[0024] It should be noted that the terms "first," "second," and the like in the specification and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof, for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or that are inherent to these processes, methods, products, or apparatus.

[0025] The present invention is described in further detail below with reference to the accompanying drawings:

[0026] Example 1

[0027] The utility model provides a bracket for a charging pile, comprising a beam unit 1 and a connecting beam 2; the beam unit 1 comprises a tray 11, a front beam 12 is provided on one side of the tray 11, and a rear beam 13 is provided on the other side, the front beam 12 and the rear beam 13 are provided with connecting holes, the connecting beam 2 is provided on the side of the front beam 12 away from the rear beam 13, the front beam 12 and the rear beam 13 are both fixedly connected to the tray 11, and the connecting beam 2 is fixedly connected to the front beam 12.

[0028] Specifically, if Figure 1 As shown, the crossbeam unit 1 includes a tray 11, a front crossbeam 12, a rear crossbeam 13, and a support beam 14. The front crossbeam 12 is arranged at the upper end of the tray 11, and the rear crossbeam 13 is arranged at the lower end of the tray 11. The front crossbeam 12 and the rear crossbeam 13 are riveted to the tray 11 through connectors. In this embodiment, the connectors are anti-loosening bolts. Anti-loosening bolts are bolts with special anti-loosening functions. When tightened, they generate a strong reaction force and friction, thereby preventing backward movement and achieving an anti-loosening effect. If the charging pile is subjected to a large impact or vibration during use, the anti-loosening bolts can effectively prevent the crossbeam unit from loosening, thereby increasing its service life.

[0029] The front crossbeam 12 and the rear crossbeam 13 have the same structural dimensions. The difference between them is that one is located at the upper end of the pallet 11 and the other is located at the lower end of the pallet 11. The axis of the front crossbeam 12 and the axis of the rear crossbeam 13 are parallel to each other, and they can jointly withstand forces and moments in different directions, thereby improving the stability and load-bearing capacity of the entire bracket. In addition, the parallelism of the front crossbeam 12 and the rear crossbeam 13 facilitates precise assembly and positioning, reducing errors and deviations. During use, regular inspection and maintenance are carried out to ensure the stability and safety of the structure. The support beam 14 is fixedly mounted on the pallet 11, and the axis of the support beam 14 is parallel to the axis of the front crossbeam 12.

[0030] A side of the tray 11 close to the support beam 14 is provided with an escape hole 15 , and a plurality of the escape holes 15 are fixedly mounted on the tray 11 .

[0031] like Figure 2 As shown, the tray 11 is provided with escape holes 15 on one side near the support beam 14. These holes are evenly distributed throughout the tray 11 and have a diameter of 6-8 mm. In this embodiment, the escape holes have a diameter of 7 mm. These holes are used not only to avoid components but also for fixing, connecting, or transmitting signals. The diameter of the escape holes directly affects the realization of these functions. The 7 mm escape holes allow the support beam 14 and tray 11 to be detachably connected via connectors, preventing them from falling or becoming loose.

[0032] The diameter of the connecting holes on both sides of the front crossbeam 12 and the rear crossbeam 13 is 5-7 mm.

[0033] like Figure 3 As shown, the diameters of the connecting holes on both sides of the front crossbeam 12 and the rear crossbeam 13 are both 6mm in this embodiment, which is compatible with the connecting parts. The connecting parts of the connecting holes on both sides of the front crossbeam 12 are different in size from the connecting parts of the connecting holes in the middle section of the front crossbeam 12. In other words, the anti-loosening bolts on both sides are M6 in size. The M6 ​​connector can provide a stronger fastening effect. In application scenarios that need to withstand large loads or vibrations, it can better maintain the stability of the connection and reduce downtime and maintenance costs caused by connection failure. Finally, manually tightening the connector of this size can provide a better feel, making the installation process smoother. In this embodiment, the connecting parts are all anti-loosening bolts, and the difference is the size.

[0034] Connecting beam 2 is mounted on one side of the front crossbeam 12 and is threadedly connected to the front crossbeam 12 via connectors. One end of connecting beam 2 is detachably connected to the front crossbeam 12, while the other end is connected to the charging pile frame. Connecting beam 2 primarily enhances the integrity and rigidity of the overall structure, improving stability and load-bearing capacity while reducing deformation and displacement.

[0035] The crossbeam unit 1 and the connecting beam 2 are detachably connected. Traditional connection methods may require complex welding or permanent fastening operations, which are not only time-consuming and labor-intensive, but also often cause many problems if errors or adjustments are required during installation. However, the detachable connection allows installers to operate more flexibly on site. For example, when assembling the crossbeam unit 1 and the connecting beam 2, workers can easily align them with the corresponding connection points and quickly complete the installation through simple mechanical connection methods such as bolts and snap-fit ​​connections. This convenience significantly shortens the installation time of a single charging pile, thereby improving installation efficiency overall.

[0036] The advantages of detachable connections are even more pronounced for mass production management. On the production line, individual components can be manufactured and processed separately and then quickly assembled together during assembly. This modular production approach not only facilitates quality control and management but also effectively improves production efficiency. Different production teams can focus on producing their own components, which are then assembled into complete brackets using standardized detachable connections. Furthermore, detachable components can be packaged and transported more compactly during transportation, reducing shipping space and costs while also minimizing the risk of damage to the components during transport.

[0037] The thickness of the pallet 11 is 1.3-1.7 mm. In this embodiment, the thickness of the pallet 11 is 1.5 mm, and the thickness of an ordinary pallet is 1.2 mm. The pallet 11 with a thickness of 1.5 mm has a higher load-bearing capacity than the pallet 11 with a thickness of 1.2 mm, making the pallet 11 more stable when bearing heavy objects. During long-term use, the pallet 11 with a thickness of 1.5 mm can better resist wear and scratches, thereby extending its service life. When impacted by external forces, the pallet 11 with a thickness of 1.5 mm can better absorb impact energy and reduce the possibility of damage. At the same time, the pallet 11 with a thickness of 1.5 mm can provide more stable structural support, reducing the failure of the pallet 11 due to deformation or warping, which helps to ensure the stability and safety of the pallet during storage and transportation. Due to the improved durability and stability, the pallet 11 with a thickness of 1.5 mm requires less maintenance and replacement, thereby reducing overall operating costs.

[0038] The thickness of the front crossbeam 12 is 1.8-2.2 mm. Specifically, in this embodiment, the thickness of the front crossbeam 12 is 2 mm, which is increased compared to the previous 1.2 mm thickness. When the charging pile is subjected to an unexpected side impact, such as a vehicle collision or collision with a heavy object, the thicker front crossbeam 12 can better resist deformation.

[0039] According to the principle of material mechanics, the bending section modulus of the front crossbeam 12 is proportional to the square of the thickness of the front crossbeam 12. Assuming that the width of the front crossbeam 12 remains unchanged, the bending section modulus of the original 1.2mm thick front crossbeam is , when the thickness becomes 2mm, the new bending section modulus is , the width of the front crossbeam 12 is , for a rectangular cross-section beam, the bending section modulus is:

[0040]

[0041] but ,

[0042]

[0043] That is, the anti-bending ability is increased by 2.78 times, which makes the charging pile less likely to be damaged when facing external forces, and improves the safety and service life of the charging pile.

[0044] In summary, the utility model provides a bracket for a charging pile, comprising a beam unit 1 and a connecting beam 2; the beam unit 1 comprises a tray 11, a front beam 12 is provided on one side of the tray 11, and a rear beam 13 is provided on the other side, the front beam 12 and the rear beam 13 are provided with connecting holes, the connecting beam 2 is provided on the side of the front beam 12 away from the rear beam 13, the front beam 12 and the rear beam 13 are both fixedly connected to the tray 11, and the connecting beam 2 is fixedly connected to the front beam 12. The front beam 12 and the rear beam 13 play an important supporting and connecting role in the bracket structure. Increasing their thickness can improve their own strength and rigidity. By increasing the thickness of the tray 11 to increase the weight, the tray 11 can better resist the pressure from above. The heavier tray 11 can provide more stable support and reduce the risk of deformation or damage due to uneven force.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
