Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery compartment technology, specifically a battery compartment modular structure. Background Technology

[0002] In various devices that require battery power, such as electric vehicles, outdoor battery swapping stations, and charging cabinets, the design of the battery compartment is crucial.

[0003] Existing battery compartments are mostly one-piece structures, which have significant limitations. Taking electric vehicles as an example, factories pre-determine the number and specifications of batteries and mass-produce battery compartments that are compatible with them. This results in battery compartments that can only accommodate a fixed number and model of batteries, and cannot be disassembled, severely lacking flexibility. In outdoor battery swapping and charging cabinet scenarios, the battery compartment is usually larger than the battery. When the cabinet is shaken or tipped over by external forces, the battery is prone to move inside the compartment and impact the compartment, which may cause battery charging failure, structural damage, or deformation of the battery compartment, affecting battery safety and lifespan. There may already be technical solutions to solve the above-mentioned technical problems. Therefore, this case aims to provide a replacement or alternative technical solution. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a modular battery compartment structure, solving the problem that most existing battery compartments are one-piece structures, which have significant limitations. Taking electric vehicles as an example, factories pre-determine the number and specifications of batteries and mass-produce battery compartments to match them. This results in battery compartments that can only accommodate a fixed number and model of batteries, and cannot be disassembled, severely lacking flexibility. In outdoor battery swapping and charging cabinet scenarios, the battery compartment is usually larger than the battery. When the cabinet is shaken or tipped over by external forces, the battery is prone to move inside the compartment, impacting the compartment and potentially causing battery charging failure, structural damage, or battery compartment deformation, affecting battery safety and lifespan.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery compartment assembly structure, comprising a first compartment, a second compartment inserted into one end of the first compartment, electric push rods embedded in the opposite side walls of the first compartment, a connecting piece mounted on the telescopic end of each electric push rod, a top plate mounted between the two connecting pieces, a junction box groove mounted on the other end of the first compartment, a pressure sensor embedded in the side wall of the top plate, a first rubber layer detachably mounted on the side wall of the top plate and on the side of the pressure sensor, and two auxiliary sliding grooves machined on the opposite side walls of the second compartment.

[0006] Preferably, the inner wall of the first compartment is fitted with three matching second rubber layers.

[0007] Preferably, a warning light is embedded in the center of the upper wall of the top plate.

[0008] Preferably, two assembly slots are machined on the lower inner wall of the second compartment, each assembly slot is equipped with a top post, each top post is equipped with a threaded rod, and each threaded rod is equipped with a toggle ring.

[0009] Preferably, each of the threaded rod end faces is equipped with a bearing, and each of the bearings is equipped with a top block.

[0010] Preferably, each of the top blocks is fitted with a rubber top.

[0011] Beneficial effects

[0012] This utility model provides a modular battery compartment structure. It offers the following advantages: This device allows for the combined use of single and double compartments, facilitating disassembly from the electric vehicle battery compartment for easy maintenance and repair. It allows for the addition of batteries of different sizes as needed, and the added batteries are effectively clamped to prevent movement within the compartment during use, thus extending battery life. This addresses the limitations of existing, mostly one-piece battery compartment structures. For example, in electric vehicles, factories pre-determine the number and specifications of batteries and mass-produce compatible battery compartments, resulting in compartments that can only accommodate a fixed number and model of batteries, lacking the flexibility to be disassembled. In outdoor battery swapping and charging cabinets, the battery compartment is typically larger than the battery. When the cabinet is shaken or tipped over, the battery can easily move within the compartment, impacting the compartment and potentially causing charging failure, structural damage, or compartment deformation, affecting battery safety and lifespan.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example: Refer to Figure 1-4 A battery compartment assembly structure includes a first compartment 1, a second compartment 2 inserted into one end of the first compartment 1, electric push rods 3 embedded in opposite side walls of the first compartment 1, a connecting piece 4 mounted on the telescopic end of each electric push rod 3, a top plate 5 mounted between two connecting pieces 4, a junction box groove 6 mounted on the other end of the first compartment 1, a pressure sensor 7 embedded in the side wall of the top plate 5, a first rubber layer 8 detachably mounted on the side wall of the top plate 5 and located on one side of the pressure sensor 7, and two auxiliary... The slide 9; three matching second rubber layers 10 are installed on the inner wall of the first compartment 1; a warning light 11 is embedded in the center of the upper wall of the top plate 5; two assembly slots are machined on the lower inner wall of the second compartment 2, each assembly slot is equipped with a top column 12, each top column 12 is equipped with a threaded rod 13, each threaded rod 13 is equipped with a toggle ring 14; each threaded rod 13 is equipped with a bearing 15 on its end face, each bearing 15 is equipped with a top block 16; each top block 16 is equipped with a rubber top 17 on its end face.

[0022] The specific working principle is as follows:

[0023] The first compartment 1 and the second compartment 2 are compatible with battery compartments of different electric vehicles. During assembly, the workers first insert the first compartment 1 and the second compartment 2 into each other. After insertion, the workers assemble the combined first compartment 1 and second compartment 2 into the battery compartment of the electric vehicle. The workers then begin assembly, placing the battery into the first compartment 1. After placement, the battery powers the vehicle. The programmable controller installed on the first compartment 1 controls the operation. The electric push rod 3 drives the connecting piece 4 installed on its telescopic end to retract, thereby causing the top plate 5 to retract and clamp the battery. As the electric push rod 3 continues to retract, the top plate 5 continuously increases the clamping force. The first rubber layer 8 installed on the top plate 5 is compressed, thus compressing the pressure sensor 7. When the pressure sensor 7 senses that the pressure has reached the set tightening pressure range, it sends a signal. The programmable controller receives the signal and sends a control command. The warning light 11 installed on the top plate 5 illuminates, and the programmable controller simultaneously controls the battery. The electric push rod 3 stops operating, firmly clamping the battery in the first compartment 1 to prevent shaking. The operator moves the actuating ring 14 to rotate the threaded rod 13 in the top column 12. The threaded rod 13 extends and retracts in the mounting groove on the second compartment 2, causing the rubber head 17 on the top block 16 to press against the top plate 5 for power-off auxiliary fixation. The bearing 15 facilitates the rotation of the threaded rod 13, improving smoothness and preventing the top block 16 from being irregularly placed in the mounting groove. When a larger battery needs to be replaced, the operator moves the actuating ring 14 to retract the threaded rod. The electric push rod 3 pushes the top plate 5 to loosen, increasing the battery volume in the first compartment 1. After the larger battery is removed, the operator repeats the above steps to clamp the battery and perform power-off auxiliary fixation. The second rubber layer 10 and the first rubber layer 8 protect the clamped battery and increase friction to improve the stability of the fastening. The junction box groove 6 facilitates the placement of the junction box, and the auxiliary sliding groove 9 facilitates the extension and retraction of the electric push rod 3 to the second compartment 2 to increase the battery volume.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
