Description

Technical Field

[0001] This invention relates to the field of air conditioning compressor technology, and particularly to a pressure relief valve guide device and an air conditioning compressor and automobile using the same. Background Technology

[0002] As a pressure relief device for the air conditioning compressor, the pressure relief valve is responsible for releasing the refrigerant inside the compressor under extreme failure conditions, thereby reducing the internal pressure of the compressor and protecting the compressor and the front-end gear system of the engine.

[0003] In existing technologies, pressure relief valves discharge pressure in a direct direction, meaning the high-temperature, high-pressure refrigerant inside the compressor is sprayed directly out along the valve's axis. Since the refrigerant inside the compressor is high-temperature, high-pressure, and flammable, to prevent a fire caused by the high-temperature, high-pressure refrigerant spraying onto high-temperature components in the engine compartment, the pressure relief valve's spray direction cannot be directly aimed at these components, such as the turbocharger, exhaust pipe, and catalytic converter. If design checks reveal that the pressure relief valve's discharge direction is directly aimed at high-temperature components, given the existing valve structure, the only solution is to change the valve's position on the compressor, or even adjust the compressor's placement on the engine. This involves modifications to the compressor's internal flow path structure, and in severe cases, major adjustments to the engine compartment and engine layout. This process is lengthy, costly, and makes it difficult to standardize the compressor across a single platform. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a pressure relief valve guiding device, which aims to solve the technical problem that in the prior art, the pressure relief valve has a straight discharge direction, and if the spray direction of the pressure relief valve is directly facing the high-temperature components in the engine room, it is extremely easy to cause a fire.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] A pressure relief valve guiding device includes a guide cover disposed at one end of the vent of the pressure relief valve. The guide cover has a receiving space for gas flow, and the receiving space includes a gas outlet. The gas outlet is arranged at an angle to the vent. The pressure relief valve guiding device also includes a guiding mechanism, which includes a guiding channel, a support block, and a rotating mechanism connecting the guiding channel and the support block. The guiding channel is disposed on the outside of the guide cover near the gas outlet, and the support block is located inside the guide cover. The guiding mechanism also includes a telescopic mechanism, through which the support block slides inside the guide cover to move the guiding channel closer to or away from the guide cover. The guiding channel rotates relative to the support block through the rotating mechanism to form an angle between the guiding channel and the gas outlet.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0008] By installing a deflector at the vent of the pressure relief valve, with the outlet of the deflector at an angle to the vent, the refrigerant discharged from the pressure relief valve can be discharged at a different angle, preventing the refrigerant from spraying directly onto high-temperature components in the engine compartment along the axial direction of the pressure relief valve and causing a fire. Furthermore, by providing a guide channel near the outlet to guide the specific flow of the refrigerant, the guide channel can be extended or rotated by a telescopic and rotating mechanism. The specific orientation of the guide channel can be adjusted according to the actual position of the pressure relief valve on the vehicle, guiding the refrigerant to spray in a specific direction. This avoids the need to adjust the arrangement of the compressor on the engine, and this guiding device can be mass-produced on a platform.

[0009] Furthermore, the support block slides inside the guide cover in a direction parallel to the opening of the air outlet.

[0010] Furthermore, the telescopic mechanism includes a lead screw and an adjusting knob. The lead screw is threaded to the end of the support block away from the guide channel. The adjusting knob is located at the end of the lead screw away from the support block and is exposed outside the guide cover. Rotating the adjusting knob drives the lead screw to rotate, so that the support block moves telescopically along the axial direction of the lead screw.

[0011] Furthermore, the guide channel includes a flow section and an enclosure section. The flow section is parallel to the gas outlet section and is used to guide the flow of gas. The enclosure section is located on both sides of the flow section in the radial direction and is used to restrict the diffusion of gas.

[0012] Furthermore, the rotating mechanism includes a hinge assembly, which includes a first rotating plate fixedly connected to the guide channel, a second rotating plate fixedly connected to the support block, and a connecting shaft fixedly connected to the second rotating plate. The end of the connecting shaft extends into the first rotating plate, and the first rotating plate is rotatably connected to the second rotating plate through the connecting shaft.

[0013] Furthermore, the rotating mechanism also includes two locking components, which are disposed opposite to each other on both sides of the hinge assembly to restrict the rotation of the hinge assembly. Each locking component includes a piston rod, a sleeve, and a compression spring. The sleeve is sleeved outside the piston rod. Inside the sleeve, the piston rod is connected to the sleeve via the compression spring. A stop member is provided on the outer cylindrical surface of the piston rod. A first sliding groove is provided on the outer cylindrical surface of the sleeve, corresponding to the moving direction of the stop member. An insertion port is provided at one end of the hinge assembly near the locking component, and a second sliding groove is provided in the insertion port corresponding to the sliding direction of the stop member. A receiving groove is provided inside the hinge assembly. The cross-sectional size of the receiving groove is larger than that of the insertion port. The piston rod pushes the sleeve into the insertion port and touches the blocking part inside the hinge assembly, so that the stop member enters the receiving groove along the first sliding groove and the second sliding groove. Rotating the locking component moves the stop member away from the second sliding groove, so that the stop member is pressed against the side of the receiving groove near the insertion port by the rebound force of the compression spring.

[0014] Furthermore, the side of the abutment member away from the hinge assembly is provided with anti-slip texture, and the side of the piston rod away from the compression spring is provided with a pressing part.

[0015] Furthermore, the pressure relief valve guide mechanism also includes a clamp, which is sleeved on the end of the flow guide away from the pressure relief valve. Multiple support arms extend from the surface of the clamp toward the end of the pressure relief valve, and the free end of the support arm is trapezoidal. A clamping arm is rotatably connected to the free end of the support arm. The clamping arm includes a rotating groove with the same shape as the free end of the support arm and a support foot near the end of the flow guide. The clamp fixes the flow guide to the vent of the pressure relief valve. The clamping arm rotates relative to the support arm so that the clamping arm engages with the surface of the pressure relief valve.

[0016] The present invention also provides an air conditioning compressor, including the pressure relief valve guide device as described above.

[0017] The present invention also provides an automobile, including an air conditioning compressor as described above. Attached Figure Description

[0029] The following detailed description, in conjunction with the accompanying drawings, will further illustrate the present invention. Detailed Implementation

[0030] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0031] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please see Figures 1 to 9 The diagram illustrates a pressure relief valve guide device according to an embodiment of the present invention, used to change the angle at which refrigerant is ejected from the pressure relief valve 40. The pressure relief valve guide device includes a guide cover 10 disposed at one end of the vent of the pressure relief valve 40. The outer shell of the guide cover 10 is hexagonal, and the guide cover 10 has a accommodating space for gas flow. The accommodating space includes a gas storage section 15 and a gas outlet section 16. The gas storage section 15 has a circular cross-section, and the gas outlet section 16 opens from the lower end of the gas storage section 15 and transitions smoothly. This design structure allows the refrigerant to flow smoothly within the guide cover and better flow out of the gas outlet section 16. The gas outlet section 16 is set at an angle to the vent. The pressure relief valve guide device also includes a guide mechanism 20, which is disposed close to the gas outlet section 16 and is used to guide the flow direction of the gas discharged from the gas outlet section 16.

[0034] Understandably, by setting a deflector at the vent of the pressure relief valve 40, with the outlet 16 of the deflector at an angle to the vent, the refrigerant discharged from the pressure relief valve 40 can be discharged at a different angle, preventing the refrigerant from being sprayed directly onto the high-temperature components in the engine compartment along the axial direction of the pressure relief valve 40 and causing a fire. Furthermore, by providing a guide mechanism 20 near the outlet 16 to guide the specific flow of the refrigerant, the refrigerant can be guided to spray in a specific direction according to the actual position of the pressure relief valve 40 on the vehicle, avoiding the need to adjust the arrangement of the compressor on the engine. Moreover, this guide device can be mass-produced on a platform.

[0035] Furthermore, the pressure relief valve guide device also includes a telescopic mechanism. The telescopic mechanism is located at the end of the guide mechanism 20 away from the opening of the air outlet 16. The guide mechanism 20 extends or retracts through the end of the telescopic mechanism parallel to the opening of the air outlet 16. The telescopic mechanism includes a lead screw 23 and an adjusting knob 24. The lead screw 23 is threadedly connected to the end of the guide mechanism 20 away from the air outlet 16. The adjusting knob 24 is located at the end of the lead screw 23 away from the guide mechanism 20, and the adjusting knob 24 is exposed outside the guide cover 10. Rotating the adjusting knob 24 drives the lead screw 23 to rotate, so that the guide mechanism 20 moves telescopically along the axial direction of the lead screw 23.

[0036] Specifically, the guiding mechanism 20 includes a guiding channel 21 and a support block 22. The guiding channel 21 is parallel to the air outlet 16, and the support block 22 is located above the guiding channel 21. The lead screw 23 is inserted into the support block 22. By rotating the adjusting knob 24, the support block 22 can drive the guiding channel 21 to slide outward to adjust the length of the guiding channel 21. In special cases, such as when the pressure relief valve 40 is located close to other high-temperature components in the engine room, the length of the guiding channel 21 can be adjusted to avoid these high-temperature components.

[0037] Preferably, the guide channel 21 includes a flow section and an enclosure section. The flow section is parallel to the gas outlet 16 and is used to guide the flow of gas. The enclosure section is located on both sides of the flow section in the radial direction and is used to restrict the diffusion of gas. The enclosure section is located on the side of the flow section near the pressure relief valve 40.

[0038] Understandably, since the refrigerant is sprayed at a relatively high pressure, enclosing portions are provided on both sides of the flow section. When the refrigerant is sprayed along the flow section, it can prevent the refrigerant from escaping to both sides due to excessive pressure. In addition, inside the flow guide, a sliding groove can be provided along the moving direction of the enclosing portion to make the flow guide channel more stable when it expands and contracts.

[0039] Furthermore, the pressure relief valve guide device also includes a rotating mechanism, which includes a hinge assembly 25 connecting the guide channel 21 and the support block 22. The guide channel 21 extends out of the guide cover 10 and rotates through the hinge assembly 25 so that the guide channel 21 forms an angle with the air outlet 16.

[0040] Understandably, the guide channel 21 is rotated relative to the air outlet 16 by the aforementioned rotating mechanism to accommodate different vehicle engine compartment layouts and avoid high-temperature components.

[0041] Specifically, the rotating mechanism includes a hinge assembly 25, which includes a first rotating plate 253 fixedly connected to the guide channel 21, a second rotating plate 254 fixedly connected to the support block 22, and a connecting shaft (not shown in the figure) fixedly connected to the second rotating plate 254. The end of the connecting shaft extends into the first rotating plate 253, and the first rotating plate 253 is rotatably connected to the second rotating plate 254 through the connecting shaft.

[0042] The rotating mechanism further includes two locking components 26, which are disposed opposite to each other on both sides of the hinge assembly 25 to restrict the rotation of the hinge assembly 25. Each locking component 26 includes a piston rod 262, a sleeve 261, and a compression spring 268. The sleeve 261 is sleeved outside the piston rod 262. Inside the sleeve 261, the piston rod 262 is connected to the sleeve 261 via the compression spring 268. A stop member 264 is provided on the outer cylindrical surface of the piston rod 262. A first sliding groove 265 is provided on the outer cylindrical surface of the sleeve 261 in the direction corresponding to the movement of the stop member 264. The hinge assembly 25 has an insertion port 252 at one end near the locking component 26, and the insertion port 252 is... The opening 252 has a second sliding groove 266 corresponding to the sliding direction of the abutment 264. The hinge assembly 25 has a receiving groove 251 inside. The cross-sectional dimension of the receiving groove 251 is larger than that of the insertion opening 252. The piston rod 262 pushes the sleeve 261 into the insertion opening 252 and touches the blocking part inside the hinge assembly 25, so that the abutment 264 enters the receiving groove 251 along the first sliding groove 265 and the second sliding groove 266. The locking assembly 26 is rotated, and the abutment 264 moves away from the second sliding groove 266, so that the abutment 264 is pressed against the side of the receiving groove 251 near the insertion opening 252 by the rebound force of the compression spring 268.

[0043] Preferably, the side of the abutment 264 away from the hinge assembly 25 is provided with anti-slip texture 267, and the side of the piston rod 262 away from the compression spring 268 is provided with a pressing part.

[0044] It should be noted that the rotation axis of the hinge assembly 25 is fixed to the rotating plate connected to the support block 22, and both ends of the connecting shaft extend into a portion of the rotating plate connected to the guide channel 21.

[0045] Please refer to it again. Figures 3 to 5 Understandably, the specific working principle of this locking component 26 is as follows:

[0046] When the guide channel 21 is fully extended and the hinge assembly 25 falls into the bottom of the guide cover 10, the end of the first rotating plate 253 is directly opposite the locking assembly 26. At this time, the abutment 264 is located at the starting end of the first sliding groove 265. By pressing the pressing part, the piston rod 262 pushes the sleeve 261 into the insertion port 252 and touches the inner wall of the first rotating plate. At this time, the compression spring 268 is compressed, and the piston rod 262 continues to go deeper until the abutment 264 reaches the end of the first sliding groove 265. At this time, the abutment 264 also disengages from the second sliding groove 266 and enters the receiving groove 251. Then, the locking assembly 26 is rotated, and the abutment 264 moves away from the second sliding groove 266. Then the pressing part is released, and the compression spring 268... The rebound force of the spring causes the abutment 264 to press the side of the receiving groove 251 near the insertion port 252 through the rebound force of the compression spring 268, pressing the rotating plate connected to the guide channel 21 against the side wall 101 inside the guide cover 10, thereby restricting the rotation of the hinge assembly 25. It should be noted that when the hinge assembly 25 slides inside the guide cover 10, the first rotating plate 253 slides tightly against the side wall 101 of the guide cover, and the first rotating plate 253 and the second rotating plate 254 can move away from each other along the connecting axis. Therefore, when the locking assembly moves the first rotating plate 252 slightly, the first rotating plate 252 can fit tightly against the side wall of the guide cover 10, thereby restricting the rotation of the first rotating plate 252 and fixing the rotation of the guide channel 21.

[0047] When it is necessary to release the lock on the hinge assembly 25, the reverse action can be performed.

[0048] Furthermore, the pressure relief valve 40 guide mechanism 20 also includes a clamp 30, which is sleeved on the end of the flow guide shroud away from the pressure relief valve 40. Multiple support arms 43 extend from the surface of the clamp 30 toward the end of the pressure relief valve 40, and the free end is trapezoidal. A clamping arm 44 is rotatably connected to the free end of the support arm 43. The clamping arm 44 includes a rotating groove with the same shape as the free end of the support arm 43 and a support foot near the end of the flow guide shroud. The clamp 30 fixes the flow guide shroud to the vent of the pressure relief valve 40. The clamping arm 44 rotates relative to the support arm 43 so that the clamping arm 44 is engaged with the surface of the pressure relief valve 40.

[0049] Specifically, the size of the clip 30 is slightly larger than that of the guide cover 10, and its shape is the same as that of the guide cover 10, both being regular hexagons. On the clip 30, a first clearance groove 41 is provided relative to the lead screw 23, and a second clearance groove 42 is provided relative to the pressing block 263. Except for the side of the clip 30 that has an air vent 16 corresponding to the guide cover 10 and the side that has an adjustment knob 24, the other four sides are provided with the support arm 43.

[0050] The principle by which the clamping arm 44 rotates relative to the supporting arm 43 is as follows:

[0051] Since the shape and size of the rotating groove and the free end of the support arm 43 are the same, both being isosceles trapezoids, when the rotating groove and the support arm 43 are hinged at the short side, the support arm 43 can rotate close to the edge of the rotating groove.

[0052] By adjusting the position of the clamping arm 44, the support feet of the clamping arm 44 are placed on the pressure relief valve 40, and the support feet of the four clamping arms 44 generate a force on each other to fix the clamp 30 and the guide cover 10.

[0053] When using the pressure relief valve guide device provided by the present invention, the guide cover 10 is first initially set at the vent of the pressure relief valve 40, and then the guide cover 10 is firmly fixed by the clamp 30. Finally, according to the position of the pressure relief valve 40 in the engine compartment, the specific orientation of the guide channel 21 is adjusted by the telescopic mechanism and the rotating mechanism to avoid the refrigerant being sprayed onto the high-temperature components in the engine compartment and causing a fire.

[0054] In summary, the pressure relief valve guide device in the above embodiments of the present invention can change the angle and direction of pressure relief without changing the position of the pressure relief valve on the compressor or adjusting the compressor layout, thereby preventing refrigerant from being sprayed onto high-temperature components and causing a fire. It requires minimal modification, low investment, and is easy to platformize.

[0055] The present invention also provides a second embodiment, which, based on the first embodiment, provides an air conditioning compressor that includes the pressure relief valve guide device described in the first embodiment.

[0056] The present invention also provides a third embodiment, which, based on the second embodiment, provides a car that includes the air conditioning compressor described in the second embodiment.
