Description

Technical Field

[0001] This utility model relates to the field of heavy-duty truck auxiliary equipment, and in particular to a foldable heavy-duty truck energy storage rack. Background Technology

[0002] In the field of heavy-duty truck transportation and energy storage equipment applications, heavy-duty trucks often need to be equipped with large energy storage devices to meet the needs of long-term operation or emergency power supply. The storage and transportation of energy storage devices rely on specialized load-bearing structures. Traditional heavy-duty truck energy storage racks are mostly fixed frame designs. Although they can achieve basic load-bearing functions, the fixed structure cannot be adjusted in size during idle or transportation, resulting in a large amount of space being occupied during storage and increasing storage management costs. The problem of low space utilization is even more prominent when multiple energy storage racks are transported at the same time.

[0003] In existing technologies, the folding and unfolding operations of some structures are complex, requiring a large number of bolts for fixation. Folding operations require specialized tools and consume a lot of manpower, which cannot meet the needs of rapid deployment and storage in heavy truck operation scenarios and reduces the ease of use of the equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a foldable heavy-duty truck energy storage rack, which aims to solve the problems in the existing technology that "the folding and unfolding of some structures is complicated, requires professional tools, and cannot meet the needs of rapid deployment and storage in heavy-duty truck operation scenarios".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foldable heavy-duty truck energy storage rack, including a support frame, wherein multiple sets of support frames are provided, and a connecting seat is fixedly connected to the outer side of each set of support frames. A support column is rotatably connected to the outer side of the connecting seat. Multiple sets of support columns are provided, and a support shaft is rotatably connected to the adjacent end of two adjacent sets of support columns. A base plate is fixedly connected to the upper part of the support column, and multiple sets of positioning holes are opened through the outer side of the support column. A positioning component is inserted into the inner wall of the positioning hole.

[0006] The positioning component includes a connector that is inserted into the inner wall of a positioning hole. A limiting groove is formed on the outer side of the connector. A housing is inserted into the outer side of the connector. Operating components are slidably connected to the upper and lower inner walls of the housing. A guide rod is vertically fixedly connected to the inner wall of the housing. The operating component slides on the outer side of the guide rod. A spring is provided between the two sets of operating components. Limiting rods are alternately fixedly connected to the outer sides of the two sets of operating components. The limiting rods engage with the limiting groove.

[0007] As a further description of the above technical solution:

[0008] The connector is U-shaped.

[0009] As a further description of the above technical solution:

[0010] The operating end of the operating component extends to the outside of the housing.

[0011] As a further description of the above technical solution:

[0012] The support frame is configured in a T-shape.

[0013] As a further description of the above technical solution:

[0014] The lower part of the connecting seat near the connection point with the support column is horizontally positioned to support the lower part of the support column.

[0015] As a further description of the above technical solution:

[0016] The limiting rod is designed in an L-shape.

[0017] As a further description of the above technical solution:

[0018] The upper part of the base plate has a groove.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the energy storage rack can be quickly folded and unfolded by rotating the connecting seat and the support column. In the unfolded state, it can stably support the energy storage equipment and meet the usage requirements. When idle or in transport, the positioning component can be released to rotate and fold multiple sets of support columns along the support axis, which greatly reduces the overall volume, reduces the storage space occupied, and reduces space loss and transportation costs during transportation. It is especially suitable for the need for efficient utilization of loading space in heavy truck transportation scenarios.

[0021] 2. In this utility model, the positioning component uses a plug-in connection between the connector and the positioning hole, combined with a locking structure between the limiting rod and the limiting groove, which can quickly lock the unfolded state of the support column. The spring provides a continuous elastic force to the limiting rod, ensuring that the limiting rod and the limiting groove are tightly locked together, effectively preventing the support column from loosening or shifting during the load-bearing process. Furthermore, adjacent support columns are connected by a support shaft, which, together with the stable support of the T-shaped support frame, forms a stable structure with multiple points of force, improving the load-bearing strength and stability of the energy storage rack, and can safely support large energy storage equipment for heavy trucks.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 3This utility model provides an embodiment of a foldable heavy-duty truck energy storage rack, including a support frame 1. Multiple sets of support frames 1 are provided, offering evenly distributed fixing points for the installation of support columns 3. This allows the multiple sets of support columns 3 to form a symmetrical and stable force-bearing system, adapting to the large-scale and heavy-duty requirements of heavy-duty truck energy storage equipment. Connecting seats 2 are fixedly connected to the outer sides of each set of support frames 1, providing a rotatable connection structure for the folding and unfolding of the support columns 3. This ensures that the support columns 3 can flexibly rotate around the connecting seats 2, enabling the energy storage rack to switch between different forms. The outer side of the connecting seats 2 is rotatably connected to the support columns 3, forming a foldable frame structure. When unfolded, it constitutes a stable support skeleton, providing an installation foundation for the base plate 4 and bearing the weight of the energy storage equipment. When folded, it can rotate along the support axis 6 and the connecting seats 2, reducing the overall volume. The support columns 3 are... There are multiple sets of support columns 3, with a support shaft 6 rotatably connected to one end of each adjacent set of support columns 3, connecting the two sets of support columns 3 into a single, interconnected whole. This ensures that the two connected sets of support columns 3 can be folded and unfolded synchronously, enhancing the overall rigidity of the connected sets of support columns 3 and improving the structural load-bearing capacity. A base plate 4 is fixedly connected to the upper part of the support column 3, serving as the direct load-bearing platform for the energy storage device. The support column 3 is kept horizontal by the mutual compression of two adjacent sets of base plates 4. Multiple sets of positioning holes 7 are opened through the outer side of the support column 3, providing insertion and positioning points for the positioning components 5. Through cooperation with the positioning components 5, the unfolding angle and position of the support column 3 are locked, preventing it from rotating or shifting during the load-bearing process and ensuring load-bearing stability. The positioning components 5 are inserted into the inner wall of the positioning holes 7.

[0031] Reference Figure 2 , Figure 4 and Figure 5 The positioning component 5 includes a connector 51, which is inserted into the inner wall of the positioning hole 7. The connector 51 is U-shaped and can be simultaneously inserted into the positioning holes 7 of two adjacent sets of support columns 3 to achieve mechanical connection between the two sets of support columns 3, restrict their relative rotation, and lock them in the unfolded state. A limit groove 57 is provided on the outer side of the connector 51, and a housing 52 is inserted into the outer side of the connector 51 to provide a closed installation space for components such as the operating component 53, spring 54, and guide rod 55. The operating component 53 is slidably connected to both the upper and lower inner walls of the housing 52. The operating end of the operating component 53 extends to the outside of the housing 52, making it convenient for the operator to press and operate directly without the need for complicated tools. When folded, the positioning hole 7 on the support column 3 is aligned with the corresponding hole on the support frame 1, and fixed by the insertion of the positioning component 5, realizing the quick locking and unlocking of the positioning component 5, improving the ease of operation. The inner wall of the housing 52 is vertically fixedly connected to the guide rod 55, which restricts the movement direction of the operating component 53 and prevents the operating component 53 from deviating during movement. The operating component 53 slides on the outside of the guide rod 55.

[0032] Reference Figure 3 - Figure 5 A spring 54 is installed between the two sets of operating parts 53. In its natural state, the two sets of operating parts 53 are pushed outward to separate them, causing the limiting rod 56 to insert into the limiting groove 57, forming a stable locking and fixing. This ensures that the positioning component 5 remains locked when there is no external force. When the operating part 53 is pressed, the spring 54 is compressed and stores elastic potential energy. When the operating part 53 is released, the spring 54 releases its potential energy to drive the operating part 53 to reset, realizing the automatic locking of the limiting rod 56, improving the convenience of operation and the reliability of locking. The two sets of operating components 53 are staggered and fixedly connected to limiting rods 56 on their outer sides. The limiting rods 56 are L-shaped and mechanically clamp the insert 51 to restrict its axial movement, preventing it from falling out of the positioning hole 7. The two sets of operating components 53 are symmetrically arranged, and the limiting rods 56 connected to the upper set of operating components 53 are used to insert into the lower limiting groove 57, and the limiting rods 56 connected to the lower set of operating components 53 are used to insert into the upper limiting groove 57. The limiting rods 56 and the limiting grooves 57 are engaged. The support frame 1 is T-shaped with a large bottom contact area, which can provide a stable support base for the overall structure and disperse the vertical pressure brought by the energy storage device. The lower part of the connecting seat 2 near the connection with the support column 3 is horizontally set to support the lower part of the support column 3. Two positioning holes 7 are opened on the outer side of the right set of support columns 3 of the two adjacent sets of support columns 3. The upper part of the base plate 4 is provided with a groove, which can limit the bottom of the energy storage device and improve the stability and safety of the device placement.

[0033] Working principle: During use, the base plate 4 on the upper part of the support column 3 forms a flat bearing platform. The operator places the heavy truck energy storage equipment on the base plate 4. The groove opened on the upper part of the base plate 4 fits with the bottom of the energy storage equipment, which plays a limiting role and ensures the stability of the equipment placement. The weight of the energy storage equipment is transferred to the support column 3 through the base plate 4. The support column 3 distributes the load to the connecting seat 2 and the support frame 1. The T-shaped support frame 1, with its large bottom contact area, evenly transmits the pressure to the mounting surface, forming a stable bearing system with multi-point force to ensure that it can safely support the large energy storage equipment for heavy trucks.

[0034] When the energy storage rack is idle or needs to be transported, the operator presses the two sets of operating parts 53 extending from the positioning component 5 to the outside of the outer shell 52 by hand. The two sets of operating parts 53 move inward along the guide rod 55, compressing the middle spring 54 and storing elastic potential energy. Since the limiting rod 56 connected to the upper set of operating parts 53 is inserted into the lower limiting groove 57, and the limiting rod 56 connected to the lower set of operating parts 53 is inserted into the upper limiting groove 57, multiple sets of limiting rods 56 are simultaneously disengaged from the limiting groove 57, releasing the lock on the connector 51.

[0035] Then, pull the connector 51 out of the positioning hole 7 to unlock the support column 3. At this time, push the support column 3 upward to make it rotate around the connecting seat 2 and the support shaft 6. Multiple sets of support columns 3 move closer to each other and finally fold into a state that fits with the support frame 1. Then, align the U-shaped connector 51 of the positioning component 5 with the corresponding positioning hole 7 on the two adjacent sets of support columns 3 and insert it into them. Secure the support column 3 firmly by installing the housing 52 to prevent it from rotating or shifting during the load-bearing process, reduce the overall volume, and facilitate storage and transportation.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
