Description

Technical Field

[0001] This utility model relates to the field of battery box support technology, and in particular to a support for a new energy vehicle battery box. Background Technology

[0002] In the production, warehousing and distribution of new energy vehicle batteries, the transportation safety of battery boxes directly determines the quality and reliability of the batteries in subsequent use. During transportation, they face multiple risks such as bumps, impacts, vibrations, friction, and temperature fluctuations. As a core tool for protecting battery boxes and ensuring stable loading, the battery box support frame used for transportation must simultaneously meet three core requirements: high-strength shock absorption and protection, safe heat dissipation, and convenient loading, unloading and fixing. Traditional transport brackets often use foam filling, simple rubber pads, or single springs as cushioning components. When transport vehicles encounter potholes or sudden braking, the battery boxes are prone to longitudinal bouncing and lateral displacement. The cushioning components can only absorb part of the impact force and lack a positioning guide structure, causing the battery boxes to collide with the inner wall of the bracket. This can easily lead to scratches and deformation of the outer shell, and even misalignment of internal cells and breakage of the electrode tabs. New energy battery boxes still generate slight heat through self-discharge when not in operation. However, traditional transport brackets are mostly fully enclosed metal frames or sealed plastic structures. The airtightness leads to poor air circulation, and the brackets have no ventilation channels, so heat cannot dissipate. This can accelerate battery aging or even cause electrolyte leakage during high temperatures in summer or long-distance transport. Furthermore, there is no active cooling auxiliary structure, relying only on natural ventilation of the frame, which cannot meet the heat dissipation requirements of transporting multiple battery boxes densely. Some brackets completely enclose the battery boxes for protection, further blocking heat dissipation and exacerbating local overheating problems. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a support bracket for automotive new energy battery boxes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a support bracket for a new energy vehicle battery box, comprising two symmetrically arranged shock-absorbing boxes, with multiple symmetrically arranged fixed covers equidistantly arranged on the bottom surface of the inner side of each shock-absorbing box, a shock-absorbing spring fixedly connected to the top surface of each fixed cover, a shock-absorbing plate fixedly connected to the top surface of each shock-absorbing spring, multiple positioning pins equidistantly fixed to both sides of the top surface of each of the two shock-absorbing boxes, a main support plate provided on the top surface of each of the two shock-absorbing boxes, pin holes corresponding to the positioning pins being opened on the main support plate, and multiple ventilation openings equidistantly opened on both sides of the main support plate.

[0005] Preferably, the outer wall of the main support plate is fixed with multiple lifting lugs, and the top surface of the main support plate is symmetrically provided with two sets of fixing bolts for detachable fixing to the top surface of the shock-absorbing box. The outer walls on both sides of the main support plate are fixed with multiple connecting blocks at equal intervals, and the connecting blocks are provided with fixing holes.

[0006] Preferably, the top surface of the main support plate has multiple lifting grooves equidistantly spaced, corresponding to the shape of the damping plate, and the inner walls of the lifting grooves are symmetrically provided with limiting grooves on both sides. The outer walls of both sides of the damping plate are provided with protrusions corresponding to the shape of the limiting grooves.

[0007] Preferably, the main support plate is in the shape of a mountain, and the mountain shape of the main support plate includes vertical plates in the middle and on both sides. Two connecting plates are symmetrically arranged on both sides of the protrusion in the middle of the main support plate. Multiple L-shaped mounting plates are fixedly connected to the top surface of the connecting plates at equal intervals. Mounting blocks are fixedly connected to the connecting plates between the multiple L-shaped mounting plates. Fixing bolts are passed between the mounting blocks and the main support plate.

[0008] Preferably, the two connecting plates have guide grooves on their opposite surfaces, and two sets of cooling fans are symmetrically arranged in the guide grooves. The opposite ends of the cooling fans are coaxially fixed together by a rotating shaft, and a sliding block is slidably disposed in the guide groove on the rotating shaft.

[0009] Preferably, a fixing block is sleeved in the middle section of the rotating shaft, a motor is fixedly connected to the bottom surface of the fixing block, a drive gear is coaxially fixedly connected to the output shaft of the motor, a driven gear meshing with the drive gear is coaxially fixedly connected to the rotating shaft, a linear motor is fixedly connected to the bottom surface of the motor, and a slide block for sliding the linear motor is installed between the opposite surfaces of the two damping boxes.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model utilizes the cooperation between the shock-absorbing spring and the shock-absorbing plate within the shock-absorbing box. The shock-absorbing spring absorbs the longitudinal impact force during transportation, while the shock-absorbing plate buffers the impact force by moving up and down. Simultaneously, the protrusions on both sides of the shock-absorbing plate slide in conjunction with the limiting groove in the lifting groove of the main support plate, limiting the lateral displacement of the shock-absorbing plate. This reduces the longitudinal bounce and lateral displacement of the battery box, improving the shock absorption and protection effect, and thus achieving multi-dimensional buffer protection for the battery box. Furthermore, the cooperation between the positioning pin on the top surface of the shock-absorbing box and the fixing holes on the battery's peripheral fixing plate allows for quick initial positioning of the battery box by aligning the fixing holes with the positioning pin and inserting it, facilitating subsequent further fixing operations and improving... This design improves the ease of battery box installation and positioning, enabling precise alignment between the battery box and the bracket. Then, through the coordination of the cooling fan within the guide slot of the connecting plate and the ventilation openings on both sides of the main support plate, the cooling fan accelerates airflow, and the ventilation openings form air convection channels. Simultaneously, the linear motor drives the cooling fan to slide along the slide rail, expanding the heat dissipation range and enhancing airflow within the bracket, thus improving active cooling efficiency. This allows for comprehensive heat dissipation during the dense transport of multiple battery boxes. Ultimately, this design solves the problems of battery box collision damage caused by rudimentary traditional bracket buffer components and battery aging and leakage due to the lack of effective heat dissipation structures, improving battery box transport safety, heat dissipation stability, and ease of loading and unloading.

[0016] Working principle: When using this utility model, firstly, the battery box to be transported is placed on the top surface of the main support plate 3, aligning the fixing holes on the fixing plates around the battery with the positioning pins 2 on the top surface of the shock-absorbing box 1. The fixing holes are inserted into the positioning pins 2 to complete the initial precise positioning of the battery box. Then, the main support plate 3 is detachably fixed to the top surface of the shock-absorbing box 1 using the fixing bolts at both ends of the top surface of the main support plate 3. At the same time, the battery box can be further reinforced with external ropes or buckles using the fixing holes on the connecting blocks 7 on both sides of the main support plate 3 to prevent longitudinal movement of the battery box during transportation and ensure a stable connection between the battery box and the bracket. Then... To provide shock absorption and protection, during transportation, when the transport vehicle encounters potholes and longitudinal bumps, the shock-absorbing spring 15 inside the shock-absorbing box 1 will elastically deform due to the impact force, absorbing part of the longitudinal impact force. At the same time, the shock-absorbing plate 5 at the top of the shock-absorbing spring 15 moves up and down with the impact force, forming a buffer support for the battery box. During this process, the protrusions on both sides of the shock-absorbing plate 5 will slide along the limiting groove 9 on the inner wall of the lifting groove of the main support plate 3, limiting the lateral displacement of the shock-absorbing plate 5, thereby preventing the battery box from swaying laterally with the shock-absorbing plate 5, preventing the battery box from colliding with the inner wall of the bracket, and reducing the risk of scratches, deformation and misalignment of the internal cells. This achieves multi-dimensional shock absorption protection for the battery box; finally, active heat dissipation is carried out. Considering that the new energy battery box generates slight heat through self-discharge during transportation, the cooling fan 6 in the guide groove of the connecting plate 4 is activated. The cooling fan 6 rotates to accelerate the airflow inside the bracket, and the ventilation openings 8 on both sides of the main support plate 3 form an air convection channel to expel the heat generated by the battery box from the outside of the bracket. At the same time, the linear motor 13 on the bottom of the motor is activated. The linear motor 13 slides along the slide block 11 between the two shock-absorbing boxes 1, driving the fixed block 14 and the rotating shaft to move synchronously. The cooling fans 6 at both ends of the rotating shaft move with the sliding block 12 in the guide groove. The sliding mechanism expands the heat dissipation range of the cooling fan 6, ensuring that each battery box can be effectively cooled when multiple battery boxes are transported densely. This prevents battery aging or electrolyte leakage caused by heat accumulation in a confined environment and ensures stable temperature during battery box transportation. Throughout the transportation process, the mountain-shaped structure of the main support plate 3 enhances the overall rigidity of the bracket, preventing bending and deformation of the bracket during stacked transportation. The lifting lugs 10 on the outer perimeter of the main support plate 3 facilitate loading, unloading, and handling of the bracket using forklifts, cranes, and other tools, improving the convenience of transportation operations and ensuring safe and stable transportation of the battery boxes throughout the entire process. At this point, the device is in use.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
