In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described herein, and therefore the scope of the present utility model is not limited to the specific embodiments disclosed below.

A compressor 100, a refrigeration apparatus, and a vehicle provided according to some embodiments of the present utility model are described below with reference to fig. 1 to 12.

In one embodiment according to the present utility model, as shown in fig. 1, 2, 3, 4, 5, 6, 7, 8 and 9, a compressor 100 is proposed, the compressor 100 comprising: a housing 110, the housing 110 being provided with a compression chamber 112 and an exhaust port 113 in communication; the limiting piece 120 is arranged in the shell 110; the exhaust valve 130 is located at the outer side of the limiting piece 120, the exhaust valve 130 comprises a first valve body 131 and a second valve body 132 which are connected, the first valve body 131 is located at the exhaust port 113 and is spaced from the outer wall of the limiting piece 120, the first valve body 131 can open or close the exhaust port 113, the second valve body 132 comprises a bending part 1321 bending towards one side of the limiting piece 120, and when the first valve body 131 opens the exhaust port 113, at least one part of the bending part 1321 is attached to the outer wall of the limiting piece 120.

The compressor 100 provided by the embodiment of the utility model comprises a shell 110, a limiting piece 120 and an exhaust valve 130, wherein the shell 110 is provided with a compression cavity 112 and an exhaust port 113, and the compression cavity 112 is communicated with the exhaust port 113. It can be appreciated that the gas in the compression chamber 112 is discharged through the discharge port 113.

The exhaust valve 130 includes a first valve body 131 and a second valve body 132, wherein the first valve body 131 and the second valve body 132 are connected. The first valve body 131 is located at the exhaust port 113, specifically, the first valve body 131 is located at a side of the exhaust port 113 facing away from the compression chamber 112, and the first valve body 131 is movable with respect to the exhaust port 113 to open or close the exhaust port 113. It can be understood that the exhaust port 113 can be opened when the first valve body 131 moves in a direction away from the exhaust port 113, and accordingly, the exhaust port 113 can be closed when the first valve body 131 moves in a direction toward the exhaust port 113.

The exhaust valve 130 is located at the outer side of the limiting member 120, and the first valve body 131 of the exhaust valve 130 has a distance from the outer wall of the limiting member 120, so that when the compression chamber 112 of the compressor 100 is exhausted, gas impacts the first valve body 131 through the exhaust port 113, so that the first valve body 131 moves towards a direction away from the exhaust port 113, namely, the first valve body 131 moves towards one side close to the limiting member 120, and contacts with the limiting member 120 when moving for a certain distance, so that the limiting member 120 limits the first valve body 131, the first valve body 131 is prevented from moving continuously, and further the problem that the service life of the exhaust valve 130 is reduced due to overlarge bending stress of the exhaust valve 130 can be avoided.

The second valve body 132 includes a bending portion 1321, specifically, the bending portion 1321 is bent toward the side where the stopper 120 is located. When the first valve body 131 opens the exhaust port 113 to exhaust air, at least a portion of the bending portion 1321 is attached to the outer wall of the stopper 120, that is, a side surface of the bending portion 1321 facing the stopper 120 is attached to the outer wall of the stopper 120. Therefore, when the first valve body 131 moves to one side of the limiting member 120 to open the exhaust port 113, the rigidity of the exhaust valve 130 can be rapidly increased by attaching the bending part 1321 to the outer wall of the limiting member 120, and when the exhaust port 113 is opened, the rigidity of the exhaust valve 130 is non-linearly increased, that is, the greater the distance that the first valve body 131 moves to the side of the limiting member 120 is, the greater the opening rigidity is, so that the problem that the high frequency and the low frequency of the compressor 100 cannot be considered due to the fact that the rigidity of the flat reed valve is a fixed value in the related art is solved, and the efficiency of the compressor 100 is ensured.

In addition, by the cooperation of the exhaust valve 130 and the stopper 120, the rigidity of the exhaust valve 130 is increased when the exhaust port 113 is opened, and thus the rigidity of the exhaust valve 130 is rapidly increased while avoiding an excessive bending stress of the exhaust valve 130. The structural design is simple, and the operation is convenient. And there is no need to provide a lift limiter structure in the related art, so that the structure of the compressor 100 can be simplified, and the production cost of the compressor 100 can be reduced.

In practical applications, the second valve body 132 may be a bent portion 1321, or may be partially a bent portion 1321, and the first valve body 131 may be a straight valve body or an arc valve body, which may be specifically set according to practical needs.

It should be noted that, the first valve body 131 and the second valve body 132 are an integral structure, and it can be understood that the integral structure has good mechanical properties, so that the connection strength between the first valve body 131 and the second valve body 132 can be improved, and the service life of the exhaust valve 130 is ensured. In addition, the integrated structure facilitates mass production of the discharge valve 130, and thus the production cost of the compressor 100 can be further reduced.

In addition, the cross-sectional shape of the limiting member 120 may be circular or spline curved surface, and may be specifically set according to actual needs. Specifically, when the exhaust port 113 is opened to exhaust, the exhaust valve 130 is stuck around the outer wall of the stopper 120, thereby rapidly increasing the rigidity of the exhaust valve 130.

In practical applications, the cross-sectional shape of the bending portion 1321 is a circular arc, or a plurality of circular arcs are connected, or an elliptical arc, or a spline curve. The setting can be specifically performed according to actual needs.

Wherein, the exhaust valve 130 may be rectangular, T-shaped or I-shaped after being unfolded.

As shown in fig. 1, 2 and 7, further, based on the above embodiment, a side surface of the bending portion 1321, which is close to the limiting member 120, includes a first arc surface 133; the outer wall of the limiting member 120 includes a second arc surface 121, and when the first valve body 131 opens the exhaust port 113, at least a portion of the first arc surface 133 is in contact with the second arc surface 121.

In this embodiment, a side surface of the bent portion 1321 near the limiting member 120 includes a first arc surface 133, an outer wall of the limiting member 120 includes a second arc surface 121, when the exhaust port 113 is opened to exhaust, at least a portion of the first arc surface 133 is attached to the second arc surface 121, that is, when the first valve body 131 moves to the side of the limiting member 120, the first valve body 131 and the second valve body 132 are attached around the outer wall of the limiting member 120, so that the rigidity of the exhaust valve 130 is rapidly increased, and the rigidity of the exhaust valve 130 is increased in a nonlinear manner, that is, the greater the distance the first valve body 131 moves to the side of the limiting member 120, the greater the opening rigidity, so that the problem that the high frequency and the low frequency of the compressor 100 cannot be considered due to the fact that the rigidity of the flat reed valve is a fixed value in the related art is solved, and the efficiency of the compressor 100 is ensured.

Moreover, the structure is simple in design and convenient to operate. And there is no need to provide a lift limiter structure in the related art, so that the structure of the compressor 100 can be simplified, and the production cost of the compressor 100 can be reduced.

Further, by the first curved surface 133 being in contact with the second curved surface 121, the rigidity of the exhaust valve 130 can be further made nonlinear and rapidly increased. And through setting up first arcwall face 133 and second arcwall face 121, can also reduce the occupation space of discharge valve 130 and locating part 120, and then make the compact structure of compressor 100.

Further, the radius of curvature of the first curved surface 133 is greater than or equal to the radius of curvature of the second curved surface 121.

In this embodiment, the radius of curvature of the first arcuate surface 133 is greater than or equal to the radius of curvature of the second arcuate surface 121, so that the exhaust valve 130 can be ensured to be wound along the outer wall of the limiting member 120 during the process of opening the exhaust port 113 by the first valve body 131, so that the rigidity of the exhaust valve 130 is rapidly increased, and the rigidity of the exhaust valve 130 is increased in a nonlinear manner, i.e. the greater the distance from the first valve body 131 to the side of the limiting member 120, the greater the opening rigidity, so that the problem that the high and low frequency of the compressor 100 cannot be considered due to the fact that the rigidity of the flat reed valve is a fixed value in the related art is solved, and the efficiency of the compressor 100 is ensured.

Moreover, the structure is simple in design and convenient to operate. And there is no need to provide a lift limiter structure in the related art, so that the structure of the compressor 100 can be simplified, and the production cost of the compressor 100 can be reduced.

In this embodiment, the housing 110 is provided with a mounting wall, specifically, a mounting space is formed between the mounting wall and an outer wall of the stopper 120, and the exhaust valve 130 is located in the mounting space. That is, the outer wall of the vent valve 130 is disposed adjacent to the mounting wall, and the inner wall of the vent valve 130 is disposed adjacent to the stopper 120.

The installation wall includes the third arced surface, and when the first valve body 131 closed the gas vent 113, at least a portion of the portion 1321 of bending is laminated mutually with the third arced surface, specifically, the portion 1321 of bending deviates from the side of locating part 120 and laminates mutually with the third arced surface to can ensure that the first valve body 131 carries out effective sealing to the gas vent 113, and then ensure the stability and the reliability of compressor 100 operation.

In practical application, the radius of the third arc surface is smaller than or equal to the radius of the first arc surface 133, so that the installation wall can have pressure on the exhaust valve 130 towards the side where the limiting member 120 is located, even if the exhaust valve 130 has a certain compression, the sealing effect is good. And the sealability of the exhaust valve 130 to the exhaust port 113 can be improved as compared to the related art in which a flat reed valve is used and sealed with a metal plane.

Further, the radius of curvature of the third curved surface is smaller than or equal to the radius of curvature of the first curved surface 133 on the basis of the above-described embodiment.

In this embodiment, the radius of curvature of the third arcuate surface is smaller than or equal to the radius of curvature of the first arcuate surface 133, so that the mounting wall can have a pressure on the exhaust valve 130 toward the side of the stopper 120, even if the exhaust valve 130 has a certain compression, the sealing effect is good. And the sealability of the exhaust valve 130 to the exhaust port 113 can be improved as compared to the related art in which a flat reed valve is used and sealed with a metal plane.

As shown in fig. 1, 2, 3, 4, 5, 6, 7, 8 and 9, further, a side surface of the first valve body 131 facing the exhaust port 113 is a first plane 134 according to the above embodiment; and/or the second valve body 132 further comprises an installation part 1322, the installation part 1322 is connected with the bending part 1321, a side surface of the installation part 1322, which is away from the limiting piece 120, is a second plane 135, and the installation part 1322 is connected with the housing 110.

In this embodiment, a side surface of the first valve body 131 facing the exhaust port 113 is a first plane 134, that is, the exhaust port 113 is sealed by the first plane 134 of the first valve body 131, so that the sealing effect on the exhaust port 113 is improved.

In addition, it will be appreciated that the side of the first valve body 131 facing the exhaust port 113 is generally planar at the position of the exhaust port 113 in the housing 110, and the side facing the exhaust port 113 is configured to be planar, so as to adapt to the structure of the position of the exhaust port 113 in the housing 110, and ensure effective sealing of the exhaust port 113.

The second valve body 132 further includes an installation portion 1322, the installation portion 1322 is connected with the bending portion 1321, and a side surface of the installation portion 1322, which faces away from the limiting member 120, is a second plane 135, the installation portion 1322 is connected with the housing 110, that is, one end, which faces away from the first valve body 131, of the second valve body 132 is set to be the installation portion 1322, and the installation portion 1322 is further fixed with the housing 110, so that the installation stability of the exhaust valve 130 is improved, and effective control of the exhaust valve 130 on and off the exhaust port 113 is ensured.

Further, a side surface of the mounting portion 1322 facing away from the limiting member 120 is the second plane 135, that is, a side surface of the mounting portion 1322 facing away from the limiting member 120 is set to be a plane, so that the mounting portion 1322 and the housing 110 can be conveniently connected and fixed.

In a specific embodiment, further, a side of the bent portion 1321 facing away from the stopper 120 includes a fourth arcuate surface 136, and the fourth arcuate surface 136 is tangential to the first plane 134 and/or the second plane 135.

In this embodiment, a side of the bend 1321 facing away from the stop 120 includes a fourth arcuate surface 136, and in particular, the fourth arcuate surface 136 is tangential to the first plane 134 and/or the second plane 135, thereby enabling an extended service life of the exhaust valve 130.

It can be understood that the bending portion 1321 is an arc-shaped segment, and the mounting portion 1322 or the first valve body 131 is a straight segment, so that the connection between the first valve body 131 and the bending portion 1321 or the connection between the bending portion 1321 and the mounting portion 1322 has a large stress, and the exhaust valve 130 is easily damaged after repeated bending and long-term use. By making the fourth arc surface 136 tangent to the first plane 134 and/or the second plane 135, the connection between the bending portion 1321 and the mounting portion 1322 or the first valve body 131 can be smooth and excessive, so that the stress at the connection is reduced, and the service life of the exhaust valve 130 is prolonged.

Specifically, when the first valve body 131 opens the exhaust port 113 to exhaust air, at least a portion of the bending portion 1321 is attached to the outer wall of the stopper 120, that is, a side surface of the bending portion 1321 facing the stopper 120 is attached to the outer wall of the stopper 120. Therefore, when the first valve body 131 moves to one side of the limiting member 120 to open the exhaust port 113, the rigidity of the exhaust valve 130 can be rapidly increased by attaching the bending part 1321 to the outer wall of the limiting member 120, and when the exhaust port 113 is opened, the rigidity of the exhaust valve 130 is non-linearly increased, that is, the greater the distance that the first valve body 131 moves to the side of the limiting member 120 is, the greater the opening rigidity is, so that the problem that the high frequency and the low frequency of the compressor 100 cannot be considered due to the fact that the rigidity of the flat reed valve is a fixed value in the related art is solved, and the efficiency of the compressor 100 is ensured.

In this embodiment, it is defined that the case 110 includes the case body 111 and the blocking member 114, specifically, the case body 111 is provided with the mounting port 140, the mounting port 140 can communicate with the exhaust port 113, and by providing the mounting port 140, the mounting and dismounting of the exhaust valve 130 can be performed through the mounting port 140.

The sealing member 114 is positioned at the mounting port 140, and since the mounting port 140 communicates with the exhaust port 113, by disposing the sealing member 114 at the mounting port 140 and sealing-connecting with the casing body 111, it is possible to prevent leakage of gas through the mounting port 140 and secure the efficiency of the compressor 100.

The limiting piece 120 is disposed on the shell body 111 or the blocking piece 114, that is, the limiting piece 120 can be integrally formed with the shell body 111 or the blocking piece 114, and specifically can be disposed according to actual needs. Of course, the limiting member 120 may be a separate member connected to the case body 111 or the blocking member 114.

In practical applications, external threads may be disposed on the outer wall of the plugging member 114, and internal threads may be disposed on the inner wall of the mounting opening 140, so as to realize the sealing connection between the plugging member 114 and the shell body 111 through threaded engagement. In addition, a seal may be provided at the junction of the closure 114 and the housing body 111 to ensure that gas cannot leak from the mounting port 140. The blocking member 114 may be in an interference fit with the case body 111, or may be sealed by welding or the like.

As shown in fig. 11, further, the side of the vent valve 130 facing the mounting opening 140 abuts against the side of the blocking member 114 facing the vent valve 130.

In this embodiment, the side of the exhaust valve 130 facing the mounting opening 140 and the side of the blocking member 114 facing the exhaust valve 130 are abutted, so as to limit the exhaust valve 130, prevent the exhaust valve 130 from moving to the side where the blocking member 114 is located in the repeated bending process, ensure that the exhaust valve 130 can effectively open or close the exhaust port 113, and further ensure the stability and reliability of the operation process of the compressor 100.

In this embodiment, a limiting surface 150 is disposed on a side of the shell body 111 facing the plugging member 114, and a side of the exhaust valve 130 facing away from the mounting opening 140 abuts against the limiting surface 150, so that the exhaust valve 130 is further limited, movement to a side facing away from the plugging member 114 in the repeated bending process is prevented, the exhaust valve 130 is ensured to be capable of effectively opening or closing the exhaust port 113, and stability and reliability in the operation process of the compressor 100 are further ensured.

Specifically, when the first valve body 131 opens the exhaust port 113 to exhaust air, at least a portion of the bending portion 1321 is attached to the outer wall of the stopper 120, that is, a side surface of the bending portion 1321 facing the stopper 120 is attached to the outer wall of the stopper 120. Therefore, when the first valve body 131 moves to one side of the limiting member 120 to open the exhaust port 113, the rigidity of the exhaust valve 130 can be rapidly increased by attaching the bending part 1321 to the outer wall of the limiting member 120, and when the exhaust port 113 is opened, the rigidity of the exhaust valve 130 is non-linearly increased, that is, the greater the distance that the first valve body 131 moves to the side of the limiting member 120 is, the greater the opening rigidity is, so that the problem that the high frequency and the low frequency of the compressor 100 cannot be considered due to the fact that the rigidity of the flat reed valve is a fixed value in the related art is solved, and the efficiency of the compressor 100 is ensured.

In addition, by the cooperation of the exhaust valve 130 and the stopper 120, the rigidity of the exhaust valve 130 is increased when the exhaust port 113 is opened, and thus the rigidity of the exhaust valve 130 is rapidly increased while avoiding an excessive bending stress of the exhaust valve 130. The structural design is simple, and the operation is convenient. And there is no need to provide a lift limiter structure in the related art, so that the structure of the compressor 100 can be simplified, and the production cost of the compressor 100 can be reduced.

Further, as shown in fig. 11, in the above embodiment, the plugging member 114 is provided with a relief space 160 and a relief hole 170 which are communicated, and the relief space 160 can be communicated with the exhaust port 113; the compressor 100 further includes an air outlet 180, the air outlet 180 is disposed on the shell body 111, and the air outlet 180 is communicated with the avoidance hole 170.

In this embodiment, the blocking member 114 is provided with an escape space 160 and an escape hole 170, specifically, the escape space 160 communicates with the escape hole 170, and the escape hole 170 communicates with an air outlet 180 provided on the case body 111. It can be understood that when the compression chamber 112 is exhausted, the first valve body 131 opens the exhaust port 113, and the gas is exhausted from the exhaust port 113, through the avoidance space 160 and the avoidance hole 170, and finally exhausted through the gas outlet 180, that is, an exhaust channel of the gas is formed through the exhaust port 113, the avoidance space 160, the avoidance hole 170 and the gas outlet 180, so that rapid exhaust of the gas is realized.

Specifically, when the first valve body 131 opens the exhaust port 113 to exhaust air, at least a portion of the bending portion 1321 is attached to the outer wall of the stopper 120, that is, a side surface of the bending portion 1321 facing the stopper 120 is attached to the outer wall of the stopper 120. Therefore, when the first valve body 131 moves to one side of the limiting member 120 to open the exhaust port 113, the rigidity of the exhaust valve 130 can be rapidly increased by attaching the bending part 1321 to the outer wall of the limiting member 120, and when the exhaust port 113 is opened, the rigidity of the exhaust valve 130 is non-linearly increased, that is, the greater the distance that the first valve body 131 moves to the side of the limiting member 120 is, the greater the opening rigidity is, so that the problem that the high frequency and the low frequency of the compressor 100 cannot be considered due to the fact that the rigidity of the flat reed valve is a fixed value in the related art is solved, and the efficiency of the compressor 100 is ensured.

In addition, by the cooperation of the exhaust valve 130 and the stopper 120, the rigidity of the exhaust valve 130 is increased when the exhaust port 113 is opened, and thus the rigidity of the exhaust valve 130 is rapidly increased while avoiding an excessive bending stress of the exhaust valve 130. The structural design is simple, and the operation is convenient. And there is no need to provide a lift limiter structure in the related art, so that the structure of the compressor 100 can be simplified, and the production cost of the compressor 100 can be reduced.

In one particular embodiment, further, the average thickness d of the vent valve 130 satisfies 0.076 mm.ltoreq.d.ltoreq.0.6 mm.

In this embodiment, the average thickness of the discharge valve 130 is defined to be between 0.076mm and 0.6mm, and it can be understood that if the average thickness of the discharge valve 130 is too thick, the rigidity of the corresponding discharge valve 130 is large, and it is not ensured that the first valve body 131 can rapidly open the discharge port 113 to discharge gas when the gas in the compression chamber 112 impinges on the first valve body 131. If the average thickness of the exhaust valve 130 is too thin, breakage or the like is likely to occur in the exhaust valve 130 during repeated bending, and the service life of the exhaust valve 130 is reduced.

By limiting the average thickness of the exhaust valve 130 to between 0.076mm and 0.6mm, the service life of the exhaust valve 130 can be ensured while ensuring the rigidity of the exhaust valve 130.
