[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0029] Example

[0030] See also Figures 1 to 9 In this embodiment, a RV rear compartment ventilation system structure is provided, including a vehicle body 1, a mounting groove 2 is provided on the vehicle body 1, a mounting plate 3 is provided in the mounting groove 2, and a fan 4 is provided at the bottom of the mounting plate 3. When ventilation is performed, the fan 4 is started, and the fan 4 can realize the gas exchange between the inside and outside of the vehicle body 1 through the mounting groove 2 to realize ventilation;

[0031] A sealing cover 5 is provided at the upper end of the mounting plate 3, and an outer protective structure 6 is provided on the outer side of the sealing cover 5. When ventilation is performed, the sealing cover 5 is opened, and the outer protective structure 6 on the outer side thereof can isolate external debris, thereby preventing the external debris from entering the mounting groove 2, thereby achieving protection, and it will not affect ventilation;

[0032] In addition, an inner protective structure 8 is provided at the outer earmuff at the lower end of the vehicle body 1 and located at the fan 4. The outer protective structure 6 and the inner protective structure 8 cooperate with each other to prevent debris, mosquitoes, etc. from entering the vehicle body 1 to the greatest extent, thereby improving the protective effect. The inner protective structure 8 is set as a structure that is easy to disassemble, and it is very convenient to install and disassemble, which is conducive to cleaning the mesh cover 82 and the internal fan 4.

[0033] The sealing cover 5 includes a cover plate 52 and an electric push rod 51. The electric push rod 51 is installed on the upper end of the mounting plate 3. The cover plate 52 is arranged on the top of the electric push rod 51. The outer diameter of the cover plate 52 is larger than the inner diameter of the mounting groove 2. The extension of the electric push rod 51 drives the cover plate 52 to move upward, thereby realizing the connection between the mounting groove 2 and the outside for ventilation. On the contrary, the cover plate 52 seals the mounting groove 2.

[0034] An outer protective structure 6 is provided at the lower end of the cover plate 52. The outer protective structure 6 includes a protective net 61 and a sealing plate 62. The protective net 61 is an annular structure, the upper end of which is fixed to the lower side of the cover plate 52, and the outer side wall thereof is slidably connected to the inner wall of the mounting groove 2. When the cover plate 52 moves up and down, the protective net 61 moves together. After the cover plate 52 moves up, the protective net 61 blocks the mounting groove 2 from the external space and blocks debris. At the same time, the mesh holes thereon can achieve ventilation. An annular sealing plate 62 is provided at the lower end of the protective net 61. The outer side wall of the sealing plate 62 is located in the groove 7 provided on the inner wall of the mounting groove 2. The two are slidably connected. The sealing plate 62 further improves the sealing effect of the protective net 61.

[0035] The inner protection structure 8 includes a fixing sleeve 81 and a mesh cover 82. The fixing sleeve 81 is mounted on the bottom of the vehicle body 1. The mesh cover 82 is snap-connected with the fixing sleeve 81, so that the mesh cover 82 can be conveniently installed and removed from the fixing sleeve 81. The outer wall of the fixing sleeve 81 is symmetrically provided with a limit groove 811, which is symmetrically provided with a buckle 812. Correspondingly, a limit block 821 is symmetrically provided on the inner wall of the mesh cover 82. The limit block 821 is slidably connected with the limit groove 811. When the mesh cover 82 is installed, the limit block 821 is aligned with the limit groove 811 to realize the rapid positioning of the mesh cover 82, which is convenient for installation.

[0036] The inner wall of the mesh cover 82 is symmetrically provided with card slots 822, which are engaged with the buckle 812, and a pull groove 823 is provided on the side wall of the mesh cover 82 at the card slot 822. When the mesh cover 82 is installed, the limit block 821 corresponds to the limit slot 811, and then the mesh cover 82 is pushed upward. The side wall of the mesh cover 82 has a certain elasticity and can be deformed, so that the card slot 822 can cooperate with the buckle 812, and then the mesh cover 82 is fixed under the action of the buckle 812. Conversely, insert a finger or other tool into the pull groove 823, pull the side wall of the mesh cover 82 to both sides to deform it, and the card slot 822 is separated from the buckle 812, so that the mesh cover 82 can be removed.

[0037] In addition to the inner protection structure 6, the utility model also provides an outer protection structure 6. When the sealing cover 5 is opened for ventilation, the outer protection structure 8 can prevent debris from the outside of the vehicle body 1 from entering, thereby improving the protection effect. Moreover, the mesh cover 82 in the inner protection structure 8 is snap-fitted with the fixing sleeve 81, and installation and disassembly are very convenient, which is conducive to cleaning the mesh cover 82 and the fan 4 inside it.

[0038] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
