Description

TECHNICAL FIELD

[0001] The utility model relates to battery box technical field, concretely relates to a battery box fixing device and energy storage equipment. BACKGROUND

[0002] At present, when the system needs a larger battery capacity, multiple battery boxes are usually used, in order to ensure the stability and safety of the battery box during use, multiple battery boxes need to be vertically stacked and installed into a specific mounting frame, and the mounting frame provides safety protection for the battery box. Although the mounting frame structure can be used to install and fix multiple battery boxes, there are still some problems in actual application, for example, during installation and fixation, the battery box needs to be hoisted into the mounting frame one by one, which not only complicates the operation and affects the efficiency of battery box installation and fixation, but also causes great cost in manufacturing the mounting frame, and the mounting frame is large in size and heavy in weight, causing many inconveniences in use.

[0003] In order to solve the above problems, the inventor improves the structure of the existing battery box, cancels the use of the mounting frame structure by improving the structure strength of the battery box, uses the battery box structure itself as the mounting frame, and fixes the battery boxes adjacent to each other during use, so that all the battery boxes are stacked in the vertical direction and connected as a whole, and no specific mounting frame is needed to fix the battery box.

[0004] The improved scheme of the inventor can simplify the structure, save space, reduce installation difficulty and cost, etc., and after the multiple battery boxes are vertically stacked and fixedly connected, all the battery boxes need to be transported into the customized container structure for transportation and use. At present, the front side of the container is provided with a switch door, and the multiple battery boxes are transported into the container through the switch door at the front side of the container after being vertically stacked and connected. In order to avoid the battery box from moving randomly after being placed in the container, the battery box needs to be fixed with the container. At present, the fixing method is to directly fix the mounting seat with the container, so that all the stacked and connected battery boxes are stably installed in the container. However, during actual fixation, since the stacked battery boxes have been placed in the container, only the position of the mounting seat close to the switch door side can be fixed manually. Due to the space blockage of the stacked battery boxes, the position of the mounting seat close to the rear side of the container cannot be fixed, and the rear side of the container is closed and cannot be opened to fix the rear end of the mounting seat. Therefore, it is necessary to design a fixing structure of the battery box to stably fix the battery box after being placed in the container. UTILITARIAN CONTENT

Finally, the front end of the mounting seat 1 is fixed to the bottom surface of the container 5 on the front side. The fixing can be done with bolts, etc. Since the opening and closing door 501 is in the open state at this time, the connection and fixing of the front end of the mounting seat 1 can be easily completed manually. The details of its fixing structure will not be described here.

[0044] Example 2

[0045] The difference between Example 2 and Example 1 is as follows: Figure 7 and Figure 8 As shown, in this embodiment, an anti-detachment part is provided between the abutment seat 3 and the fixed seat 2, and an elastic reset member is fixedly connected between the abutment seat 3 and the fixed seat 2. Specifically, the anti-detachment part includes mutually cooperating anti-detachment protrusions 7 and sliding protrusions 8. The anti-detachment protrusions 7 are arranged along the inclined direction of the sliding slope 201, and there are two anti-detachment protrusions 7, which are integrally formed on the left and right side walls of the fixed seat 2, respectively. Correspondingly, there are also two sliding protrusions 8, which are integrally formed on the left and right side walls of the abutment seat 3, respectively. The sliding protrusions 8 are C-shaped, and the anti-detachment protrusions 7 are located in the C-shape of the sliding protrusions 8. In addition, the elastic reset member in this embodiment includes a tension spring 9. One end of the tension spring 9 is hooked to the side wall of the fixed seat 2, and the other end of the tension spring 9 is hooked to the top surface of the horizontal section of the sliding protrusion 8. When the tension spring 9 is in its natural state, the abutment seat 3 is in a state away from the bottom surface of the container 5.

[0046] In the embodiment, by arranging the sliding protrusion 8 and the anti-disengagement protrusion 7, in the sliding process of the abutting seat 3 relative to the fixed seat 2, the anti-disengagement protrusion 7 plays an upward supporting role on the whole abutting seat 3 through the contact with the sliding protrusion 8, avoiding the disengagement of the abutting seat 3 from the fixed seat 2 in the use process, and when the anti-disengagement protrusion 7 and the sliding protrusion 8 slide with each other, the anti-disengagement protrusion 7 can play a guiding role on the sliding of the abutting seat 3 relative to the fixed seat 2, effectively improving the stability and accuracy in the sliding process of the abutting seat 3. Meanwhile, in the embodiment, by arranging the tension spring 9, when the abutting seat 3 is not driven to slide relative to the fixed seat 2 by the locking screw 4, the abutting seat 3 is in a state of being away from the bottom surface of the container 5, at this time, the mounting seat 1 can be conveniently mounted into the container 5, and the abutting seat 3 is inserted into the rear end of the insertion slot 203, so that the mounting and connection of the mounting seat 1 are more convenient and efficient.
