Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted oxygen generator technology, specifically a vehicle-mounted oxygen generator compressor body connection bracket. Background Technology

[0002] With the rise of high-altitude self-driving tourism in recent years, the demand for in-car oxygen concentrators in high-altitude areas such as Tibet and Yunnan has become increasingly strong. Population aging and health concerns have also driven the widespread adoption of in-car oxygen concentrators. As vehicle comfort improves, automakers are imposing increasingly stringent requirements and tests on vehicle NVH (noise, vibration, and harshness). At the same time, the increasing application scenarios for in-car oxygen concentrators and the diversified needs of users have made the NVH performance of oxygen concentrators crucial to the experience of drivers and passengers, as vibration issues during operation can directly affect comfort.

[0003] Existing oxygen generator systems generally consist of two main subsystems: a compressor air supply system and a molecular sieve oxygen generation system. The compressor air supply system is the biggest source of vibration in the oxygen generation system and must be eliminated. The compressor air supply system also includes the compressor body and the matching cooling fan. How to integrate, install, support, and reduce vibration of the compressor body and cooling fan is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This utility model provides a vehicle-mounted oxygen generator compressor body connection bracket, which can solve the problems of complex installation structure, poor shock absorption effect, and inability to effectively integrate the compressor body and cooling fan in existing oxygen generator compressor air source systems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted oxygen concentrator compressor body connection bracket, comprising a main connection bracket for connecting to the compressor and a secondary connection bracket for connecting to a fan, wherein the main connection bracket is arranged horizontally, the secondary connection bracket is arranged vertically, one side of the main connection bracket is connected to the secondary connection bracket, the side of the main connection bracket is provided with an outwardly extending first connection arm and a second connection arm, and the sides of the main connection bracket and the secondary connection bracket opposite to the first connection arm are respectively provided with an outwardly extending third connection arm and a second connection arm. The four connecting arms, including the first, second, third, and fourth connecting arms, are all equipped with shock-absorbing connecting components for connecting to the vehicle body. The lower side of the secondary connecting bracket includes a transverse support plate for installing a drainer. By setting the main and secondary connecting brackets, the compressor and fan can be integrated together for shock-absorbing installation. The suspended installation of the four shock-absorbing connecting components can greatly reduce the vibration of the compressor and fan during operation. Furthermore, by setting the transverse support plate to install the drainer, the airflow output by the compressor during operation can be drained in a timely manner without the need for a separate mounting bracket to install the drainer.

[0006] Preferably, both the main connecting bracket and the auxiliary connecting bracket are frame-type structures, and each of the main connecting bracket and the auxiliary connecting bracket has a hollow part that matches the shape of the compressor and the fan. This allows the main connecting bracket and the auxiliary connecting bracket to fit tightly against the outer surface of the compressor and the fan, reducing the weight of the main connecting bracket and the auxiliary connecting bracket and reducing the volume of the entire installation module.

[0007] Preferably, the roots of the first and second connecting arms are connected to the main connecting bracket via side plates, and the side plates are provided with first connecting holes for connecting to the compressor. The side plates on both sides can not only improve the connection strength between the first and second connecting arms and the main connecting bracket, but also serve as the main connection points to ensure a firm connection between the main connecting bracket and the compressor.

[0008] Preferably, the top of the secondary connecting bracket is connected to the main connecting bracket through multiple second connecting holes, and the side plate on the second connecting arm is connected to the side of the secondary connecting bracket through a first auxiliary connecting plate. The interaction between the second connecting holes and the first auxiliary connecting plate can ensure the connection strength between the secondary connecting bracket and the main connecting bracket.

[0009] Preferably, the edge of the hollow portion on the main connecting bracket is connected to the compressor via at least one second auxiliary connecting plate, which can connect the compressor to the main connecting bracket from the top.

[0010] Preferably, the shock-absorbing connection assembly includes a rubber pad and an inner ring flange passing through the middle inner hole of the rubber pad. The rubber pad is embedded in the corresponding mounting holes on the first connecting arm, the second connecting arm, the third connecting arm, and the fourth connecting arm. The inner ring flange can be connected to the vehicle body, and the upper and lower end faces of the rubber pad can contact the vehicle body to achieve shock absorption.

[0011] Preferably, the rubber pad has multiple deformation grooves on both the upper and lower end faces, allowing the rubber pad to deform.

[0012] Preferably, a protective plate is provided on the lower side of the first connecting arm. The lower end of the protective plate is connected to the compressor, which can protect the pipeline on the side of the compressor and improve the connection strength from the side.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] With a simple structure, the compressor and fan can be integrated together for vibration damping by setting the main and auxiliary connecting brackets. The suspended installation of the four vibration damping connecting components can greatly reduce the vibration of the compressor and fan during operation. The drainer is installed by setting the transverse support plate, so that the airflow output by the compressor during operation can be drained in time without the need for a separate mounting bracket to install the drainer. Moreover, the main and auxiliary connecting brackets are set along the outer contour of the compressor and fan, which can minimize the installation space and reduce the motion envelope of the compressor when the vehicle body is subjected to vibration, resulting in good vibration damping effect and optimizing the NVH effect of the whole vehicle.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figure 1-5 As shown, in order to solve the problems of complex installation structure, poor shock absorption effect, and inability to effectively integrate the compressor body and cooling fan of existing oxygen concentrator compressor air source systems, the following technical solution is provided: a vehicle-mounted oxygen concentrator compressor body connection bracket, including a main connection bracket 1 for connecting to the compressor 12 and a secondary connection bracket 2 for connecting to the fan 9, wherein the main connection bracket 1 is arranged horizontally and the secondary connection bracket 2 is arranged vertically. One side of the main connection bracket 1 is connected to the secondary connection bracket 2. The side of the main connection bracket 1 is provided with an outwardly extending first connection arm 4 and a second connection arm 3. The sides of the main connection bracket 1 and the secondary connection bracket 2 opposite to the first connection arm 4 are respectively provided with an outwardly extending third connection arm 14 and a fourth connection arm 15. The first connection arm 4, the second connection arm 3, the third connection arm 14 and the fourth connection arm 15 are all equipped with shock-absorbing connection components 6 for vehicle body connection. The lower side of the secondary connection bracket 2 includes a transverse support plate 8 for installing a drainer 10. The technical solution in this embodiment precisely adapts the installation posture of the compressor 12 and the fan 9 through the vertical connection structure of the horizontally set main connecting bracket 1 and the vertically set secondary connecting bracket 2, realizing the integration of the two. Compared with the existing separate installation structure, it reduces multiple independent brackets, greatly reduces the number of parts, and saves installation space.

[0024] Moreover, the four connecting arms are symmetrically distributed in a rectangle, with an adjacent arm spacing of 80-120mm, so that the connection point between the bracket and the vehicle body forms a stable four-point support and the force is evenly distributed; the suspended installation design of the shock-absorbing connecting component 6 can greatly reduce the vibration transmission rate of the compressor 12 and the fan 9, and significantly optimize the NVH performance of the whole vehicle.

[0025] The horizontal support plate 8 on the lower side of the auxiliary connecting bracket 2 is integrally formed with the auxiliary connecting bracket 2, eliminating the need for additional design of the drain 10 installation parts. At the same time, it ensures that the drain 10 is located at the lowest end of the outlet pipe of the compressor 12, so that the water vapor in the airflow can be effectively settled and concentrated.

[0026] In this embodiment, both the main connecting bracket 1 and the auxiliary connecting bracket 2 are frame-type structures. Each of the main connecting bracket 1 and the auxiliary connecting bracket 2 has a hollow portion 7 that matches the shape of the compressor 12 and the fan 9. Compared to a flat plate structure, the frame-type structure of the main connecting bracket 1 and the auxiliary connecting bracket 2 significantly improves rigidity and effectively avoids resonance caused by deformation of the bracket itself. The matching degree between the hollow portion 7 and the shape of the compressor 12 and the fan 9 is controlled within a 5-10mm gap, which avoids installation interference and increases airflow through the hollow area, assisting in heat dissipation of the compressor and fan. Simultaneously, the hollow design reduces the overall weight of the bracket, such as from 1.5kg to 1.0kg, reducing the vehicle body load.

[0027] In this embodiment, the roots of the first connecting arm 4 and the second connecting arm 3 are connected to the main connecting bracket 1 via side plates 5. The side plates 5 are provided with first connecting holes 16 for connecting to the compressor 12. The side plates 5 on both sides can not only improve the connection strength between the first connecting arm 4 and the second connecting arm 3 and the main connecting bracket 1, but also serve as the main connection point to ensure a firm connection between the main connecting bracket 1 and the compressor 12. Specifically, the first connecting holes 16 on the side plates 5 are M6 threaded holes with a hole spacing of 30-40mm, which precisely match the mounting holes on the compressor 12 housing. The compressor is connected by high-strength bolts, making the connection between the compressor and the main connecting bracket 1 more secure and reducing secondary vibration caused by loosening.

[0028] In this embodiment, the top of the secondary connecting bracket 2 is connected to the main connecting bracket 1 through multiple second connecting holes 21. At the same time, the side plate 5 on the second connecting arm 3 is connected to the side of the secondary connecting bracket 2 through a first auxiliary connecting plate 22. There can be 2-3 second connecting holes 21 on the top of the secondary connecting bracket 2. It is connected to the main connecting bracket 1 by bolts and forms a three-dimensional fixed structure with the first auxiliary connecting plate 22. The first auxiliary connecting plate 22 and the side plate 5 can be connected by screws or welding to control the relative displacement of the main and secondary brackets within 0.05mm, ensuring the relative position stability of the fan 9 and the compressor 12 and avoiding pipeline connection fatigue.

[0029] In this embodiment, the edge of the hollow portion 7 on the main connecting bracket 1 is connected to the compressor 12 through at least one second auxiliary connecting plate 11. The second auxiliary connecting plate 11 can connect the compressor 12 and the main connecting bracket 1 from the top. Specifically, the second auxiliary connecting plate 11 can be L-shaped, has high strength, and is integrally formed with the main connecting bracket 1. It is connected to the top of the compressor by M4 bolts, and the connection with the side plate 5 forms a three-dimensional fixing method at the top and both sides, which further suppresses the transmission of high-frequency vibration.

[0030] As a specific embodiment of the shock-absorbing connection component 6, such as Figure 5 As shown, the shock-absorbing connection assembly 6 includes a rubber pad 63 and an inner flange 61 passing through the inner hole of the rubber pad 63. The rubber pad 63 is embedded in the corresponding mounting holes on the first connecting arm 4, the second connecting arm 3, the third connecting arm 14, and the fourth connecting arm 15. Specifically, in the shock-absorbing connection assembly, the rubber pad 63 is made of nitrile rubber with a hardness of 60±5 Shore A, and is embedded in the mounting holes of the arm with an interference fit to ensure that there is no relative sliding between the rubber pad 63 and the arm. The inner flange 61 passes through the inner hole of the rubber pad 63 and is bolted to the body, absorbing vibration energy through the elastic deformation of the rubber. In addition, multiple deformation grooves 62 are provided on the upper and lower end faces of the rubber pad 63. The deformation grooves 62 provide additional deformation space for the rubber, increasing the deformation of the rubber pad under the same load, further improving the absorption effect of low-frequency vibration. At the same time, the deformation grooves 62 can store a small amount of lubricating grease, reducing friction and wear between the rubber and the body / arm, and extending the service life.

[0031] In addition, a guard plate 13 is provided on the lower side of the first connecting arm 4. The lower end of the guard plate 13 is connected to the compressor 12. The guard plate 13 forms physical protection for the air inlet and outlet pipes of the compressor 12, reducing the probability of the pipes being damaged by vehicle bumps and collisions. At the same time, the rigid connection of the guard plate 13 restricts the lateral displacement of the compressor side and forms a multi-directional constraint with the main connecting bracket 1, improving the overall stability.

[0032] As part of the installation steps for the connecting bracket in this embodiment:

[0033] 1. Place the compressor 12 inside the hollow part 7 of the main connecting bracket 1, and fix both sides of the compressor 12 through the first connecting hole 16 on the side plate 5; at the same time, fix the top of the compressor 12 through the two second auxiliary connecting plates 11 on the edge of the hollow part 7 of the main connecting bracket 1, to ensure that the compressor 12 and the main bracket 1 are not loose relative to each other.

[0034] 2. Embed the fan 9 into the hollow part 7 of the secondary connecting bracket 2, and connect the fan 9 to the secondary connecting bracket 2 with bolts through the mounting holes of the fan 9, ensuring that the axis of the fan 9 coincides with the vertical center line of the secondary connecting bracket 2;

[0035] 3. The top of the secondary connecting bracket 2 is connected to one side of the main connecting bracket 1 through two second connecting holes 21. At the same time, the side plate 5 of the second connecting arm 3 is connected to the side of the secondary connecting bracket 2 through the first auxiliary connecting plate 22 to form a triangular support.

[0036] 4. Insert rubber pads 63 into the mounting holes of the first connecting arm 4, the second connecting arm 3, the third connecting arm 14, and the fourth connecting arm 15 with an interference fit, and pass the inner ring flange 61 through the inner hole of the rubber pad 63 to complete the assembly of the shock-absorbing connecting assembly 6.

[0037] 5. Fix the drainer 10 to the horizontal support plate 8 on the lower side of the auxiliary connecting bracket 2 with M5 bolts to ensure that the inlet of the drainer 10 is connected to the air pipe of the compressor 12.

[0038] 6. The inner flange 61 of the shock-absorbing connection component 6 is connected to the preset mounting point on the vehicle body to complete the fixation of the entire bracket to the vehicle body. At this time, the entire bracket is in a suspended state.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
