Description

Technical Field

[0001] This utility model relates to the technical field of vehicle-mounted oxygen generator equipment, specifically an installation device for a vehicle-mounted oxygen generator. Background Technology

[0002] In low-oxygen environments such as high-altitude areas, low air pressure and low oxygen partial pressure can easily lead to acute mountain sickness symptoms (such as dizziness, headache, and nausea), especially at altitudes above 5000 meters. Physical and mental work capacity decreases significantly, necessitating supplemental oxygen to ensure personnel safety. Oxygen generators, using lithium molecular sieves as adsorbents and based on the pressure swing adsorption principle, produce high-purity oxygen (concentrations reaching 90%–96%), making them crucial equipment for coping with low-oxygen environments.

[0003] Currently, small oxygen concentrators are mostly used in fixed settings such as homes and offices, and have significant limitations in the vehicle field. Existing vehicle oxygen concentrators lack a dedicated fixing structure for vehicle scenarios. The main body of the oxygen concentrator and the oxygen output components are prone to shaking and displacement when the vehicle is in motion, especially on bumpy roads, which affects the stability and safety of the equipment. Therefore, we need to provide an installation device for vehicle oxygen concentrators. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: an installation device for a vehicle-mounted oxygen generator, comprising:

[0025] The system includes an oxygen generator 1, an oxygen outlet box 2, an oxygen supply pipe 3, and an installation mechanism 4. Each of the multiple oxygen outlet boxes 2 has an oxygen supply pipe 3 installed on one side. One end of each of the multiple oxygen supply pipes 3 is connected to the oxygen generator 1. The installation mechanism 4 includes a stabilizing component 41 and a fixing component 42. The oxygen generator 1 is installed in the trunk of the vehicle via the stabilizing component 41, and the oxygen outlet boxes 2 are installed on the back of the driver and passenger seats via the fixing component 42.

[0026] The oxygen concentrator 1 includes a housing 11, an air inlet louver 12, an air outlet louver 13, and a power input port 14. The housing 11 has an air inlet louver 12 and an air outlet louver 13 on its surface, and the power input port 14 is installed on the surface of the housing 11.

[0027] Specifically, the oxygen concentrator 1 can be fixed in the vehicle trunk using the stabilizing component 41 in the mounting mechanism 4. The oxygen outlet box 2 is fixed behind the driver and passenger seats using the fixing component 42, facilitating the fixation of the oxygen concentrator 1 and the oxygen outlet box 2. The stabilizing component 41, through the cooperation of the support plate 411, mounting rail 412, and support bracket 413, combined with 3M adhesive 6 and Velcro, can firmly fix the oxygen concentrator 1 in the trunk, preventing displacement or tipping during vehicle bumps or sudden braking, and reducing the risk of damage to the equipment. Damage to components caused by vibration; the fastener 42, with the clamping structure of the double threaded rod 422 and the clamping seat 423, can stably fix the oxygen box 2 behind the driver and passenger seats, preventing the oxygen box 2 from shaking and falling off, ensuring safe use. The oxygen generator 1 is fixed in the trunk without occupying the passenger space in the vehicle. The oxygen box 2 is set close to the occupants, making it convenient for users to take oxygen nearby, without affecting driving operation and activities in the vehicle. At the same time, the installation method of the fixing structure is flexible and adaptable to different models, improving the practicality in the vehicle scenario.

[0028] Air intake louvers 12 and exhaust louvers 13 are respectively located on opposite side walls of the body 11. A dustproof mesh is fixed to the inside of the air intake louvers 12 via clips, while an electromagnetic shielding copper mesh is fixed to the inside of the exhaust louvers 13 via bolts. The edges of the electromagnetic shielding copper mesh are welded to the side walls of the body 11 to form electrical continuity. The power input port 14 is a waterproof aviation plug, sealed to the mounting holes on the surface of the body 11 with a silicone sealing ring. The power input port 14 is electrically connected to the control board inside the chassis via a wire. The separate placement of the air intake and exhaust louvers 13 on both sides enables air convection, improving heat dissipation efficiency. The dustproof mesh prevents dust from entering, and the electromagnetic shielding copper mesh is welded to the body 11 to ensure shielding effectiveness, solving the problem of electromagnetic interference leakage in the vehicle environment. The waterproof aviation plug, combined with a silicone sealing ring, prevents rainwater or condensation from seeping in, making it suitable for humid vehicle environments.

[0029] The stabilizing component 41 includes a support plate 411, a mounting rail 412, and a support corner bracket 413. The mounting rail 412 is slidably mounted on both sides of the surface of the support plate 411. Both mounting rails 412 are fixed to the surface of the body 11. Two support corner brackets 413 are fixedly mounted on the surface of the support plate 411. The surface of the support corner bracket 413 is in contact with the mounting rail 412.

[0030] Furthermore, the mounting rail 412 has a U-shaped groove structure with its opening facing the support plate 411, and the groove is coated with a polytetrafluoroethylene lubricating layer. The support plate 411 is made of galvanized steel sheet bent into shape, and its surface slides in fit with the U-shaped groove of the mounting rail 412. The bottom of the support plate 411 has a 90° bent edge that matches the corner of the trunk. The support corner bracket 413 is made of aluminum alloy and is welded and fixed to the support plate 411. The side of the support corner bracket 413 away from the support plate 411 has an arc-shaped surface that fits against the outer wall of the mounting rail 412. The U-shaped groove guide rail, combined with the polytetrafluoroethylene coating, enables the support plate 411 to slide smoothly, making it easy to adjust the fixed position according to the trunk space. The galvanized steel sheet support plate 411 has both strength and corrosion resistance. The 90° bent edge matches the corner of the trunk, and the arc-shaped surface of the support corner bracket 413 fits against the guide rail, enhancing the support stability of the body 11 and solving the problem of the body 11 shaking when the vehicle is bumpy.

[0031] The bottom of the support bracket 413 is provided with two 3M adhesive 6, and the surface is integrally machined with a pry block 5;

[0032] It is worth noting that 3M Adhesive 6 is an acrylic pressure-sensitive adhesive with a thickness of 0.8-1.2mm. One side is bonded to the bottom of the support bracket 413 with butyl adhesive, and the other side is covered with release paper. The lever 5 is made of ABS plastic and is injection molded integrally with the support bracket 413. The surface of the lever 5 has anti-slip texture. The high-strength 3M Adhesive 6 is adapted to vehicle temperature changes (-40℃ to 80℃) to ensure that the support bracket 413 is firmly bonded to the bottom of the trunk. The ABS lever 5 facilitates manual adjustment of the position of the support plate 411, and the anti-slip texture improves the ease of operation, solving the problem of cumbersome installation / disassembly of traditional fixing methods.

[0033] The fastener 42 includes a groove 421, a double threaded rod 422 and a clamping seat 423. The groove 421 is opened on the back of the oxygen box 2. The double threaded rod 422 is rotatably installed inside. The clamping seats 423 are threaded on both sides of the surface of the double threaded rod 422. The two clamping seats 423 are provided on adjacent sides. The grooves abut against the metal rod at the bottom of the seat headrest.

[0034] It should be noted that the threads at both ends of the double-threaded rod 422 are in opposite directions, and its connection with the groove 421 is rotatably connected by a deep groove ball bearing, with the outer ring of the bearing having an interference fit with the groove 421. The clamping seat 423 is made of nylon, and its bottom is provided with a guide block that slides with the bottom surface of the groove 421. The inner wall of the groove is bonded to the arc-shaped cotton 7 with hot melt adhesive. The reverse thread design allows the two clamping seats 423 to move closer / away synchronously when the double-threaded rod 422 rotates, improving adjustment efficiency. The deep groove ball bearing reduces rotational friction, and the guide block prevents the clamping seat 423 from shifting. The nylon clamping seat 423 has both toughness and wear resistance, avoiding scratches on the headrest metal rod and solving the problem of the fixing part 42 getting stuck and damaging the seat. A partition is fixedly installed inside the groove 421, located on one side of the double-threaded rod 422, to protect the double-threaded rod 422, and the clamping seat 423 is slidably installed inside the partition surface.

[0035] The groove is equipped with an arc-shaped cotton 7, and one end of the double threaded rod 422 passes through the surface of the oxygen box 2 and is equipped with an adjustment part;

[0036] Among them, the arc-shaped cotton 7 is a high-density polyurethane sponge with a density of 30-40 kg / m³, and its surface is covered with a polyester-cotton blended fabric; the adjustment part is a butterfly knob made of PVC material, which is connected to the double threaded rod 422 by a flat key, and the surface of the knob is provided with anti-slip protrusions. The high-density sponge arc-shaped cotton 7 buffers the clamping force and prevents the metal rod from being deformed by pressure. The polyester-cotton covering layer improves wear resistance; the butterfly knob is easy to turn by hand, and the anti-slip protrusions increase friction, solving the problem of the convenience of manually adjusting the fixing part 42 in the vehicle scenario.

[0037] The bottom corners of the compartment 11 are evenly distributed with rubber pads 8;

[0038] The rubber pad 8 is made of nitrile rubber with a Shore hardness of 60-70A. It is integrally connected to the bottom of the compartment 11 by molding. The bottom of the rubber pad 8 has a grid-like anti-slip texture, and the height difference of the four rubber pads 8 does not exceed 0.2mm. Nitrile rubber has both elasticity and oil resistance, making it suitable for the oily environment of the trunk. The grid texture enhances friction, and the height difference control ensures that the compartment 11 is placed stably, reducing the transmission of vibration when the vehicle is in motion and protecting precision components such as molecular sieve components inside the chassis.

[0039] One side of the compartment 11 is attached to the inner wall of the vehicle's trunk using Velcro fasteners;

[0040] The Velcro fastener consists of a hook side and an adhesive side. The hook side is made of nylon 66 and is attached to the side wall of the compartment 11 with epoxy resin adhesive. The hook side is made of polyester and is attached to the inner wall of the trunk with automotive double-sided tape. The peel strength of the Velcro fastener is ≥5N / cm, and the width is 5-8cm. The high peel strength Velcro fastener combined with the wide design helps to fix the compartment 11 and forms a double fixation with the fastener 41. The nylon hook side and the polyester adhesive side have strong weather resistance and can adapt to the high temperature and sun exposure environment of the vehicle, solving the problem of loosening under extreme road conditions with a single fixing method.

[0041] The oxygen generator 1 and oxygen outlet box 2 involved in this application are both implemented using existing mature technologies and are connected to an external PLC controller and power supply. This is a conventional technical means in this field, so the specific circuit connection, control logic and working process will not be described in detail.

[0042] All threaded mounting surfaces in this application utilize a modified triangular thread with a self-locking function. The thread helix angle is designed to be 1.5°-2.5° to enhance the anti-loosening effect. After phosphating, the thread surface is coated with an 8-12μm Dacromet coating and impregnated with silicone sealant to form a sealing layer, resulting in excellent corrosion resistance. In addition, the thread can effectively expel dust, and it can still be used normally even if a small amount of dust adheres to it.

[0043] The device's chassis houses molecular sieve components, an air compressor, and a control board. The chassis also includes an air inlet, air outlet, power input interface, control interface, and oxygen output port. Electromagnetic shielding meshes are installed at the air inlet and outlet to effectively reduce electromagnetic interference signal leakage. The oxygen generator 1 employs a distributed, multi-point control layout. The control box has a built-in oxygen terminal and can adjust oxygen concentration and flow rate as required. It uses microcomputer control, is adaptable to various vehicle power supplies, and has a wide voltage input adaptability, operating normally with vehicle power supplies ranging from 19V to 32V. The vehicle-mounted oxygen generator 1 uses a distributed control system, allowing users to adjust oxygen flow rate and concentration according to their needs via the oxygen generator control box. A shielded copper mesh is installed at the air inlet and outlet to ensure effective connection between the copper mesh and the housing 11, providing electrical continuity and effectively shielding internal electromagnetic signals from interference with the outside. Air passes through a filter and enters the air compressor, which compresses the air to 0.2 MPa. The air then enters the molecular sieve tower, which produces 93% high-concentration oxygen. The oxygen enters the oxygen tank and, through an automatic flow control valve, enters the mixing tank at a specific flow rate. A portion of the air from the air compressor is mixed with the air at the required flow rate and enters the mixing tank. The mixing tank is equipped with an oxygen concentration sensor, and the controller controls the oxygen and air flow control valves to control the mixing ratio and obtain the required oxygen concentration gas for external supply. Terminal flow control is achieved using a rotor flow meter or a humidification bottle.

[0044] The box body 11 is placed at the corner of the vehicle's trunk. Since the Velcro is located on one side of the box body 11, the hook side of the Velcro is fixed to one side of the box body 11, and the adhesive side of the Velcro is installed on the inner wall of the trunk, which provides auxiliary fixation for the box body 11. The support plate 411 is slid on the two mounting rails 412, and the support plate 411 moves down. The 3M adhesive 6 at the bottom of the support plate 411 is pasted into the trunk, thus fixing the box body 11 at the corner of the trunk. The support plate 411 has a support corner seat 413 at the bend to enhance the support. The surface of the box body 11 has three oxygen supply pipes 3, which are connected to three oxygen outlet boxes 2. The oxygen outlet boxes 2 are installed on the back of the driver and passenger seats through the fastener 42. Specifically, rotating the adjustment part drives the double threaded rod 422 to rotate, so that the two clamping seats 423 move closer to each other. The groove on one side of the clamping seat 423 abuts against the metal rod at the bottom of the seat headrest, thus fixing the oxygen outlet box 2.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
