Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile air conditioner compressor, specifically relates to a valve plate mounting assembly of automobile air conditioner compressor. BACKGROUND

[0002] In the automobile air conditioning system, the compressor is the core component, and its performance directly affects the refrigeration effect and stability of the air conditioner. As a key component of the compressor, the valve plate bears the important responsibility of controlling the flow and pressure of the refrigerant, and its stability is crucial to the normal operation of the compressor.

[0003] The traditional automobile air conditioner compressor valve plate installation method has many problems. During installation, the valve plate is usually manually aligned with the installation position of the compressor shell and the rear cover, and then fastened with bolts. This manual alignment method relies heavily on the technical level and experience of the operator, and the installation efficiency is low. Moreover, in actual operation, it is difficult to ensure that the valve plate is installed accurately, and small installation deviations may cause uneven stress on the valve plate during compressor operation.

[0004] When the compressor is running at high speed, the valve plate is subjected to large vibration and impact force. In the prior art, the valve plate relies only on the fastening force of the bolt to maintain its position, and lacks additional limiting measures. This makes the valve plate prone to gradual displacement under the action of long-term vibration, which affects its control effect on the refrigerant, reduces the refrigeration efficiency of the compressor, and even causes compressor failure, shortening its service life.

[0005] Therefore, we propose a valve plate mounting assembly for an automobile air conditioner compressor, which can prevent unnecessary displacement of the valve plate during compressor operation due to vibration and other reasons, and ensure stable installation of the valve plate between the compressor shell and the rear cover. Utility model content

[0006] The utility model aims at providing a valve plate mounting assembly for an automobile air conditioner compressor, which can prevent unnecessary displacement of the valve plate during compressor operation due to vibration and other reasons, and ensure stable installation of the valve plate between the compressor shell and the rear cover.

[0007] The technical scheme adopted by the utility model is as follows:

[0008] A valve plate mounting assembly for an automobile air conditioner compressor, comprising a compressor shell and a rear cover, wherein the compressor shell and the rear cover are provided with first threaded holes, and the first threaded holes are provided with bolts, and the bolts are provided with magnetic sleeves.

[0009] A valve plate is installed between the compressor housing and the rear cover, and a connecting rod is provided on one side of the compressor housing. An elastic component is provided on the connecting rod, and a magnetic block that repels the magnetic sleeve is provided on the elastic component. A connecting hole is provided on the valve plate for inserting the connecting rod and the magnetic block.

[0010] Furthermore, the length of the connecting rod matches the length of the connecting hole.

[0011] Furthermore, a second threaded hole is provided on the valve plate, and the second threaded hole corresponds to the position of the first threaded hole.

[0012] Furthermore, the elastic component includes a groove formed on the connecting rod, a fixed shaft is provided inside the groove, a slider and a spring are sleeved on the fixed shaft, the bottom of the slider is connected to the spring, and one side of the slider is connected to the magnetic block.

[0013] Furthermore, the slider matches the groove.

[0014] Furthermore, the magnetic sleeve is threadedly connected to the bolt.

[0015] Furthermore, the diameter of the connecting rod is larger than the diameter of the magnetic block.

[0016] The technical effects achieved by this utility model are as follows:

[0017] First, when installing the valve plate, align the connecting rod with the connecting hole, and then install the valve plate on one side of the compressor housing. At this point, align the first threaded hole on the rear cover with the first threaded hole on the compressor housing, and insert the bolt to fix it. When the thread is in place, the magnetic sleeve and the magnetic block correspond to each other and generate a repulsive force, which causes the magnetic block to move through the elastic component. This causes the magnetic block to deviate from the center position of the connecting hole, thus forming a limit and preventing the valve plate from unnecessary displacement due to vibration or other reasons during compressor operation, ensuring the stable installation of the valve plate between the compressor housing and the rear cover.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A mounting assembly for a valve plate 6 of an automotive air conditioning compressor includes a compressor housing 1 and a rear cover 2. Both the compressor housing 1 and the rear cover 2 are provided with a first threaded hole 3. A bolt 4 is provided inside the first threaded hole 3, and a magnetic sleeve 5 is provided on the bolt 4.

[0026] A valve plate 6 is installed between the compressor housing 1 and the rear cover 2, and a connecting rod 7 is provided on one side of the compressor. An elastic component is provided on the connecting rod 7, and a magnetic block 8 that repels the magnetic sleeve 5 is provided on the elastic component. A connecting hole 9 is provided on the valve plate 6 so that the connecting rod 7 and the magnetic block 8 can be inserted.

[0027] The length of the connecting rod 7 is matched with the length of the connecting hole 9. This arrangement ensures that when the connecting rod 7 enters the connecting hole 9, the magnetic block 8 is in close contact with the side of the compressor housing 1 during displacement, preventing gaps that could cause wobbling.

[0028] The magnetic sleeve 5 and the magnetic block 8 are positioned to correspond to each other. The purpose of this arrangement is that when the bolt 4 moves to fix the position, the magnetic sleeve 5 is positioned to correspond to the magnetic block 8, thereby generating a repulsive force.

[0029] The elastic component includes a groove 10 formed on the connecting rod 7. A fixed shaft 11 is provided inside the groove 10. A slider 12 and a spring 13 are sleeved on the fixed shaft 11. The bottom of the slider 12 is connected to the spring 13, and one side of the slider 12 is connected to the magnetic block 8.

[0030] When a repulsive force is generated, the magnetic block 8 drives the slider 12 to move on the fixed shaft 11, thereby offsetting the position of the connecting hole 9 to form a limit.

[0031] The slider 12 is matched with the slide groove 10. This arrangement allows the slider 12 to move smoothly inside the slide groove 10 without jamming.

[0032] The magnetic sleeve 5 is threadedly connected to the bolt 4. This arrangement allows the magnetic sleeve 5 to change position to adapt to different valve plates 6.

[0033] The diameter of the connecting rod 7 is larger than the diameter of the magnetic block 8, so that the connecting rod 7 and the magnetic block 8 can pass through the connecting hole 9.

[0034] A second threaded hole is provided on the valve plate 6, through which the bolt 4 can be passed for fixing.

[0035] The working principle of this utility model is as follows: First, when installing the valve plate 6, align the connecting rod 7 with the connecting hole 9, and then install the valve plate 6 on one side of the compressor housing 1. At this time, align the first threaded hole 3 on the rear cover 2 with the first threaded hole 3 on the compressor housing 1, and insert the bolt 4 for fixing. When the bolt 4 is in place, the magnetic sleeve 5 and the magnetic block 8 generate a repulsive force, which causes the magnetic block 8 to move through the elastic component, causing the magnetic block 8 to deviate from the center position of the connecting hole 9, thereby forming a limit and preventing the valve plate 6 from unnecessary displacement due to vibration or other reasons during compressor operation, thus ensuring the stable installation of the valve plate 6 between the compressor housing 1 and the rear cover 2.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
