Description

Technical Field

[0001] The utility model relates to the technical field of oxygen generation modules, in particular to a multi-tower oxygen generation module. Background Art

[0002] An in-vehicle oxygen generation module is a device that can generate and supply oxygen inside a vehicle. The in-vehicle oxygen generator adopts switched-mode inverter power supply technology to convert the 12V or 24V DC power supply of the vehicle into 220V AC power supply, so as to meet the power supply requirements of the oxygen generator. The structure of the in-vehicle oxygen generation module includes a switched-mode inverter power supply and a pressure swing adsorption oxygen generation device. Among them, the two molecular sieve adsorption towers in the oxygen generation device are the main devices, with a compact design and high integration.

[0003] Inside the in-vehicle oxygen generation module, after the air is compressed by an air compressor, it passes through drying and dust removal, and then enters the left adsorption tank through the left suction inlet valve. The pressure in the tank rises, and the nitrogen molecules in the compressed air are adsorbed by the molecular sieve. The unadsorbed oxygen passes through the adsorption bed, and enters the oxygen storage tank through the left suction outlet valve and the oxygen production valve. This process is called left suction. The duration is 50 - 60 seconds. After the left suction process ends, the left adsorption tank and the right adsorption tank are connected through the upper and lower pressure equalizing valves to make the pressures of the left and right adsorption tanks balanced. This process is called pressure equalization, and the duration is 8 seconds. Among them, multiple left adsorption tanks and multiple right adsorption tanks form the entire oxygen generation module. Currently, when installing the oxygen generation module, it is generally directly installed on the guide rail through bolts. In this way, when the vehicle is driving, if there is an emergency brake, under the action of gravity, the bolts will become loose. Therefore, a new type of multi-tower oxygen generation module is needed to solve the above problems. Summary of the Utility Model

A plurality of sliders are fixedly installed on the surface of the moving plate, and a plurality of limiting blocks are slidably sleeved on the surfaces of the plurality of sliders. A force application mechanism and a limiting mechanism are further included. The force application mechanism is used to limit the positions of the plurality of sliders inside the inner walls of the plurality of limiting blocks respectively and apply a force to keep the plurality of sliders in place, and the limiting mechanism is used to install the plurality of limiting blocks above the bottom plate respectively.

[0006] Further, the installation mechanism includes a plurality of mounting plates fixedly installed on the bottom plate of the oxygen generation module.

Specific embodiments

[0018] For the purposes of making the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0019] This application provides a multi-tower oxygen generation module, which is mainly used to solve the problem that inside the on-vehicle oxygen generation module, after the air is compressed by an air compressor, passes through drying and dust removal, and then enters the left adsorption tank through the left suction inlet valve, the pressure in the tank rises, the nitrogen molecules in the compressed air are adsorbed by the molecular sieve, the unadsorbed oxygen passes through the adsorption bed, and enters the oxygen storage tank through the left suction outlet valve and the oxygen production valve. This process is called left suction. The duration is 50 - 60 seconds. After the left suction process ends, the left adsorption tank and the right adsorption tank are connected through the upper and lower pressure equalizing valves to make the pressures of the left and right adsorption tanks balanced. This process is called pressure equalization, and the duration is 8 seconds. Among them, multiple left adsorption tanks and multiple right adsorption tanks form the entire oxygen generation module. Currently, when installing the oxygen generation module, it is generally directly installed on the guide rail through bolts. In this way, when the vehicle is driving, if there is an emergency brake, under the action of gravity, the bolts will become loose, and the following technical solutions are provided. The following will be combined with Figures 1-4 make a detailed description:

[0020] A multi-tower oxygen generation module, comprising: a bottom plate 1 with several mounting bolts 2 threadedly inserted on its surface. Above the bottom plate 1, a moving plate 3 is provided, and above the moving plate 3, an oxygen generation module 4 is provided. The user can install the oxygen generation module 4 on the top of the moving plate 3 through a mounting mechanism 5. At the same time, several sliders 6 are fixedly installed on the surface of the moving plate 3, and several limit blocks 7 are slidably sleeved on the surfaces of the several sliders 6. The user can install the several limit blocks 7 above the bottom plate 1 through a limiting mechanism 9. At this time, under the action of a force application mechanism 8, the positions of the several sliders 6 are limited within the inner walls of the several limit blocks 7 and all are subjected to forces to maintain their original positions. The main components of the mounting mechanism 5 are: several fixing bolts 502, and several mounting plates 501 are fixedly installed at the bottom of the oxygen generation module 4. After the user fits the several mounting plates 501 on the surface of the moving plate 3, and then threadedly inserts the several fixing bolts 502 into the surfaces of the several mounting plates 501 and then threadedly inserts them into the surface of the moving plate 3, the installation of the oxygen generation module 4 above the moving plate 3 can be realized. The main components of the force application mechanism 8 are: several springs 802. Two insertion rods 801 are fixedly installed on the surfaces of the several sliders 6, and the several insertion rods 801 are respectively slidably inserted into the inner walls of the several limit blocks 7. One ends of the several springs 802 are respectively fixedly installed on the surfaces of the limit blocks 7, and the other ends of the several springs 802 are respectively fixedly installed on the surfaces of the several limit blocks 7 and the several sliders 6. In this way, when the slider 6 slides within the inner wall of the limit block 7, it will drive the insertion rod 801 to move, realizing the stretching or compression of the spring 802, thereby applying a force to the slider 6 to bounce back to its original position. The main components of the limiting mechanism 9 are: several limiting bolts 902. Several limiting grooves 901 are opened at the top of the bottom. After the user slidably inserts the several limit blocks 7 into the inner walls of the several limiting grooves 901 respectively, and then threadedly inserts the several limiting bolts 902 into the tops of the several limit blocks 7 and then abuts against the inner walls of the several limiting grooves 901, the limitation of the several limit blocks 7 above the bottom plate 1 can be realized.

[0021] During use, the user can install the bottom plate 1 in the vehicle through several mounting bolts 2, then install the oxygen generation module 4 on the top of the moving plate 3 through the mounting mechanism 5, and limit the positions of the several limit blocks 7 above the bottom plate 1 through the limiting mechanism 9. In this way, during the subsequent driving of the vehicle, even if it suddenly stops, under the action of gravity, the oxygen generation module 4 moves, driving the several sliders 6 to slide within the inner walls of the several limit blocks 7. Under the action of the force application mechanism 8, the several sliders 6 will also be subjected to forces to return to their original positions, thereby avoiding the loosening of the mounting mechanism 5 and the resulting situation of the oxygen generation module 4 falling off, fully reflecting the practicality of the device.

[0022] Such as Figure 4As shown, in some embodiments, in order to further optimize the solution, a number of slots 11 are opened at the top of the bottom plate 1, and two insertion plates 10 are fixedly installed at the bottom of each of the number of limit blocks 7. During installation, the user slides each of the number of insertion plates 10 into the inner walls of the number of slots 11 respectively, so as to further limit the limit blocks 7. Protrusions 13 are provided on the surfaces of each of the number of sliders 6, and accommodation grooves 12 are opened on the inner walls of each of the number of limit blocks 7. Each of the number of protrusions 13 is slidably inserted into the inner walls of each of the number of accommodation grooves 12. In this way, when each of the number of sliders 6 shakes, each of the number of protrusions 13 will slide on the inner walls of each of the number of accommodation grooves 12, controlling the shaking range of each of the number of sliders 6 inside each of the number of limit blocks 7.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
