Description

Technical Field

[0001] This invention relates to the field of vehicle frame technology, and in particular to an internal storage type vehicle frame. Background Technology

[0002] With the continuous development of industrial technology, vehicle performance is constantly improving, leading to increasingly higher requirements for reliability, weight, and vehicle space. Existing vehicle frame structures typically use channel steel and single steel pipes welded together. Air pumps and storage tanks need to be fixed to the vehicle body. Depending on the vehicle model, different sizes and numbers of air cylinders need to be installed, requiring a steel frame to secure the cylinder assembly. This presents the following problems:

[0003] 1. The presence of components such as air pumps, air tanks, water tanks, and steel frames occupies a certain amount of the vehicle's internal space, thus increasing the vehicle's space and volume;

[0004] 2. The vehicle uses metal tanks to store gases and liquids, and the presence of these metal tanks increases the overall weight of the vehicle;

[0005] 3. Low impact safety factor of bumpers: When a vehicle is involved in a collision, the metal bumper is the first protective barrier of the vehicle body. A single tubular bumper has low strength and no cushioning effect, so its ability to protect the vehicle body is weak. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide an internal storage vehicle frame. By incorporating an internal bladder within the vehicle frame structure, vehicles can fill with gases or liquids. Simultaneously, the internal bladder functions as a storage container, reducing the overall weight of the vehicle and saving internal space, eliminating the need for additional gas or water storage containers on the vehicle body. Furthermore, the vehicle frame provides support and protection for the internal bladder, increasing its pressure resistance and consequently increasing the gas and liquid storage capacity.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] A bladder-type vehicle body frame includes multiple intermediate beams, with main beams connected to both ends of the intermediate beams and bumpers connected to the ends of the main beams. The intermediate beams and main beams are hollow inside, and bladders are provided on the inner walls. The bladders are filled with automotive gas or liquid to save interior space of the vehicle body.

[0009] As a further implementation, the vehicle frame has a symmetrical structure, with bumpers located at both ends of the main beam.

[0010] As a further implementation, the bumper is enclosed between itself and the main beam, and an inner bladder is also provided inside the bumper.

[0011] As a further implementation, the inner bladder of the bumper is filled with an inert gas at a set pressure to increase the strength of the bumper, and a reinforcing rib connects the main beam and the bumper.

[0012] As a further implementation, multiple intermediate beams are arranged side by side.

[0013] As a further implementation, at least one intermediate beam is connected to the main beam, and the intermediate beam is also connected to the inner bladder inside the main beam.

[0014] As a further implementation, the inner bladder of the intermediate beam is used to fill hazardous gases or liquids.

[0015] As a further implementation, the inner bladder has openings at corresponding positions with the main beam, intermediate beam, and bumper for connecting pipelines.

[0016] As a further implementation, the outer side of the main beam is provided with multiple support frames, and the support frames are provided with mounting holes for mounting vehicle components.

[0017] As a further implementation, the diameter of the main beam is larger than the diameter of the bumper.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. This invention, by setting an inner bladder inside the vehicle body frame structure, allows the vehicle's gases or liquids to be filled inside the vehicle body frame. At the same time, the inner bladder also functions as a storage tank, reducing the total weight of the vehicle body and saving internal space, eliminating the need to add additional containers for gas and water storage on the vehicle body. Meanwhile, the vehicle body frame provides support and protection for the inner bladder, increasing its pressure resistance, and consequently increasing the gas and liquid storage capacity.

[0020] 2. The present invention fills the inner bladder of the bumper with inert gas, which not only increases the strength of the bumper, but also the inert gas with set pressure inside will play a buffering role when the vehicle is involved in a collision, greatly improving the safety factor of the vehicle.

[0021] 3. The main beam, intermediate beam, and bumper of this invention provide support and protection for the inner bladder, allowing the filled gas and liquid to have a certain pressure, thereby increasing the pressure-bearing capacity of the inner bladder and increasing the gas and liquid storage capacity accordingly.

[0032] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0033] Example 1

[0034] In a typical embodiment of the present invention, reference is made to Figures 1-4 As shown, an internal storage type vehicle frame includes multiple intermediate beams 3, which are arranged in parallel, and the two ends of the intermediate beams 3 are connected to the main beams 1, and the two ends of the main beams 1 are connected by bumpers 2.

[0035] like Figure 1 and Figure 2As shown, the vehicle body frame has a symmetrical structure. Bumpers 2 are located at both ends of the main beam 1. Bumpers 2 include a first bumper 2-1 and a second bumper 2-2. The first bumper 2-1 is the front bumper of the vehicle body frame, and the second bumper 2-2 is the rear bumper. Reinforcing ribs 4 connect the ends of the main beam 1 and the bumpers 2, thereby improving the strength of the vehicle body frame. The bumpers 2 and the main beam 1 are enclosed and not connected; the bumpers 2 are welded to the main beam 1.

[0036] like Figure 1 and Figure 4 As shown, the intermediate beam 3 and the main beam 1 are hollow inside. In this embodiment, the main beam 1 is composed of two steel pipes of different diameters, and an inner bladder 6 is provided on the inner wall of the steel pipes of the main beam 1. The inner bladder 6 is a plastic bladder, and it is filled with automotive gas or liquid to save interior space of the vehicle body. It eliminates the need to place the gas cylinder in the gas cylinder mounting bracket 7 and install it on the vehicle frame. The plastic bladder has good elasticity. When automotive gas or liquid is filled into the plastic bladder 6, the bladder 6 expands and its volume increases until it completely fills the space inside the pipe.

[0037] This embodiment features a structure of five parallel intermediate beams 3. The intermediate beams 3 are the same as the main beams, also made of steel pipes. Plastic airbags are arranged inside the steel pipes. The intermediate beams 3 mainly store some dangerous gases and liquids. Since the intermediate beams 3 are inside the vehicle frame, they are not easy to collide with the outside. In the event of a collision, the main beams 1 on the outside provide protection and support for the intermediate beams, resulting in a high structural safety factor.

[0038] It is understandable that at least one intermediate beam 3 is connected to the main beam 1, and the intermediate beam 3 is also connected to the inner bladder 6 inside the main beam 1; or, the intermediate beam 3 is not connected to the main beam 1. Whether the intermediate beam 3 is connected to the main beam 1 can be specifically set according to the needs of the vehicle body frame, so as to facilitate the reasonable filling of vehicle gas or liquid. The inner bladder 6 has openings at corresponding positions on the main beam 1, intermediate beam 3, and bumper 2 for connecting pipelines, so that when the vehicle needs to use gas or liquid, the gas or liquid can be discharged from the inner bladder 6 through the pipeline. The pipeline should be equipped with structures such as solenoid valves.

[0039] like Figure 3 As shown, the outer side of the main beam 1 is provided with multiple support frames 5. The support frames 5 are welded to the main beam. The support frames 5 are plate-shaped structures and have multiple sets of mounting holes for installing other vehicle components with bolts and nuts. Of course, the support frames 5 can also be welded to the intermediate beam 3. The welding position of the support frames 5 can be set according to the specific requirements of the vehicle body frame.

[0040] The diameter of the steel pipe of the main beam 1 is larger than that of the steel pipe of the bumper 2. The bumper 2 uses a small-diameter steel pipe, and a plastic inner bladder is also installed inside the steel pipe. The inner bladder 6 is filled with inert gas at a set pressure to increase the strength of the bumper. In this embodiment, the inner bladder is an airbag structure.

[0041] When the inner bladder 6 inside the bumper 2 is filled with inert gas at a certain pressure, the pressure of the gas cannot be too high and needs to be adjusted according to the structure of the vehicle body. The presence of inert gas at a certain pressure inside the steel tube of the bumper 2 not only increases the strength of the bumper, but also acts as a buffer when the vehicle is involved in a collision, greatly improving the safety factor of the vehicle.

[0042] The inner bladder 6 in this embodiment mainly serves a sealing function, making it difficult for the gas or liquid filled into the steel pipe to leak. The material of the inner bladder 6 has good elasticity, and its material needs to be selected according to the storage medium, taking into account the material's corrosion resistance and resistance to high and low temperatures.

[0043] The main beam 1, intermediate beam 3, and bumper 2 provide support and protection for the inner bladder 6, allowing the filled gas and liquid to have a certain pressure, thereby increasing the pressure-bearing capacity of the inner bladder 6, and the gas and liquid storage capacity also increase accordingly.

[0044] In this embodiment, an inner bladder 6 is installed inside the vehicle body frame structure (main beam 1, intermediate beam 3, bumper 2), allowing the vehicle's gas or liquid to be filled inside the vehicle body frame. At the same time, the inner bladder 6 also functions as a storage tank, reducing the total weight of the vehicle body and saving internal space, eliminating the need to add additional gas or water storage containers to the vehicle body. Meanwhile, the vehicle body frame provides support and protection for the inner bladder 6, increasing its pressure resistance and consequently increasing the gas and liquid storage capacity.

[0045] Using mechanical simulation software, a uniformly distributed load of 500N was applied simultaneously to the middle of two steel pipes of identical dimensions (2000mm length × 160mm outer diameter × 150mm inner diameter) and with fixed constraints (fixed at both ends). The stress conditions inside the steel pipes were compared with those under a pressure of 13000Pa and without pressure. The constraints and applied loads of the circular pipes were analyzed. Figure 6 As shown. Stress comparison line from the top of the circular tube. Figure 7 The simulation shows that applying a certain pressure inside the steel pipe can reduce the maximum stress in the pipe, with the maximum stress point occurring at both ends of the circular pipe. In actual vehicle frames, stress concentration is prone to occur at the fixed points at both ends of the beams. This simulation analysis strongly demonstrates that filling the steel pipe with gas at a certain pressure can increase the strength of the steel pipe, thereby increasing the reliability and safety of the vehicle frame.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
