Technical Field

The invention relates to the field of vehicle-mounted compressors, in particular to a compressor movement limiting structure.

Background

Conventional compressors are typically used in static environments, such as household refrigerators and freezers, where the work site is smooth. Along with the refrigeration field is constantly enlarged, the application of compressor is more and more extensive, the operational environment of compressor has also changed, for example on using on-vehicle refrigerator, on the portable refrigeration plant of medical field, the operational environment of compressor becomes jolting at this moment, vibration is also relatively great, current compressor anticollision technique, mainly arrange the anticollision point on the core, the material of anticollision point is the metal usually, when the operational environment of compressor is not steady, the spring probably takes place great deformation, the anticollision point and the casing of core bump, produce sharp-pointed metal impact sound easily. Therefore, a compressor movement limiting structure is needed to be designed, so that transition inclination of the compressor is prevented, and sharp sound generated by collision between the movement and the shell can be avoided.

Disclosure of Invention

The invention provides a compressor movement limiting structure, which aims to overcome the defects that a spring is likely to deform greatly, an anti-collision point of a movement collides with a shell and sharp metal impact sound is easily generated when the working environment of a compressor is not stable in the prior art, and can prevent the compressor from inclining excessively and avoid the movement from colliding with the shell to generate sharp sound.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a compressor core limit structure, includes casing, core, spacing cover, support and anticollision component, spacing cover is fixed at the inside top region of casing, and the support is fixed on the core, and the anticollision component is fixed on the support, and the one end of anticollision component sets up in the spacing cover, is equipped with the clearance between anticollision component and the spacing cover.

Among the above-mentioned technical scheme, spacing cover passes through welded fastening at the inside top region of casing, and anticollision component is non-metallic material. The anti-collision element moves in the area limited inside the limiting cover, the movement range of the movement in the horizontal direction and the vertical direction is limited, when the compressor runs in an inclined state, the anti-collision element is in contact with the limiting cover, and the anti-collision element is made of a non-metal material, so that the impact sound is very small.

Preferably, the impact element is fixed to the bracket by injection molding. The fixing mode can increase the strength of the connecting structure and ensure the stability of the structure.

Preferably, the support is provided with a connecting hole used for being connected with the anti-collision element in an injection molding mode, the bottom of the anti-collision element is provided with a first supporting ring and a second supporting ring, the outer diameters of the first supporting ring and the second supporting ring are larger than the diameter of the connecting hole, and the first supporting ring and the second supporting ring are arranged at two ends of the connecting hole respectively. The structure can make the connection of anticollision component and support more stable, is difficult to not hard up.

Preferably, the impact protection element is fixed to the bracket by means of a catch. The structure facilitates quick installation and replacement of the impact element.

Preferably, the clamping jaw comprises a claw-shaped structure and a base, the anti-collision element is clamped and fixed with the clamping jaw through the claw-shaped structure, and the base is welded and fixed with the support. The claw and the anti-collision element are fixed together through deformation of the claw-shaped structure.

Preferably, the distance between the top of the collision-prevention element and the top of the inner wall of the limit cover is less than half of the height of the inner wall of the limit cover. The structure can guarantee that the anti-collision element has enough size to be located in the inner wall of the limiting cover, and the reliability of the limiting structure is guaranteed.

Preferably, the maximum cross-sectional dimension of the head of the impact-prevention element is d1, and the minimum cross-sectional dimension of the inner wall of the limit shield is d2, d1 < d 2. The structure can ensure the clearance between the anti-collision element and the inner wall of the limit cover.

Preferably, the surface of the anti-collision element is provided with an elastic rubber sleeve. The elastic rubber sleeve can play a role in buffering and reducing noise.

Preferably, the surface of the anti-collision element is provided with a plurality of elastic bulges. The elastic bulge 5.2 is easier to deform relative to the anti-collision element, and the vibration and noise reduction effect of the anti-collision element can be improved.

The invention has the beneficial effects that: (1) meanwhile, the movement range of the movement in the horizontal direction and the vertical direction is limited, when the compressor runs in an inclined state, the anti-collision element is in contact with the limiting cover, and the anti-collision element is made of a non-metal material, so that the impact sound is very small.
