Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted oxygen generators, and more particularly to a vehicle-mounted oxygen generator. Background Technology

[0002] In-vehicle oxygen concentrators have significant application value in vehicle driving scenarios. They can continuously provide a stable oxygen supply for drivers and passengers, especially suitable for high-altitude hypoxic environments or long-distance driving. They can effectively alleviate discomfort such as fatigue and dizziness caused by insufficient oxygen, improving driving comfort and safety. At the same time, for individuals with respiratory diseases, in-vehicle oxygen concentrators can ensure air quality inside the vehicle, meeting their health needs and serving as an important auxiliary device for improving driving safety in special environments.

[0003] However, traditional in-vehicle oxygen concentrators have significant drawbacks in terms of installation stability. Due to the lack of a dedicated fixing structure for vehicle driving characteristics, these devices can usually only be simply placed in the seat or storage space. When the vehicle starts, stops, turns, or travels on bumpy roads, the oxygen concentrator is prone to violent shaking or even tipping over due to inertia, which not only affects the oxygen production efficiency and equipment lifespan, but may also cause collision injuries to the occupants due to equipment displacement. Utility Model Content

A fixing component is provided at the end of the positioning rod away from the connecting shaft for positioning the oxygen concentrator body on the vehicle's center console armrest box.

[0007] Preferably, the fixing component includes two positioning pieces slidably installed in the positioning rod groove and a driving component for pushing the two positioning pieces to move synchronously. Limiting blocks are fixed on the upper and lower sides of the two positioning pieces, the limiting blocks are in contact with the inner wall of the positioning rod, and a spring is fixedly connected between the two positioning pieces.

[0008] Preferably, the driving component includes a push rod slidably installed in the positioning rod and a screw rod rotatably installed in the positioning rod. One end of the screw rod is located outside the positioning rod, and the other end of the screw rod is threadedly connected to the push rod. A push block is fixedly provided inside the positioning plate, and the inclined surface of the end of the push rod is in contact with the inclined surface of the end of the push block.

[0009] Preferably, the positioning rod is provided with a support assembly, the support assembly includes an outer rod rotatably mounted on the positioning rod, an inner rod slidably disposed inside the outer rod, a positioning shaft with an I-shaped cross-section inserted into a groove at the end of the inner rod, and a bolt threaded on the outer rod, the end of the bolt being in contact with the outer wall of the inner rod.

[0010] Preferably, a concave first locking block is fixed on the inner side of the positioning rod, and the end of the inner rod is in contact with the inner wall of the first locking block.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0025] Example: This example provides a vehicle-mounted oxygen generator. See [link / reference]. Figure 1-6 Specifically, it includes an oxygen concentrator body 1, a base plate 11 fixedly installed at the bottom of the outer shell of the oxygen concentrator body 1, a connecting shaft 13 fixedly installed at one end of the base plate 11, and L-shaped positioning rods 12 rotatably connected to both ends of the connecting shaft 13. The end of the positioning rod 12 away from the connecting shaft 13 is provided with a fixing component 2 for positioning the oxygen concentrator body 1 on the vehicle's central control armrest box.

[0026] In this embodiment, a base plate 11 with the same volume as the oxygen concentrator body 1 is added to the bottom of the oxygen concentrator body 1. Two positioning rods 12 are connected to both sides of the base plate 11 via connecting shafts 13. By placing the oxygen concentrator body 1 on the center console armrest box inside the vehicle, the two positioning rods 12 are rotated so that they are positioned in the gap between the center console armrest box and the seat. The positioning rods 12 are fixed in the gap between the center console armrest box and the seat by the fixing assembly 2, thus positioning the oxygen concentrator body 1 on the center console armrest box and improving the stability of the oxygen concentrator body 1. Since the center console armrest box is located in the center of the vehicle, it is convenient for people in different positions inside the vehicle to use the oxygen concentrator body 1. Moreover, the positioning rods 12 and the base plate 11 are rotatably connected. When it is necessary to open the center console armrest box, the oxygen concentrator body 1 can be rotated to move away from the upper surface of the center console armrest box, such as ( Figure 3 ).

[0027] In the specific implementation process, such as Figure 4 and Figure 5 As shown, the fixing component 2 includes two positioning pieces 21 that are slidably installed in the groove of the positioning rod 12 and a driving component for pushing the two positioning pieces 21 to move synchronously. Limiting blocks 22 are fixedly provided on the upper and lower sides of the two positioning pieces 21. The limiting blocks 22 are in contact with the inner wall of the positioning rod 12. A spring 23 is fixedly connected between the two positioning pieces 21.

[0028] In this embodiment, the driving component drives two positioning plates 21 to move synchronously outwards towards the positioning rod 12. The two positioning plates 21 respectively mate with the side of the center console armrest and the side of the seat. The friction generated between the positioning plates 21 and the side of the center console armrest and the side of the seat fixes the position of the positioning rod 12. When the driving component moves in the opposite direction, the spring 23 pulls the two positioning plates 21 to quickly return to their original position. The limiting block 22 on the positioning plate 21 mates with the inner wall of the groove of the positioning rod 12 to limit the movement direction of the positioning plate 21.

[0029] In the specific implementation process, such as Figure 4 and Figure 5 As shown, the driving component includes a push rod 3 slidably installed in the positioning rod 12 and a screw 31 rotatably installed in the positioning rod 12. One end of the screw 31 is located outside the positioning rod 12, and the other end of the screw 31 is threadedly connected to the push rod 3. A push block 32 is fixedly provided on the inner side of the positioning plate 21, and the inclined surface at the end of the push rod 3 is in contact with the inclined surface at the end of the push block 32.

[0030] In this embodiment, a rotating ring is provided on the part of the screw 31 located outside the positioning rod 12 to facilitate driving the screw 31. By rotating the screw 31, the push rod 3 moves laterally along the groove of the positioning rod 12. The end of the positioning rod 12 is triangular, and the end of the triangle will enter the two push blocks 32, pushing the two push blocks 32 outward. The push blocks 32 then drive the positioning piece 21 to move outward, thereby achieving synchronous driving of the positioning piece 21.

[0031] In the specific implementation process, such as Figure 3 and Figure 6 As shown, the positioning rod 12 is provided with a support assembly 4. The support assembly 4 includes an outer rod 41 rotatably mounted on the positioning rod 12, an inner rod 42 slidably provided inside the outer rod 41, a positioning shaft 43 with an I-shaped cross section inserted into the groove at the end of the inner rod 42, and a bolt 44 threaded on the outer rod 41, the end of the bolt 44 being in contact with the outer wall of the inner rod 42.

[0032] In this embodiment, when the central control armrest box needs to be used, the oxygen concentrator body 1 can be rotated, such as ( Figure 3 Next, rotate the outer rod 41 to adjust its position. Then, pull the inner rod 42 so that the positioning shaft 43 at the end of the inner rod 42 is engaged in the groove at the bottom of the base plate 11, thereby supporting the oxygen concentrator body 1 and keeping it tilted for easy access to the central control armrest box. The inner rod 42 is in contact with the inner wall of the outer rod 41 and can slide along the outer rod 41. The inner rod 42 is fixed by the compression of the end of the bolt 44 against the outer wall. The positioning shaft 43 can move along the groove at the end of the inner rod 42, allowing a part of the positioning shaft 43 to leave the groove of the inner rod 42 and engage in the groove at the bottom of the base plate 11 for connecting the base plate 11.

[0033] In the specific implementation process, such as Figure 1 and Figure 3 As shown, a concave first locking block 5 is fixedly provided on the inner side of the positioning rod 12, and the end of the inner rod 42 is in contact with the inner wall of the first locking block 5.

[0034] In this embodiment, the first locking block 5 is made of elastic plastic. When the support component 4 is not in use, the inner rod 42 is inserted into the first locking block 5. The position of the support component 4 is fixed by the friction between the first locking block 5 and the outer wall of the inner rod 42, thereby realizing the storage of the support component 4.

[0035] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3 As shown, L-shaped second locking blocks 6 are fixed on both sides of the outer wall of the oxygen generator body 1, and the inner side of the second locking block 6 is in contact with the outer wall of the positioning rod 12.

[0036] In this embodiment, the second locking block 6 is made of elastic plastic. When the positioning rod 12 is not in use, the end of the positioning rod 12 is locked in the second locking block 6. The position of the positioning rod 12 is fixed in the same way as the first locking block 5, so as to realize the storage of the positioning rod 12.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
