[0002] With the continuous development of social economy, cars have slowly changed our lifestyle. More and more people are traveling on holidays, no longer in simple tour groups, but traveling freely. As a result, RVs are chosen by more and more camping enthusiasts to meet their needs. Because camping enthusiasts often appear in places with relatively poor road conditions, it is particularly important to choose a suitable chassis structure and RV chassis plus frame structure.

[0003] After searching, a motorhome chassis frame and motorhome (authorization announcement number: CN 207374215U) "comprises a chassis support frame. A storage compartment frame is located in the length direction of the chassis support frame; wherein the storage compartment frame is connected to the two support columns of the chassis support frame through two connecting parts; the chassis frame of the motorhome provides sufficient chassis support for the furniture and supplies in the motorhome, and is also equipped with a storage compartment frame, which is convenient for placing items when traveling."

[0004] Based on the above-mentioned related technologies, the applicant believes that the above-mentioned technologies lack a shock-absorbing mechanism. When the RV encounters poor road conditions during its travel, bumps will occur. The lack of a shock-absorbing mechanism will affect the cabinets and sofas inside the RV, and may even cause damage over a long period of time. To address the above problems, we have launched an RV chassis frame. Utility Model Content

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0023] Reference Figure 1 - Figure 5A RV chassis frame comprises a chassis frame 1, a supporting frame 2 is provided on the top of the chassis frame 1, elastic grooves 3 are symmetrically opened on both sides of the top of the chassis frame 1, a buffer mechanism 4 is provided on the top of the chassis frame 1, the buffer mechanism 4 comprises four No. 1 buffer components and four No. 2 buffer components, the No. 1 buffer components and the No. 2 buffer components are used in conjunction with each other, the No. 1 buffer component comprises a sliding column 401, the sliding column 401 is fixedly connected to the inside of the elastic groove 3, a transverse spring 402 is sleeved on the outer side of the sliding column 401, a sliding block 403 is slidably connected to the outer side of the sliding column 401, a rotating block 404 is fixedly connected to the top of the sliding block 403, and a diagonal support rod 405 is rotatably connected to the top of the rotating block 404, and a connecting block 406 is fixedly connected to the bottom of the supporting bracket 2, and the connecting block 406 is rotatably connected to the other end of the diagonal support rod 405. The second buffer assembly includes a connecting column 409, which is slidably connected to the inside of the chassis frame 1, and a longitudinal spring 407 is sleeved on the outside of the connecting column 409. The bottom of the connecting column 409 is fixedly connected to a limit plate 408. The first buffer assembly and the second buffer assembly cooperate with each other. The top of the chassis frame 1 is symmetrically provided with fixing grooves 5, and the insides of the two fixing grooves 5 are fixedly connected with damping columns 6, and the tops of the two damping columns 6 are fixedly connected to the bottom of the support frame 2.

[0024] In the above technical solution, it is considered that when the RV is moving and encounters poor road conditions, it will be bumpy and lack of shock-absorbing mechanism, which will affect the cabinets and sofas inside the RV, and even cause damage for a long time. In order to solve this problem, the specific operations are as follows:

[0025] Reference Figure 1 - Figure 5 In a preferred embodiment, when the RV encounters bumps and vibrations, the cabin of the RV presses the connecting block 406 downward, and the connecting block 406 moves downward to squeeze the diagonal support rod 405. Under the push of the diagonal support rod 405, the sliding block 403 slides on the outside of the sliding column 401, so that the transverse spring 402 is squeezed and compressed. At the same time, the supporting bracket 2 presses the connecting column 409 downward, and the connecting column 409 slides downward, so that the longitudinal spring 407 is compressed. Under the tension of the transverse spring 402 and the longitudinal spring 407, the vibration encountered by the cabin of the RV can be filtered and buffered to avoid direct vibration of the cabin of the RV. Through the set damping column 6, the transverse spring 402 and the longitudinal spring 407 can quickly restore their shape after vibration to avoid repeated vibration. Through the set buffer mechanism 4, the vibration and bumps encountered by the RV can be effectively filtered and buffered to avoid long-term direct vibration causing damage to the internal components of the RV, thereby extending the service life and riding comfort of the RV. The structure is simple and the practicability is strong.

[0026] Reference Figure 1 - Figure 5In a preferred embodiment, the interior of the chassis frame 1 is symmetrically fixedly connected with reinforcing ribs 7 in an X shape, and the interior of the chassis frame 1 is fixedly connected with cross bars 8, and the reinforcing ribs 7 and cross bars 8 are used in conjunction with each other. Weight-reducing grooves 9 are symmetrically provided on both sides of the chassis frame 1, and mounting plates 10 are symmetrically fixedly connected on both sides of the bottom of the chassis frame 1, and mounting holes 11 are provided inside the mounting plates 10. A rubber pad 12 is fixedly connected to the top of the support bracket 2. The strength of the chassis frame 1 can be increased and the service life can be extended by the provided reinforcing ribs 7 and cross bars 8, the weight of the chassis frame 1 can be reduced by the provided weight-reducing grooves 9, and the support bracket 2 and the RV cabin can be buffered by the provided rubber pads 12 to avoid direct friction.

[0027] Working principle: In actual use, the staff first installs the chassis frame 1 on the bottom of the RV, connects the supporting bracket 2 to the bottom of the RV, and then installs other components. After the installation is completed, when the RV encounters bumps and vibrations, the cabin of the RV presses down the connecting block 406, and the connecting block 406 moves downward to squeeze the diagonal support rod 405. Under the push of the diagonal support rod 405, the sliding block 403 slides on the outside of the sliding column 401, so that the transverse spring 402 is squeezed and compressed. At the same time, the supporting bracket 2 presses down the connecting column 409, and the connecting column 409 slides downward, so that the longitudinal spring 407 is compressed. Under the tension of the transverse spring 402 and the longitudinal spring 407, the vibration encountered by the cabin of the RV can be filtered and buffered to avoid direct vibration of the RV cabin. Through the set damping column 6, the transverse spring 402 and the longitudinal spring 407 can quickly restore their shape after vibration to avoid repeated vibration. At this point, the staff has completed the installation and shock absorption of the RV chassis.

[0028] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
