effectively reducing the length of the battery compartment.
[0006] Furthermore, an avoidance groove is provided on the bent steel plate of the column, and one of the blades of the first hinge is fixed in the avoidance groove. When the column channel steel rotates, an avoidance space is formed, so that the column channel steel can rotate more significantly.
[0007] Furthermore, the column bent steel plate has an outer end plate, and the back of the column channel steel abuts against the outer end plate in the closed state. The outer end plate of the column bent steel plate has a blocking and limiting effect on the column channel steel. When the column channel steel rotates to close, the outer end plate of the column bent steel plate blocks the column channel steel, and the two fit together to form a closed state.
[0008] Furthermore, the first hinge is arranged close to the left side of the column channel steel, and the second hinge is arranged close to the right side of the column channel steel, so as to reserve a rotation space.
[0009] Furthermore, the second hinge includes a fixed blade and a rotating blade. The fixed blade is fixed to the bottom plate of the column channel steel, while the rotating blade is fixed to the hatch door. The rotating blade and the fixed blade are connected by a rotating shaft. The hatch door has a mounting slot at the end, and the rotating blade is located in the mounting slot. The mounting slot and the groove of the column channel steel provide installation space for the second hinge, ensuring a neat and beautiful exterior surface of the hatch door.
[0010] Furthermore, the fixed blade includes a fixed portion, a support portion, and a hinge portion. The fixed portion is fixed within the column channel steel, the hinge portion is spaced apart from the fixed portion, and the support portion connects the hinge portion and the fixed portion. The rotating shaft is mounted on the hinge portion at one end away from the support portion. The support portion provides space for the door to rotate, preventing the installation of the mounting slot from interfering with the rotation.
[0011] Furthermore, when the hatch door is closed, the column channel steel and the column bent steel plate are fixedly connected by a right-angle connector, thereby fixing the column channel steel in position and ensuring the door is securely closed.
[0012] In addition, the utility model also provides an energy storage battery compartment, including the above-mentioned double-hinged door lock device, and also includes a battery compartment frame, the double-hinged door lock device is installed on the battery compartment frame, and multiple double-hinged door lock devices are arranged on the battery compartment frame.
[0013] It can be seen from the above technical solutions that the present invention has the following advantages:
[0014] This solution provides a double-hinged door lock device and an energy storage battery compartment. The column channel steel of the double-hinged door lock device can be rotated and then restored and fixed after the battery module is installed in the battery compartment, avoiding obstruction when installing the battery module. It can effectively reduce the length of the battery compartment, allowing more electrical components to be installed on the outside of the battery compartment, thereby increasing its use value.

[0022] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Specific implementation method 1
[0024] like Figures 1 to 4 As shown, this specific embodiment provides a double-hinge door lock device, including a column bent steel plate 1, a column channel steel 2 and a hatch 3, the column bent steel plate 1 and the column channel steel 2 are connected by a first hinge 4, the column bent steel plate 1 is located on the inner side of the column channel steel 2, one of the leaves of the first hinge 4 is connected to the back of the column channel steel 2, and the other leaf of the first hinge 4 is connected to the column bent steel plate 1, the column channel steel 2 and the hatch 3 are connected by a second hinge 5, the second hinge 5 is located in the groove of the column channel steel 2, one of the leaves of the second hinge 5 is connected to the hatch 3, and the other leaf of the second hinge 5 is connected to the column channel steel 2.
[0025] The column-bent steel plate 1 is provided with an escape groove, in which one of the blades of the first hinge 4 is fixed. When the column channel steel 2 rotates, an escape space is formed, allowing the column channel steel 2 to rotate more significantly. The column-bent steel plate 1 has an outer end plate. In the closed state, the back of the column channel steel 2 abuts against the outer end plate. The outer end plate of the column-bent steel plate 1 has a blocking and limiting effect on the column channel steel 2. When the column channel steel 2 rotates and closes, the outer end plate of the column-bent steel plate 1 blocks the column channel steel 2, and the two fit together to form a closed state. The first hinge 4 is arranged near the left side of the column channel steel 2, and the second hinge 5 is arranged near the right side of the column channel steel 2. Specifically, the second hinge 5 includes a fixed blade and a rotating blade. The fixed blade is fixed to the bottom plate of the column channel steel 2, and the rotating blade is fixed to the hatch 3. The rotating blade and the fixed blade are connected by a rotating shaft. The end of the hatch 3 is provided with a mounting groove 6, and the rotating blade is located in the mounting groove 6. The mounting groove 6 and the groove of the column channel steel 2 provide installation space for the second hinge 5, ensuring that the outer surface of the hatch 3 is neat and beautiful. The fixed blade includes a fixed portion 51, a support portion 52, and a hinge portion 53. The fixed portion 51 is fixed in the column channel steel 2. The hinge portion 53 is spaced apart from the fixed portion 51. The support portion 52 connects the hinge portion 53 and the fixed portion 51. The rotating shaft is installed on the hinge portion 53 and is away from one end of the support portion 52. The provision of the support portion 52 provides space for the hatch 3 to rotate, avoiding the rotation being affected by the provision of the mounting groove 6.
[0026] In addition, when in the closed state, the column channel steel 2 and the column bent steel plate 1 are fixedly connected by right-angle connectors 7 and bolts, and the column channel steel 2 is fixed in position to ensure the reliability of the hatch 3 when closed.
[0027] Its working principle is as follows: the column channel steel 2 is connected to the column bent steel plate 1 through the first hinge 4, so that the column channel steel 2 can be rotated ninety degrees relative to the column bent steel plate 1, and the hatch 3 is connected to the column channel steel 2 through the second hinge 5, so that the hatch 3 can be rotated ninety degrees relative to the column channel steel 2. When assembling the battery module, the hatch 3 and the column channel steel 2 are pulled outward and rotated, thereby opening the hatch 3 and the column channel steel 2 and fully opening them; when the battery module is installed, the column channel steel 2 is rotated ninety degrees to restore it to its original state, and fixed to the column bent steel plate 1 with a right-angle connector 7 and bolts, and the hatch 3 is rotated ninety degrees to close it.
[0028] The traditional column channel steel 2 partially blocks the internal placement space, see Figure 4 , the column channel steel 2 blocks the placement entrance of the battery module placement rack. However, this solution allows the column channel steel 2 of the double-hinged door lock device to rotate, and then restore and fix it after the battery module is installed in the battery compartment, avoiding obstruction during battery module installation and effectively reducing the length of the battery compartment.
