Description

Technical Field

[0001] The utility model belongs to the technical field of compressor shock absorption, and in particular relates to a compressor shock absorption structure of a vehicle-mounted oxygen concentrator. Background Art

[0002] The compressor of a vehicle-mounted oxygen concentrator is affected by complex vibrations during vehicle driving, including engine vibration, road bumps, and multi-directional impacts caused by dynamic movement of the vehicle body. The traditional compressor shock-absorbing structure of a vehicle-mounted oxygen concentrator mostly adopts a longitudinal spring-type single-stage shock-absorbing structure or a rigid fixing method, which has the following problems: (1) Limited shock-absorbing effect: The single-stage shock-absorbing structure is difficult to effectively absorb multi-band and multi-directional vibration energy, resulting in vibration transmission to the compressor body, affecting its operating stability and life; (2) Poor spatial adaptability: The vehicle-mounted environment has strict requirements on the volume and weight of the equipment. The traditional compressor shock-absorbing structure has a loose layout and occupies a large space, which is difficult to meet the compact installation requirements; (3) High resonance risk: The low-frequency vibration generated by the compressor and the vehicle during driving is prone to cause resonance, aggravating equipment fatigue damage; (4) Complex installation and maintenance: Some single-stage shock-absorbing structures require multi-step assembly or special tools, which increases maintenance costs. Therefore, there is an urgent need for a compressor shock-absorbing structure of a vehicle-mounted oxygen concentrator that can adapt to the vehicle-mounted environment, has multi-stage shock-absorbing capabilities, and has a compact structure. Utility Model Content

[0003] The utility model aims at the above-mentioned problems, makes up for the deficiencies of the prior art, and provides a compressor shock-absorbing structure for a vehicle-mounted oxygen concentrator; efficient vibration isolation is achieved through a double-stage shock-absorbing structure design, while optimizing the structural layout to adapt to the vehicle-mounted space.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model provides a compressor damping structure of a vehicle-mounted oxygen concentrator, comprising a primary damping structure and a secondary damping structure, wherein the primary damping structure is connected to the upper end of the secondary damping structure, the compressor passes through the primary damping structure and falls into the secondary damping structure, and a mounting orifice plate located in the middle of the compressor is fixedly connected to the primary damping structure.

[0006] The primary shock-absorbing structure includes a shock-absorbing plate and a first shock absorber, and the first shock absorber is evenly distributed on the side of the shock-absorbing plate; the secondary shock-absorbing structure includes a shock-absorbing frame and a second shock absorber, the upper end of the shock-absorbing frame is open, the shock-absorbing plate is arranged in the opening, the shock-absorbing plate is connected to the upper end of the shock-absorbing frame through the first shock absorber, the second shock absorber is evenly distributed on the bottom of the shock-absorbing frame, and the shock-absorbing frame is installed in the vehicle-mounted oxygen concentrator through the second shock absorber.

[0007] Furthermore, a mounting hole for the compressor to pass through is provided in the central area of ​​the shock absorbing plate.

[0008] Furthermore, the upper surface of the shock-absorbing plate around the installation hole is provided with fixing holes for connecting with the mounting hole plate in the middle of the compressor, and the mounting hole plate and the fixing holes are connected by bolts.

[0009] Furthermore, a snap-in groove for corresponding connection with the first shock absorber is opened on the upper side of the shock absorbing frame, and a locking member composed of screws, flat washers and spring washers is threadedly connected through the snap-in groove and the first shock absorber to fix the shock absorbing plate and the shock absorbing frame together.

[0010] Furthermore, a weight-reducing hole is provided on the side surface of the shock-absorbing frame.

[0011] Furthermore, two opposite sides of the bottom of the shock absorbing frame are respectively connected with outward wing plates, and the second shock absorbers are respectively connected to the bottoms of both ends of the outward wing plates.

[0012] Furthermore, the first shock absorber and the second shock absorber are both DD type rubber shock absorbers.

[0013] Beneficial effects of the utility model:

[0014] Compared with the prior art, the utility model has the following significant advantages:

[0015] (1) Synergistic effect of two-stage shock absorption: the first-stage shock absorption structure absorbs the lateral vibration of the compressor through the first shock absorber arranged laterally, and the second-stage shock absorption structure attenuates the vertical impact through the second shock absorber at the bottom, forming a multi-dimensional shock absorption barrier to reduce the vibration transmission rate;

[0016] (2) Compact and lightweight structure: The weight-reducing hole design of the shock-absorbing frame reduces the overall weight while ensuring rigidity. The outward-facing wing panels expand the bottom support area, enhancing stability without increasing space occupancy.

[0017] (3) Excellent anti-resonance performance: By adopting DD-type rubber shock absorbers with high damping characteristics, low-frequency resonance can be effectively suppressed to avoid coupling between the compressor and vehicle vibration frequency;

[0018] (4) Convenient and reliable installation: The mounting orifice plate and the fixed hole are connected by bolts to achieve quick positioning of the compressor. The card slot and the locking piece cooperate to ensure the stable assembly of the primary shock-absorbing structure and the secondary shock-absorbing structure, reducing the complexity of maintenance;

[0019] (5) Enhanced environmental adaptability: The dual-stage shock-absorbing layout adapts to complex vehicle operating conditions, especially suitable for bumpy roads or long-term operation scenarios, significantly extending the service life of the compressor. BRIEF DESCRIPTION OF THE DRAWINGS
