Abstract
Description
Technical Field
[0001] This utility model belongs to the field of compressor technology, and in particular relates to a shock-absorbing compressor and a vehicle refrigerator. Background Technology
[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas; it is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by an electric motor, and then discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe, providing power for the refrigeration cycle. Compressors are used in mobile refrigeration applications such as commercial vehicles, RVs, trucks, luxury cars, and refrigerated trucks. Furthermore, with the rapid development of modern electric vehicles, in-vehicle refrigerators have become an indispensable automotive component, thus increasing the demand for compressors for in-vehicle refrigerators.
[0003] In existing technology, the structure of a vehicle refrigerator compressor mainly includes a metal casing, a core, and a rubber ring. The core is installed inside the casing, and the rubber ring is installed on the upper part of the core to mitigate compressor vibration. However, when the compressor starts while the vehicle is in motion, because the rubber ring is only installed on the upper part of the core for protection, the outer and bottom surfaces of the core still collide with the casing. This collision not only causes significant vibration and noise, affecting the experience of the driver and passengers, but also leads to core displacement or detachment, affecting the normal operation of the compressor and thus reducing its lifespan. Utility Model Content
[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a shock-absorbing compressor. By using a first elastic element and a first limiting element in combination, the upper and lower end faces of the compressor core are protected. By using a second elastic element and a second limiting element in combination, all-round protection of the compressor core is achieved, reducing the impact between the compressor cores. This not only effectively solves the problem of large-amplitude vibration and noise caused by the compressor core colliding with the housing, improving the experience of the driver and passengers, but also avoids the problems of compressor core displacement and detachment, increasing the service life of the compressor.
[0005] This utility model provides a shock-absorbing compressor, including an upper housing, a lower housing, and a core; the core is disposed between the upper housing and the lower housing, a first elastic element is disposed at the upper end of the core, a first limiting element is disposed at the lower end of the upper housing relative to the first elastic element, the first elastic element is located inside the first limiting element, a second elastic element is disposed at the outer periphery of the core, and a second limiting element is disposed at the lower end of the upper housing away from the first limiting element, the second limiting element being disposed opposite to the upper end of the second elastic element.
[0006] Optionally, the first elastic element includes an elastic protrusion with a "┐"-shaped transverse cross-section, the elastic protrusion covering the top and sides of the movement; the top and sides of the movement are in elastic contact with the inner wall of the upper housing through the elastic protrusion.
[0007] Optionally, the second elastic element includes at least two elastic blocks, which are symmetrically distributed on the side wall of the movement; the side of the movement away from the first elastic element is in elastic contact with the inner wall of the lower housing through the elastic blocks.
[0008] Optionally, the first limiting member includes two limiting protrusions, which are respectively disposed at both ends of the first elastic member, and the limiting protrusions can be used to limit the lateral movement position of the first elastic member.
[0009] Optionally, the second limiting member includes at least two limiting rods, which are disposed on the top of the second elastic member and are used to limit the longitudinal movement position of the second elastic member.
[0010] Optionally, a certain gap is provided between the limiting protrusion and the elastic protrusion, and a certain gap is provided between the limiting rod and the elastic block.
[0011] Optionally, a spring mounting position is provided inside the lower housing, and a third elastic element corresponding to the spring mounting position is provided at the lower end of the movement. The bottom surface of the movement is in elastic contact with the spring mounting position of the lower housing through the third elastic element.
[0012] Optionally, the third elastic element includes at least four elastic supports; the four elastic supports are evenly distributed on the lower surface of the movement.
[0013] Optionally, the first elastic element, the second elastic element, and the third elastic element are elastic elements made of rubber and / or silicone materials.
[0014] This utility model also provides a vehicle-mounted refrigerator, including the aforementioned compressor.
[0015] This utility model also provides a vehicle refrigerator, including the compressor described above.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. By cooperating with the first limiting member on the upper housing and the first elastic member on the mechanism, as well as the second limiting member and the second elastic member on the mechanism, the collision between the mechanism and the housing is mitigated. Specifically, when the compressor starts during dynamic operation of the vehicle, the first elastic member installed on the upper end of the mechanism creates elastic contact between the top and side surfaces of the mechanism and the inner wall of the upper housing, preventing direct collision between the top and side surfaces of the mechanism and the housing. Furthermore, the first limiting member limits the longitudinal movement of the mechanism within the housing. Simultaneously, the second elastic member installed on the outer circumference of the mechanism... The outer peripheral surface of the mechanism forms an elastic contact with the inner wall of the upper housing, avoiding direct collision between the outer peripheral surface of the mechanism and the housing. In addition, the second limiting component limits the lateral movement of the mechanism. Therefore, the first and second elastic components on the mechanism can achieve all-round protection of the mechanism, reduce the collision between the mechanism and the housing, effectively solve the problem of large-amplitude vibration and noise after the mechanism collides with the housing, and improve the experience of the driver and passengers. At the same time, the limiting components prevent the mechanism from shifting or falling out, and increase the service life of the compressor.
[0018] 2. The movement is mounted in the spring mounting position of the lower housing via a third elastic element (which includes at least four elastic supports) at the lower end of the movement. Since the movement is connected to the spring mounting position via the elastic supports in this application, the coefficient of friction between the contact surface between the movement and the spring mounting position is effectively increased, further improving the stability of the movement and avoiding the risk of the movement coming out of the spring mounting position.
[0019] 3. Because there is a certain gap between the limiting protrusion and the elastic protrusion, and a certain gap between the limiting rod and the elastic block, there is a certain buffer space between the movement and the upper and lower housings, which provides a certain buffer space between the movement and the housing, and further improves the shock absorption effect of the movement.
[0020] 4. The first, second, and third elastic elements are made of rubber and / or silicone materials. Since rubber and silicone have high elasticity, weather resistance, insulation, and sealing properties, they can effectively provide cushioning and protection for the engine core, reduce vibration and noise generated during engine use, and improve the stability of the compressor during use.
[0021] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation
[0029] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0030] This utility model provides a shock-absorbing compressor, including an upper housing 01, a lower housing 02, and a core 03; the core 03 is disposed between the upper housing 01 and the lower housing 02, a first elastic element 031 is disposed at the upper end of the core 03, a first limiting element 011 is disposed at the lower end of the upper housing 01 relative to the first elastic element 031, the first elastic element 031 is located inside the first limiting element 011, a second elastic element 032 is disposed on the outer periphery of the core 03, and a second limiting element 012 is disposed at the lower end of the upper housing 01 away from the first limiting element 011, the second limiting element 012 is disposed opposite to the upper end of the second elastic element 032.
[0031] By cooperating with the first limiting member 011 on the upper housing 01, the first elastic member 031 on the mechanism 03, and the second limiting member 012 and the second elastic member 032 on the mechanism 03, the collision between the mechanism 03 and the housing is mitigated. Specifically, when the compressor starts during dynamic operation of the vehicle, the first elastic member 031 installed on the upper end of the mechanism 03 makes elastic contact between the top and side surfaces of the mechanism 03 and the inner wall of the upper housing 01, avoiding direct collision between the top and side surfaces of the mechanism 03 and the housing. Furthermore, in conjunction with the limiting effect of the first limiting member 011, the longitudinal movement position of the mechanism 03 within the housing is limited. Simultaneously, the second elastic member 032 installed on the outer circumferential surface of the mechanism 03 makes contact between the outer circumferential surface of the mechanism 03 and the inner wall of the upper housing 01. The walls form an elastic contact, preventing direct collision between the outer peripheral surface of the mechanism 03 and the housing. Furthermore, the second limiting member 012 limits the lateral movement of the mechanism 03. Therefore, the first elastic member 031 and the second elastic member 032 on the mechanism 03 provide all-around protection, reducing the impact between the mechanism 03 and the housing. This effectively solves the problem of significant vibration and noise after the mechanism 03 collides with the housing, improving the driver's experience. Simultaneously, the first limiting member 011 and the second limiting member 012 limit the lateral (i.e., longitudinal) movement, ensuring the initial position of the mechanism 03 within the housing remains unchanged, preventing displacement or detachment of the mechanism 03, and increasing the compressor's lifespan.
[0032] In a preferred embodiment, the first elastic element 031 includes an elastic protrusion 0311, the transverse cross section of which is arranged in a "┐" shape, and the elastic protrusion 0311 covers the top and side of the movement 03; the top and side of the movement 03 are in elastic contact with the inner wall of the upper housing 01 through the elastic protrusion 0311.
[0033] Specifically, the upper end face of the "┐"-shaped elastic protrusion 0311 is located on the upper surface of the top of the movement 03, forming an upper buffer layer to separate the top of the movement 03 from the inner side of the upper housing 01, thus preventing direct collision between the top of the movement 03 and the upper housing 01. The side end face of the "┐"-shaped elastic protrusion 0311 is located on the left side of the movement 03, forming a left buffer layer to separate the left side of the movement 03 from the inner side of the upper housing 01, thus preventing direct collision between the left side of the movement 03 and the upper housing 01.
[0034] In a preferred embodiment, the second elastic element 032 includes at least two elastic blocks 0321, which are symmetrically distributed on the side wall of the movement 03; the side of the movement 03 away from the first elastic element 031 is in elastic contact with the inner wall of the upper housing 01 through the elastic blocks 0321.
[0035] Specifically, the two elastic blocks 0321 are symmetrically distributed on the left side of the movement 03 to form a left-end buffer layer, which is used to separate the left side of the movement 03 from the inner side of the lower housing 02, so as to avoid direct collision between the left side of the movement 03 and the lower housing 02.
[0036] In a preferred embodiment, the first limiting member 011 includes two limiting protrusions 0111, which are respectively disposed at both ends of the first elastic member 031, and the limiting protrusions 0111 can be used to limit the lateral and longitudinal movement positions of the first elastic member 031.
[0037] In a preferred embodiment, the second limiting member 012 includes at least two limiting rods 0121, the limiting rods 0121 being disposed on the top of the second elastic member 032, and the limiting rods 0121 being used to limit the longitudinal movement position of the second elastic member 032.
[0038] Specifically, the two limiting rods 0121 have an "L"-shaped transverse cross-section, and the limiting rods 0121 are welded and fixed to the upper housing 01.
[0039] In a preferred embodiment, a certain gap is provided between the limiting protrusion 0111 and the elastic protrusion 0311, and a gap is provided between the limiting rod 0121 and the elastic block 0321.
[0040] Because there is a certain gap between the limiting protrusion 0111 and the elastic protrusion 0311, and a certain gap between the limiting rod 0121 and the elastic block 0321, there is a certain buffer space between the movement 03 and the upper housing 01 and the lower housing 02, which provides a certain buffer space between the movement 03 and the housing, and further improves the shock absorption effect of the movement 03.
[0041] In a preferred embodiment, a spring mounting position 021 is provided inside the lower housing 02, and a third elastic element 033 corresponding to the spring mounting position 021 is provided at the lower end of the movement 03. The bottom surface of the movement 03 is in elastic contact with the spring mounting position 021 of the lower housing 02 through the third elastic element 033. Furthermore, the third elastic element 033 includes at least four elastic support pillars 0331; the four elastic support pillars 0331 are evenly distributed on the lower surface of the movement 03.
[0042] The movement 03 is mounted in the spring mounting position 021 of the lower housing 02 via a third elastic element 033 (which includes at least four elastic supports 0331) at the lower end of the movement 03. In the prior art, the insulating parts of the movement are all made of plastic (plastic has a lower coefficient of friction than rubber or silicone). Therefore, when the movement is mounted in the spring mounting position, the contact surface between the movement and the spring mounting surface is smooth and easy to detach. In this application, the movement 03 is connected to the spring mounting position 021 via the elastic supports 0331 (made of rubber and / or silicone), effectively increasing the coefficient of friction between the movement 03 and the spring mounting position 021, further improving the stability of the movement 03, and avoiding the risk of the movement 03 detaching from the spring mounting position 021.
[0043] In a preferred embodiment, the first elastic element 031, the second elastic element 032, and the third elastic element 033 are elastic elements made of rubber and / or silicone materials.
[0044] The first elastic element 031, the second elastic element 032, and the third elastic element 033 are elastic elements made of rubber and / or silicone materials. Since rubber and silicone have high elasticity, weather resistance, insulation, and sealing properties, they can effectively provide buffering and protection for the core 03, reduce vibration and noise generated during engine use, and improve the stability of the compressor during use.
[0045] This utility model also provides a vehicle refrigerator, including the compressor described above.
[0046] 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.
