[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-9 The utility model provides a technical solution: a heat dissipation panel protection device, comprising a mounting frame 1 provided on the vehicle head and a heat dissipation panel 11 spaced apart and arranged inside the mounting frame 1, and further comprising:

[0029] A protective device 2 is provided on the heat dissipation panel 11;

[0030] The protective net 3 is retractably arranged inside the protective device 2 and fixedly connected to the mounting frame 1 by bolts, and is used to seal and protect the heat dissipation panel 11.

[0031] It should be noted that during operation, in May every year, the poplar trees in some areas will produce a large amount of poplar fluff. At this time, the protective net 3 needs to be installed on the mounting frame 1 to protect the heat dissipation panel 11. The protective net 3 is taken out from the inside of the protective device 2 and then fixed to the mounting frame 1 by bolts. When the poplar fluff disappears, the protective net 3 is stored in the inside of the protective device 2. The protective net 3 is retractably arranged inside the protective device 2 and fixedly connected to the mounting frame 1 by bolts to form an effective seal and protection for the heat dissipation panel 11, which can effectively prevent the poplar fluff from being sucked into the inside of the heat dissipation panel 11 and affecting the heat dissipation panel 11 and the condenser of the vehicle. The design of the protective device 2 makes the installation and disassembly of the protective net 3 simple and quick. Providing a specific storage space for the protective net 3 can reduce the loss of the protective net 3. When the protective net 3 is damaged or needs to be cleaned, it can be easily taken out of the protective device 2 for replacement or cleaning, reducing the maintenance difficulty and cost.

[0032] In one embodiment, the protective device 2 includes an installation box 21 fixed to an opening on one side of the heat dissipation panel 11, a fixing rod 22 fixed inside the installation box 21, and a box cover 23 detachably provided on the installation box 21. The protective net 3 is placed inside the installation box 21, and the protective net 3 is sleeved on the fixing rod 22.

[0033] This design, see Figure 3-9 The design of the opening on one side of the installation box 21 allows the protective net 3 to be easily put in or taken out from the opening, which greatly simplifies the installation and disassembly process, not only improves the maintenance efficiency, but also reduces the downtime caused by replacing or cleaning the protective net 3. The setting of the fixing rod 22 provides a stable support point for the protective net 3. The center of the protective net 3 is sleeved on the fixing rod 22, ensuring the stability and firmness of the installation of the protective net 3. Even if the vehicle encounters bumps or vibrations during driving, the position of the protective net 3 can be kept unchanged.

[0034] In one embodiment, a fixing plate 25 is provided on one side of the box cover 23 connected to the heat dissipation panel 11. The fixing plate 25 can be adjusted and passed through both sides of the box cover 23. A sliding groove 2302 for the fixing plate 25 to move is opened at the position of the box cover 23 corresponding to the fixing plate 25.

[0035] This design, see Figure 6 ,as well as Figure 7When the protective net 3 needs to be taken out from the inside of the installation box 21, the fixing plate 25 is removed from the heat dissipation panel 11, the box cover 23 is opened, and then the protective net 3 is taken out from the inside of the installation box 21, and then the fixing plate 25 is stored inside the box cover 23, the box cover 23 is put on the fixing rod 22, and then pushed into the interior of the installation box 21, and then the center of the protective net 3 is put on the fixing rod 22, and then the side of the protective net 3 is fixed to the heat dissipation panel 11. Since the design of the fixing plate 25 and the sliding groove 2302 allows a certain adjustment range, the box cover 23 can be conveniently stored.

[0036] In one embodiment, a limit block 251 is provided at the position where the fixing plate 25 is connected to the inner wall of the box cover 23, and a limit groove 2303 for the limit block 251 to move is provided at the position of the box cover 23 corresponding to the limit block 251. The limit block 251 is fixedly connected to the heat dissipation panel 11 by bolts, and the heat dissipation panel 11 is provided with an installation groove 1101 for placing the limit block 251.

[0037] This design, see Figure 7 The matching design of the limit block 251 and the limit groove 2303 provides additional support and limiting effect between the fixing plate 25 and the box cover 23, which not only enhances the stability of the connection between the box cover 23 and the installation box 21, but also provides mounting holes 2501 for mounting bolts on the fixing plate 25, and fixing holes 1102 for mounting bolts on the heat dissipation panel 11, which can facilitate the fixing plate 25 to be fixed on the heat dissipation panel 11, and the limit block 251 can be accurately embedded in the mounting groove 1101 on the heat dissipation panel 11 and fixedly connected by bolts, ensuring the precise positioning of the box cover 23 during the installation process, making the entire structure more solid.

[0038] In one embodiment, a fixing bolt 24 is threadedly connected to the side of the fixing rod 22 away from the installation box 21, and a limiting hole 301 is opened at the position of the protective net 3 corresponding to the fixing rod 22, and the diameter of the limiting hole 301 is smaller than the diameter of the head of the fixing bolt 24.

[0039] This design, see Figure 4-6 The head diameter of the fixing bolt 24 is larger than the diameter of the limiting hole 301, which means that when the fixing bolt 24 is tightened, its head will be tightly stuck on one side of the limiting hole 301, thereby effectively fixing the protective net 3 on the fixing rod 22, preventing the protective net 3 from loosening or falling off due to vibration or external force.

[0040] In one embodiment, a movable slot 2301 is defined at a position of the box cover 23 corresponding to the fixing rod 22 .

[0041] This design, see Figure 6The box cover 23 is movably mounted on the fixing rod 22 , and the installation position of the box cover 23 inside the installation box 21 can be easily adjusted, thereby realizing the installation and storage of the protective net 3 .
