Description

Technical Field

[0001] This invention relates to the field of climate environment simulation test technology, and in particular to a climate environment simulation test chamber. Background Technology

[0002] Climate environment simulation test chambers can simulate various climatic environmental conditions in nature and are commonly used to conduct environmental adaptability research tests on materials or products. When the test object is an electric motor, the motor is usually placed inside the test chamber, and a dynamometer and other related equipment are connected outside the test chamber to test the motor's performance under different environmental conditions.

[0003] For commercial vehicles, the motors are heavy and bulky, requiring high load-bearing strength from the test chamber. If traditional test chambers are used, the manufacturing cost will increase significantly. In addition, the large size of the motors makes installation difficult due to insufficient space when using traditional test chambers.

[0004] Therefore, there is a need to provide a climate environment simulation test chamber to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a climate environment simulation test chamber that can meet the requirements of high-load testing at the bottom of the chamber without increasing manufacturing costs, and has a large enough operating space to accommodate the installation of the test piece.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A climate environment simulation test chamber includes a test chamber having a containment cavity, the test chamber comprising:

[0008] The bottom of the box is fixedly set on the mounting plane, and several bearing members pass through the bottom of the box. One end of each bearing member is set on the mounting plane, and the test piece is installed on the other end of the several bearing members.

[0009] A box body is disposed on one side of the bottom of the box. The box body includes a first opening and a second opening. The box body is movable toward the bottom of the box so that the bottom of the box blocks the first opening.

[0010] A door is located on the other side of the bottom of the box. The door can move toward the bottom of the box to abut against the side wall of the box and block the second opening.

[0011] A fastening assembly is provided to secure the door to the housing, the bottom of the housing, the housing, and the door are arranged to form the test chamber, and the test piece is located within the accommodating cavity.

[0012] Preferably, the bottom of the box includes a bottom plate and a plurality of first support seats disposed at the lower end of the bottom plate. The first support seats are used to support the bottom plate, and the height of the first support seats is adjustable.

[0013] Preferably, the base plate has a first cavity inside, and the first cavity is filled with thermal insulation material.

[0014] Preferably, the base plate has a plurality of through holes, the bearing member passes through the through holes, and the hole wall of the through holes is covered with a first heat insulation member.

[0015] Preferably, the door includes a door panel and a plurality of second support seats disposed at the lower end of the door panel. The second support seats are used to support the door panel, and the height of the second support seats is adjustable.

[0016] Preferably, the door panel has a shaft hole, and the shaft of the part to be tested is connected to the dynamometer through the shaft hole.

[0017] Preferably, the door panel includes a door panel body and a mounting plate, the mounting plate being detachably mounted on the door panel body, and the shaft hole being formed on the mounting plate.

[0018] Preferably, the first opening of the box is a trapezoidal opening, the bottom of the box has a trapezoidal cross-section, and the box can be locked inside the first opening to seal the first opening.

[0019] Preferably, the fastening assembly includes a latch and a buckle, with one of the door and the body of the box having the latch and the other having the buckle, and the latch and buckle being fastened together.

[0020] Preferably, the climate environment simulation test chamber further includes a drive component, which includes:

[0021] A base, the housing is mounted on the base, and a gear is rotatably mounted on the bottom of the base;

[0022] A rack plate, the gear meshing with the rack plate;

[0023] A drive unit capable of driving the gear to rotate, causing the base to move in a direction closer to or away from the bottom of the box.

[0024] The beneficial effects of this invention are:

[0025] This climate environment simulation test chamber includes a test chamber with a accommodating cavity. The test chamber includes a bottom, a body, and a door. The bottom is fixedly mounted on a mounting plane, and several support members pass through the bottom. One end of each support member is positioned on the mounting plane, and the test piece is mounted on the other end of each support member. The body is located on one side of the bottom and includes a first opening and a second opening. The body can move towards the bottom to block the first opening. The door is located on the other side of the bottom and can move towards the bottom to abut against the side wall of the body and block the second opening. Fastening components secure the door to the body. The bottom, body, and door form the test chamber, and the test piece is located within the accommodating cavity.

[0026] The test chamber contains a housing cavity for the test piece (DPT), which simulates the required temperature and humidity conditions for testing the DPT. Several support members extending through the bottom of the chamber, with one end of each member positioned on a mounting plane, collectively support the DPT, allowing it to be placed within the housing cavity for subsequent testing. This eliminates the need for the bottom of the chamber to bear the weight of the DPT, thus avoiding additional manufacturing costs to meet high-load testing requirements. In this invention, four support members are arranged in a square to support the DPT. By configuring the test chamber with independent bottom, door, and body, the door and body can be moved away from the bottom during DPT installation, providing sufficient operating space. The door and body are secured with fastening components, with the bottom sandwiched between them, forming the test chamber for testing the DPT installed within the housing cavity. Before testing, install the test piece onto the carrier, then move the door to the bottom of the box, and then move the box body to the bottom of the box. Use fastening components to secure the door and the box body together before proceeding with the subsequent tests. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0039] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0042] Climate environment simulation test chambers can simulate various climatic conditions in nature and are commonly used to conduct environmental adaptability studies on materials or products. When the test object is an electric motor, the motor is usually placed inside the test chamber, and a dynamometer and other related equipment are connected to the outside of the chamber to test the motor's performance under different environmental conditions. For commercial vehicles, the motors are heavy and large, requiring high load-bearing capacity from the test chamber. Using traditional test chambers would significantly increase manufacturing costs, and the large size of the motors would make installation difficult due to insufficient space when using traditional test chambers.

[0043] To solve the above problems, such as Figures 1-4 As shown, this embodiment provides a climate environment simulation test chamber, which includes a test chamber 1 with a receiving cavity. The test chamber 1 includes a bottom 11, a body 12, and a door 13. The bottom 11 is fixedly mounted on an installation plane, and several support members pass through the bottom 11. One end of each support member is mounted on the installation plane, and the test piece is mounted on the other end of the support member. The body 12 is located on one side of the bottom 11 and includes a first opening 121 and a second opening 122. The body 12 can move toward the bottom 11 to block the first opening 121. The door 13 is located on the other side of the bottom 11 and can move toward the bottom 11 to abut against the side wall of the body 12 and block the second opening 122. A fastening assembly 14 can fix the door 13 to the body 12. The bottom 11, body 12, and door 13 surround the test chamber 1, and the test piece is located within the receiving cavity.

[0044] The test chamber 1 contains the test piece (DPT), and the test chamber 1 can simulate the temperature and humidity conditions required for testing the DPT. By installing several support members that pass through the bottom 11 of the chamber, with one end of each support member positioned on the mounting plane, the support members collectively support the DPT, allowing it to be positioned within the chamber for subsequent testing. This eliminates the need for the bottom 11 to bear the weight of the DPT, thus avoiding additional manufacturing costs to meet the requirements of high-weight load testing. In this embodiment, four support members are arranged in a square to support the DPT. By configuring the test chamber 1 with independent bottom 11, door 13, and body 12, when installing the DPT, the door 13 and body 12 can be moved away from the bottom 11, providing sufficient operating space for DPT installation. The door 13 and the housing 12 are secured by the fastening assembly 14, with the bottom 11 sandwiched between them, thus forming the test chamber 1 for testing the component under test (DUT) installed within the accommodating cavity. Before testing, the DUT is first installed onto the support, then the door 13 is moved until it abuts against the bottom 11, and then the housing 12 is moved until it abuts against the bottom 11. The fastening assembly 14 is then used to securely connect the door 13 and the housing 12, allowing subsequent testing to proceed. It should be noted that the DUT in this embodiment is a motor; however, it could also be other materials or components to be tested.

[0045] In this embodiment, sealing strips are provided at the joints between the bottom 11, the door 13, and the body 12. These sealing strips effectively isolate external environmental interference within the test chamber 1, ensuring the accuracy and stability of environmental parameters within the test chamber 1, and thus guaranteeing the reliability and stability of the test results. The sealing strips can be made of silicone.

[0046] Specifically, such as Figure 2 As shown, the bottom of the chamber 11 includes a base plate 111 and a plurality of first support seats 112 disposed at the lower end of the base plate 111. The first support seats 112 are used to support the base plate 111, and the height of the first support seats 112 is adjustable. The first support seats 112 are used to support the base plate 111, and by adjusting the height of the first support seats 112, it can be ensured that an appropriate gap is maintained between the base plate 111 and the ground; and by adjusting the height of the first support seats 112, the height of the base plate 111 can be adjusted so that it can precisely seal the first opening 121, ensuring good airtightness of the assembled test chamber 1.

[0047] In this embodiment, the base plate 111 has a first cavity inside, which is filled with thermal insulation material. The thermal insulation material filled in the first cavity effectively blocks the heat transfer path between the air inside the test chamber 1 and the external ambient air, ensuring that the temperature conditions inside the test chamber 1 are not affected by the outside environment, and ensuring the accuracy and reliability of the test results.

[0048] Specifically, the base plate 111 includes a first plate and a second plate disposed opposite to each other, with several side plates disposed between the first plate and the second plate. The first plate, the second plate, and the side plates together form the base plate 111 having a first cavity. The first plate and the second plate are made of metal, such as stainless steel or aluminum alloy, while the side plates are made of FR4 epoxy resin. The first plate and the second plate are made of metal, which has good thermal conductivity and corrosion resistance, enabling rapid dissipation of heat generated within the test chamber 1 and resistance to corrosive environments. The FR4 epoxy resin plate has high strength, good rigidity, and good insulation properties, and is not easily conductive, thus isolating the test chamber 1 from the outside temperature at the base plate 111, ensuring the temperature stability within the test chamber 1.

[0049] Specifically, such as Figure 1 As shown, the base plate 111 has several through holes 1111 through which the support member passes. The walls of the through holes 1111 are covered with a first heat insulation member (not shown in the figure). The presence of the first heat insulation member effectively blocks the direct heat transfer path between the inside and outside of the base plate 111. This helps maintain the temperature stability inside the test chamber 1 and prevents the heat or cold transferred by the ambient air through the through holes 1111 from adversely affecting the test environment. It is worth mentioning that the number of through holes 1111 depends on the number of support members required. This embodiment does not limit this; for example, the number of through holes 1111 is four.

[0050] In this embodiment, the first heat insulation component is made of epoxy resin. In other embodiments, the first heat insulation component is made of polyurethane or polypropylene. It should be noted that the specific material of the first heat insulation component is selected according to actual needs, and this embodiment does not limit it.

[0051] Furthermore, silicone is used to seal the via 1111 a second time around the support to prevent the via 1111 from having tiny gaps between the hole wall and the support, which would cause the external ambient air to transfer heat or cold through the tiny gaps and adversely affect the test environment.

[0052] For details, please refer to [link / reference]. Figure 2 The base plate 111 is also provided with a drainage hole 1112. Due to temperature differences or humidity changes, condensation may occur in the test chamber 1. If this condensation cannot be drained in time, it will accumulate in the test chamber 1, causing the ambient humidity to rise, which will adversely affect the accuracy and stability of the test results. The drainage hole 1112 can effectively drain this condensation, maintain a dry environment in the test chamber 1, and ensure the accuracy and reliability of the test.

[0053] Specifically, such as Figure 2As shown, the door 13 includes a door panel 131 and several second support seats 132 disposed at the lower end of the door panel 131. The second support seats 132 are used to support the door panel 131, and the height of the second support seats 132 is adjustable. By adjusting the height of the second support seats 132, it is possible to ensure that an appropriate gap is maintained between the door panel 131 and the ground; and by adjusting the height of the second support seats 132, the height of the door panel 131 can be adjusted so that it can just abut against the bottom 11 of the chamber and seal the second opening 122, ensuring good airtightness of the assembled test chamber 1.

[0054] In this embodiment, the door panel 131 has a second cavity inside, which is filled with thermal insulation material. The thermal insulation material in the second cavity effectively blocks the heat transfer path between the air inside the test chamber 1 and the external ambient air, ensuring that the temperature conditions inside the test chamber 1 are not affected by the outside environment, and ensuring the accuracy and reliability of the test results.

[0055] Furthermore, the door panel 131 is made of metal, such as stainless steel or aluminum alloy. Metal materials have good thermal conductivity and corrosion resistance, which can quickly dissipate the heat generated in the test chamber 1 and resist the erosion of the corrosive environment.

[0056] Specifically, such as Figure 2 As shown, a shaft hole 133 is provided on the door panel 131, and the shaft of the part to be tested is connected to the dynamometer through the shaft hole 133. The dynamometer is used to test the part to be tested.

[0057] In this embodiment, please continue to refer to Figure 2 The door panel 131 includes a door panel body 1311 and a mounting plate 1312. The mounting plate 1312 is detachably mounted on the door panel body 1311, and a shaft hole 133 is formed in the mounting plate 1312. By setting the shaft hole 133 in the mounting plate 1312, and making the mounting plate 1312 detachably connected to the door panel body 1311, it is convenient to adjust or repair the connection between the shaft of the test piece or the dynamometer during the testing process. Specifically, the mounting plate 1312 is fixed to the door panel body 1311 using bolts. Bolts are simple to obtain and inexpensive, and the mounting plate 1312 can be easily fixed or removed from the door panel body 1311 by tightening the bolts.

[0058] Specifically, such as Figure 2As shown, the door panel 131 also has several wire holes 134. Power cables, transmission lines, etc., that need to be connected to the device under test (DUT) extend from the outside into the test chamber 1 through the wire holes 134 to connect to the DUT. In this embodiment, the walls of the wire holes 134 are covered with a second heat insulation element (not shown in the figure). The presence of the second heat insulation element effectively blocks the direct heat transfer path between the inside and outside of the door panel 131. This helps maintain the temperature stability inside the test chamber 1 and prevents the heat or cold transferred from the external ambient air through the wire holes 134 from adversely affecting the test environment. It is worth mentioning that the number of wire holes 134 depends on the required number of power cables, transmission lines, etc., and this embodiment does not limit this.

[0059] In this embodiment, the second heat insulation component is made of epoxy resin. In other embodiments, the second heat insulation component is made of polyurethane or polypropylene. It should be noted that the specific material of the second heat insulation component is selected according to actual needs, and this embodiment does not limit it.

[0060] Specifically, such as Figure 2 As shown, the door 13 also includes several lifting rings 135, which are disposed at the top of the door panel 131. The lifting rings 135 allow the door 13 to be easily lifted and moved by directly connecting ropes, chains, or lifting equipment when it needs to be moved, so that the door 13 can be moved closer to or away from the bottom 11. This method of movement is more efficient and labor-saving than traditional manual handling, significantly reducing labor costs and avoiding potential injuries during handling.

[0061] In this embodiment, please continue to refer to Figure 2 The door 13 also includes a shelf 136, which is located on the side of the door panel 131 facing the bottom 11 of the box. The shelf 136 can conveniently place items such as power cords and transmission cables, and prevent them from falling onto the bottom 11 of the box.

[0062] Specifically, such as Figure 2 , Figure 3 As shown, the first opening 121 of the chamber 12 is trapezoidal, and the bottom 11 of the chamber has a trapezoidal cross-section. The bottom 11 can be locked inside the first opening 121 to seal it. The trapezoidal design allows the bottom 11 to be more tightly locked inside the first opening 121 when the chamber 12 moves towards the bottom 11, thereby effectively reducing or avoiding gaps and enhancing the airtightness of the test chamber 1. This ensures that the environmental parameters inside the test chamber 1 remain stable and unaffected by external interference when simulating various climatic environments, thus improving the accuracy and reliability of the test.

[0063] In this embodiment, the chamber 12 has a third cavity filled with thermal insulation material. The thermal insulation material in the third cavity effectively blocks the heat transfer path between the air inside the test chamber 1 and the ambient air outside, ensuring that the temperature conditions inside the test chamber 1 are not affected by the outside environment, and ensuring the accuracy and reliability of the test results.

[0064] Furthermore, the enclosure 12 is made of metal, such as stainless steel or aluminum alloy. Metal materials have good thermal conductivity and corrosion resistance, which can quickly dissipate the heat generated in the test chamber 1 and resist the erosion of the corrosive environment.

[0065] In this embodiment, as Figure 1 , Figure 3 As shown, the housing 12 is provided with an observation window 123 so that the operator can observe the test piece being tested in the test chamber 1.

[0066] Specifically, such as Figure 1 , Figure 4 As shown, the fastening assembly 14 includes a latch 141 and a buckle 142. One of the door 13 and the housing 12 is provided with a latch 141, and the other with a buckle 142. The latch 141 and buckle 142 are fastened together. The design of the latch 141 and buckle 142 allows the door 13 to be quickly connected or separated from the housing 12, improving operational convenience and reducing the time and labor costs required for installation and disassembly. The tight fastening of the latch 141 and buckle 142 ensures a good seal between the door 13 and the housing 12, thereby guaranteeing the accuracy and reliability of the test.

[0067] It should be noted that the interlocking of the clasp 141 and the buckle 142 to achieve a tight connection is a common method in the prior art. The specific structure and working principle of the two will not be described in detail in this embodiment.

[0068] In some embodiments, the latch 141 is disposed on the door 13 and the buckle 142 is disposed on the body 12; in other embodiments, the latch 141 is disposed on the body 12 and the buckle 142 is disposed on the door 13. The specific arrangement depends on the actual needs, and this embodiment does not limit it. It should be noted that there are multiple fastening components 14, and multiple fastening components 14 together lock the door 13 and the body 12.

[0069] Specifically, such as Figure 3As shown, the test chamber 1 has a partition 124 inside to divide it into a test chamber and an air conditioning chamber. The test piece is located in the test chamber, and the air conditioning chamber and the test chamber are connected by an air outlet and an air inlet. The air conditioning chamber contains an evaporator, a heater, a humidifying pipe, a fan, etc. The fan delivers air from the air conditioning chamber, which meets certain temperature and humidity conditions, to the test chamber, thereby simulating the required temperature and humidity natural environment conditions within the test chamber. The test piece undergoes relevant tests under these simulated environmental conditions.

[0070] Specifically, such as Figure 1 As shown, this climate environment simulation test chamber also includes a unit compartment 3, which is used to provide cooling energy to the evaporator in the air conditioning cavity. Specifically, the unit compartment 3 also includes a refrigeration system composed of a compressor, condenser, valves, and several pipes, which further facilitates the provision of cooling energy to the evaporator in the air conditioning cavity.

[0071] Furthermore, for some test conditions that require a certain level of humidity, the unit room 3 in this embodiment also includes a humidification mechanism to generate humidity, which supplies moisture to the air-conditioning cavity through a humidification pipe, such as a steam humidifier.

[0072] Specifically, such as Figure 1 As shown, this climate environment simulation test chamber also includes a control room 2. The control room 2 provides both high-voltage and low-voltage control for the climate environment simulation test chamber, controlling its power supply, signal reception, transmission, and processing to maintain its normal operation. Specifically, in this embodiment, the control room 2 includes a controller and control components, such as circuit breakers, contactors, relays, and PLCs. The controller controls the circuit switching of the compressor, heater, various valves, humidification mechanism, fan, alarm, etc.

[0073] Specifically, such as Figure 1 As shown, this climate environment simulation test chamber also includes a drive assembly, which includes a base 41, a rack plate 42, and a drive component (not shown in the figure). The chamber body 12 is mounted on the base 41, and a gear is rotatably mounted on the bottom of the base 41. The gear meshes with the rack plate 42, and the drive component can drive the gear to rotate, so that the base 41 moves towards or away from the bottom of the chamber 11. By driving the gear to rotate through the drive component, the gear can move along the extension direction of the rack plate 42, thereby moving towards or away from the bottom of the chamber 11. The drive method is simple, and moving the bottom of the chamber 11 is convenient and quick. Specifically, the rack plate 42 is fixedly mounted on the mounting plane.

[0074] In this embodiment, the driving component is a torque motor. In other embodiments, the driving component may also be a cylinder. It should be noted that any structure in the prior art capable of driving gear rotation can be used as the driving component in this embodiment, and this embodiment does not limit it.

[0075] Furthermore, such as Figure 1 As shown, this climate environment simulation test chamber also includes a guide assembly 5, which includes a guide rail 51 and a guide block 52. The guide rail 51 and the guide block 52 are slidably connected. One of the base 41 and the mounting plane is provided with a guide rail 51, and the other is provided with a guide block 52. The guide assembly 5 provides stable guidance for the movement of the base 41, ensuring that the base 41 can move smoothly along a predetermined trajectory during movement, avoiding deviation or shaking.

[0076] In some embodiments, the guide rail 51 is disposed on the mounting plane, and the guide block 52 is disposed on the base 41; in other embodiments, the guide rail 51 is disposed on the base 41, and the guide block 52 is disposed on the mounting plane. It should be noted that the specific arrangement of the guide rail 51 and the guide block 52 depends on actual needs, and this embodiment does not limit this.

[0077] In this embodiment, as Figure 1 As shown, there are two guide components 5, which are located on both sides of the rack plate 42. The presence of guide components 5 on both sides provides more stable support and guidance for the movement of the base 41, helps prevent the base 41 from tilting or twisting during movement, and ensures that the base 41 always moves along the predetermined trajectory.

[0078] In this embodiment, please continue to refer to Figure 1 The guide rail 51 is set on the mounting plane. Limit switches 6 are set at both ends of the guide rail 51. When the base 41 moves to contact the limit switch 6, the limit switch 6 transmits a signal to the drive to stop working, thereby stopping the box 12 from moving, so as to ensure that the box 12 will not hit the bottom 11 or move out of the guide rail 51.

[0079] Specifically, both the control room 2 and the unit room 3 are located on the base 41, and the control room 2, the unit room 3 and the enclosure 12 are combined into a whole, which can move close to or away from the bottom of the enclosure 11.

[0080] The following is a detailed explanation of how to use this climate simulation test chamber:

[0081] Install the test piece onto the support, and use ropes, chains, or hoisting equipment to connect the lifting ring 135 to lift and move the chamber door 13 so that it approaches and abuts against the bottom 11. Then connect the shaft of the test piece to the dynamometer. After the connection is completed, drive the gear to rotate so that the chamber 12, control room 2, and unit room 3 move together toward the bottom 11. When the base 41 contacts the limit switch 6, the chamber 12 has abutted against the bottom 11. Then fasten the buckle 142 and the ring 141. Start the climate simulation test chamber and dynamometer to test the test piece. After the test, loosen the latch 141 and buckle 142 to allow the drive gear to rotate, causing the housing 12, control room 2, and unit room 3 to move away from the bottom 11. The test will stop automatically when the base 41 contacts another limit switch 6. Disconnect the shaft of the test piece from the dynamometer, and then use ropes, chains, or hoisting equipment to connect the lifting ring 135 to lift and move the door 13 away from the bottom 11. Finally, remove the test piece.
