Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a vehicle-mounted refrigerator compressor. Background Technology

[0002] Car refrigerators, which can be carried in cars or used as portable refrigerators, use a compressor to drive refrigeration. However, existing car refrigerator compressors generally have some defects. For example, the noise generated during the compressor's intake process, the high-frequency noise generated when the compressor discharges high-pressure gas, and the vibration noise generated inside the compressor itself all affect the user experience. However, existing devices mostly use external sound insulation cotton to isolate noise, which is difficult to solve the noise problem from the inside. The compressor requires internal wiring, namely the compressor motor wiring. The resulting connectors are mostly either directly suspended or pressed between the compressor and the outer casing. However, the suspension will cause the connector to be subjected to force with the vibration of the compressor, which will easily lead to the wire harness coming off over time. The pressed installation method is prone to collision damage to the connector due to changes in distance caused by the vibration between the compressor and the outer casing. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0027] See Figures 1-31As shown, it includes an outer shell 1. Multiple protrusions are provided at the bottom of the inner shell 1, and sleeves 33 are installed through these protrusions. Sleeves 33 are replaceable. A compression housing 7 for gas compression is located inside the outer shell 1. A canister cover 16 is installed on the front side of the compression housing 7. A valve plate 18 is located between the compression housing 7 and the canister cover 16. A piston hole 22 for piston action to compress gas is opened inside the compression housing 7.

High-pressure air holes 19 are opened on both sides of the valve plate 18, and both high-pressure air holes 19 are connected to the outlet chamber 27. Two sets of flow channels are opened inside the compression housing 7, and the two high-pressure air holes 19 are respectively connected to the two sets of flow channels. Both sets of flow channels are connected to the exhaust holes 28 for gas discharge. An insulating seat 2 is located inside the compressor. 2. A card holder 44 is snapped into the bottom. The card holder 44 has a groove for the connecting wire harness 45 of the compressor to pass through. The insulating seat 2 has a second card slot 15 for positioning the wire end on both sides. Multiple stator damping blocks 5 are detachably installed on the insulating seat 2. The insulating seat 2 is located in the motor inside the compressor housing 1. The stator damping blocks 5 are all located on the outside of the insulating seat 2. A can cover damping block 8 is detachably installed on the can cover 16 behind the compressor housing 7. A muffler is connected to the compressor housing 7, including a muffler body 32. The shape of the muffler matches the installation position of the compressor. It forms a cavity inside and is divided into a first chamber 37 and a second chamber 38 by a partition plate 36. The two chambers are connected. An air inlet 35 is provided on the bottom side of the muffler body 32 and is connected to the first chamber 37. An air outlet 40 is provided on the top of the muffler body 32 and is connected to the second chamber 38. The insulating base 2 has a position for installing the stator damping block 5. There are protruding side locking protrusions 4 on both sides, and an alignment insertion hole 6 is opened in the middle of the upper side. There are locking holes 3 on both sides of the alignment insertion hole 6. The stator damping block 5 is a flexible stator damping block 501, made of resin or polyurethane foam and other materials. It has a certain flexible damping function, as well as a certain rigidity, and can maintain its own shape. The interior has a slot 5011 facing downward. The shape of the slot 5011 matches the shape of the mounting part on the insulating base 2 and the outer shape of the side protrusion 4. The inner middle of the flexible stator damping block 501 is connected to the alignment plug 5014. The alignment plug 5014 has a locking post 5012 on both sides. The bottom end of the locking post 5012 has a locking buckle 5013 facing one side. After the flexible stator damping block 501 is installed on the insulating base 2, the alignment plug 5014 is inserted into the alignment hole 6, the locking post 5012 is inserted into the locking hole 3, and the locking buckle 5013 is locked below the locking hole 3. The shock absorber is installed using a snap-fit ​​method, which allows it to maintain a stable connection and provide shock absorption for the stator.

[0028] See Figures 1-14 As shown, one set of flow channels is a buffer chamber 23 opened on the compression housing 7, located to the side of the exhaust port 28. A venting groove 29 is opened on the surface of the compression housing 7 between the buffer chamber 23 and the exhaust port 28. The other set of flow channels includes a second buffer chamber 24 and a third buffer chamber 25 opened on the compression housing 7. A high-pressure air hole 19 away from the exhaust port 28 is connected to the third buffer chamber 25. The second buffer chamber 24 is opened between the third buffer chamber 25 and the exhaust port 28. Venting grooves 29 for gas flow are opened between the third buffer chamber 25 and the second buffer chamber 24, and between the second buffer chamber 24 and the exhaust port 28. The root of the exhaust port 28 is opened... The valve plate 18 and the can lid 16 are threaded and have holes opposite to the vent 28. The can lid 16 is installed on the outside of the valve plate 18 by screws. One screw is connected to the thread through the aforementioned hole. A vent ring 30 is pressed inside the screw. A high-pressure copper pipe 17 for conveying high-pressure gas is connected to the vent ring 30. A vent hole 31 is opened in the vent ring 30, which is connected to the high-pressure copper pipe 17. The high-pressure copper pipe 17 rotates around the top of the motor to form multiple arcs, so that the copper pipe forms an arc-shaped buffer structure. When subjected to external force or vibration, it can distribute the force evenly to various places, thereby automatically offsetting the kinetic energy and preventing the kinetic energy from concentrating and causing damage. The valve plate 18 also has an air inlet 20 connected to the piston hole 22 for connecting to the muffler outlet 40 for air intake. An air inlet valve plate is provided inside the air inlet 20. After the gas is compressed in the piston orifice 22, the high-pressure gas passes through the outlet valve plate 21 and enters the outlet chamber 27 through the outlet passage 26 for the first buffering. Then, it passes through two high-pressure gas holes 19 and is sent into the first buffer chamber 23 and the third buffer chamber 25 respectively. The gas in the first buffer chamber 23 is directly discharged into the exhaust port 28, while the gas in the third buffer chamber 25 passes through the second buffer chamber 24 and then enters the exhaust port 28. The separation of the second buffer chamber 24 and the third buffer chamber 25 is necessary to ensure the strength of the compression shell 7, thus preventing the structural strength from decreasing due to an excessively long cavity. The outlet chamber 27 and the two sets of buffer channels allow the high-pressure output gas to undergo two buffering processes, reducing pulse and airflow noise. By installing the vent ring 30, the copper pipe is installed and pressed tightly while the outer cover is being installed, ensuring gas flow.

[0029] See Figures 1-25As shown, the partition plate 36 is T-shaped. The bottom of the vertical part of the T is connected to the side wall of the cavity to form a partition, while the horizontal part forms a flow channel with the other side of the cavity. The top of the muffler body 32 is provided with a vertical air guide chamber 39, and the air outlet 40 is connected to the top of the air guide chamber 39. The bottom of the air guide chamber 39 is connected to the second chamber 38 at the intersection of the horizontal and vertical parts of the T-shaped partition plate 36. At the bottom of the muffler body 32, there are two oil drain holes 41, which are located at the bottom of the first chamber 37 and the second chamber 38, respectively. The bottom of the muffler body 32 is provided with a rim 42, which is located outside the two oil drain holes 41.

[0030] The design of the partition plate 36 enhances the overall strength of the hollow muffler and increases the internal volume of the two chambers, improving the muffler effect and reducing noise generated by air intake. From the perspective of the figure, after the gas enters from the left air intake 35, it flows through the first chamber 37, then through the upper flow channel, enters the second chamber 38, and then goes down to the leftmost side of the second chamber 38. Finally, it is discharged from the air guide chamber 39 through the air outlet 40, ensuring that the airflow is forced through the two chambers. The oil drain hole 41 is provided to ensure that the oil can flow out through the oil drain hole 41 when the compressor angle is tilted and oil accidentally enters the muffler, and the compressor angle is straightened. The surrounding edge 42 can ensure that the oil can be discharged in time after it flows out, preventing it from being sucked back or flowing to other places along the bottom of the muffler.

[0031] See Figures 1-31 As shown, the card holder 44 has a fan-shaped structure, and its shape matches the shape of the bottom structure of the motor inside the compressor. A protruding limiting ring 47 is provided below the insulating seat 2. The outer side of the card holder 44 is provided with an upward-facing edging, and multiple card protrusions 48 are provided inside the edging. A slot 2 49 is opened at the root of the outer side of the limiting ring 47, and a card block 50 is provided at the bottom of the slot 2 49. Multiple inserts 46 are provided on the inner side of the card holder 44. In the compressor, slots 34 are formed between the coils of the stator, and the inserts 46 are all inserted into the slots 34. The card slots 15 are all "L" shaped, and their heads are provided with hooks 43 facing inward. Two integrated anti-collision corners 14 are provided on the front side of the insulating base 2.

[0032] During installation, after the connecting harness 45 is installed, the harness is placed into the groove of the card holder 44. The card holder 44 is aligned with the insulating base 2 and pressed down. The insert 46 is inserted into the empty slot 34 for auxiliary guidance, while the locking protrusion 48 contacts the locking block 50 and bends outward under the force until it reaches the slot. The card holder 44 springs back, and the locking protrusion 48 is inserted into the slot to complete the locking. At this time, the locking protrusion 48 is locked below the locking block 50 for a limited position. Example

[0033] The difference between this embodiment and embodiment one is that the stator damping block 5 is a flexible stator damping block 502 made of rubber or silicone, which is more flexible and has a better damping effect. It has an internal groove and is connected to bottom sealing blocks 5021 on both sides of the bottom, so that the internal sides form side locking grooves 5022 that match the shape of the side locking protrusion 4. When the flexible stator damping block 502 is installed on the insulating base 2, the side locking protrusion 4 is locked in the side locking groove 5022.

[0034] Because it uses flexible materials, it is installed in a set, which is convenient for installation and prevents structural deformation from causing it to fall off. Example

[0035] Based on Embodiment 1, the can lid shock absorber 8 is a flexible can lid shock absorber 801, made of materials such as resin or polyurethane foam. It has a certain degree of flexible shock absorption function, as well as a certain degree of rigidity, and can maintain its own shape. Its inner shape matches the shape of the can lid 16. The can lid 16 is installed by mounting bolt 11. The front side of the flexible can lid shock absorber 801 has a hole that matches the size of the screw head of the mounting bolt 11. The rear sides of both ends are connected to "L"-shaped clips 8011. The lower end of the clip 8011 is connected to the front side with a clip head 8012. The screw hole 10 in the compression housing 7 is a through hole at the rear end for mounting bolt 12. The compression housing 7 is provided with recessed slots 9 at the screw holes 10. After the flexible can lid shock absorber 801 is installed, the head of the clip 8011 is located in the slot 9, and the clip head 8012 is locked in the screw hole 10.

[0036] The front end of the resilient tank cover shock absorber 801, which adopts a snap-fit ​​method, is fitted onto the screw head of the mounting bolt 11 through a hole, and the rear end is snapped into the screw hole 10 through a snap-fit ​​head 8012, thereby achieving snap-fit ​​and maintaining stability by utilizing its own strength to achieve shock absorption. Example

[0037] The difference between this embodiment and embodiment three is that the can lid shock absorber 8 is a flexible can lid shock absorber 802, made of rubber or silicone. Its inner shape matches the shape of the can lid 16, and it has two mounting screw holes 8021 for bolt installation. The can lid 16 is installed with mounting bolt two 12. The outer side of the screw head of the mounting bolt two 12 has a bolt stepped groove 13, and the mounting screw hole 8021 has a matching screw hole stepped groove 8022. The flexible can lid shock absorber 802 is installed on the can lid 16 by mounting bolt two 12.

[0038] The shock absorber is made of flexible material, which has a stronger shock absorption effect. However, due to its high flexibility, it cannot be snapped together for installation. Therefore, by using the stepped groove and the mounting bolts of the can cover 16 itself, it can be pressed tightly during installation. The structure is simple, stable and efficient.

[0039] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.

[0040] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
