Description
Technical Field
[0001] This utility model relates to the field of air conditioning performance testing technology, and in particular to a test bench. Background Technology
[0002] The air conditioning defrosting function is an important component of the car's air conditioning system. It is mainly used to remove or prevent fog or frost on the vehicle's windshield to ensure clear visibility for the driver and improve driving safety. It is usually connected to the air conditioning unit inside the car through ventilation pipes to deliver air to the windshield and side windows, thereby defogging and defrosting the vehicle.
[0003] Air conditioning defrosting and defogging performance testing is an important evaluation task, mainly to ensure that the performance of the automotive air conditioning system in dehumidification, defrosting and defogging can meet the design requirements and actual use needs.
[0004] When conducting air conditioning defrosting and defogging performance tests, the placement of the air conditioning unit and ventilation ducts must be completely consistent with their position and condition during vehicle assembly. Currently, existing test benches cannot test air conditioning units for multiple vehicle models, which requires the creation of a matching test bench for each type of vehicle's air conditioning unit, resulting in excessively high testing costs.
[0005] Therefore, it is necessary to provide a new test bench to solve the above-mentioned technical problems. Utility Model Content
[0006] The main purpose of this invention is to propose a test bench that aims to improve the technical problem of excessively high costs in testing the defogging and defrosting performance of air conditioners in the prior art.
[0007] To achieve the above objectives, this utility model proposes a test bench, comprising:
[0008] A base, on which two first sliding grooves are formed;
[0009] A suspension assembly includes a crossbeam, two connecting arms, and two vertical plates. The two vertical plates are slidably installed in two first sliding grooves, and the two vertical plates are spaced apart. The two connecting arms are respectively installed on the two vertical plates. The two ends of the crossbeam are respectively connected to the two connecting arms. The crossbeam is used to suspend the air conditioning unit.
[0010] A support assembly includes a support plate and a support component. The support plate is mounted on the base and has a second sliding groove formed thereon. The support component is slidably mounted in the second sliding groove and is used to support the air conditioner.
[0011] In one embodiment, a plurality of mounting positions are formed on the vertical plate, the plurality of mounting positions are spaced apart along the vertical direction, and the mounting positions include a plurality of positioning holes spaced apart along a first direction. The connecting arm is detachably mounted to the base through the positioning holes, and the vertical direction is perpendicular to the first direction.
[0012] In one embodiment, the connecting arm has a mounting hole, and the suspension assembly further includes a locking member that passes through the positioning hole and is mounted in the mounting hole.
[0013] In one embodiment, both the first groove and the second groove extend along a second direction, which is perpendicular to the vertical direction and also perpendicular to the first direction.
[0014] In one embodiment, a positioning post is formed on the base, and a fixing hole is also formed on the support plate. The positioning post is installed in the fixing hole. There are multiple positioning posts and multiple fixing holes. The multiple positioning posts are distributed in a rectangular shape. The number of multiple positioning posts is equal to the number of multiple fixing holes, and they are set in a one-to-one correspondence.
[0015] In one embodiment, the support component includes a lifting platform and a support sub-component. The support sub-component is installed on the top of the lifting platform, and the bottom of the lifting platform is slidably installed in the second slide groove. The lifting platform can be raised or lowered in the vertical direction.
[0016] In one embodiment, the support component further includes a locking screw, and a through hole is formed at the bottom of the lifting platform. The locking screw is telescopically installed in the through hole and can extend out of the through hole to abut against the bottom of the second slide groove.
[0017] In one embodiment, the support sub-component includes a base, a first support arm, a second support arm, and a support member. The bottom of the base is mounted on the lifting platform, and the first support arm, the second support arm, and the support member are all mounted on the top of the base. The first support arm, the second support arm, and the support member are all used to engage with the air conditioner.
[0018] In one embodiment, the first support arm, the second support arm, and the support member are arranged in a triangular structure.
[0019] In one embodiment, there are multiple support members, and each of the multiple support members can be detachably installed on the top of the base.
[0020] In the above scheme, the test bench includes a base, a suspension assembly, and a support assembly. The base has two first sliding grooves. The suspension assembly includes a crossbeam, two connecting arms, and two vertical plates. The two vertical plates are slidably installed in the two first sliding grooves and are spaced apart. The two connecting arms are installed in the two vertical plates. The two ends of the crossbeam are connected to the two connecting arms respectively. The crossbeam is used to suspend the air conditioning unit. The support assembly includes a support plate and a support component. The support plate is installed on the base. A second sliding groove is formed on the support plate. The support component is slidably installed in the second sliding groove. The support component is used to support the air conditioner. When conducting air conditioning defrosting and defogging performance tests, it's necessary to first determine the position of the air conditioning unit relative to the windshield and two side windows within the actual vehicle. The air conditioning unit is installed in a model corresponding to its type. Then, operators measure the positional relationship between the air conditioning unit and the windshield and side windows. Based on the measured position information, and since different air conditioning units will be connected to a crossbeam during testing, the position information of the two ends of the crossbeam can be calculated. Operators then control the two vertical plates in the two second sliding grooves, adjusting the position between the two connecting arms on the two vertical plates. The two ends of the crossbeam are connected to the two connecting arms, ensuring that the current position information of the two ends of the crossbeam matches the measured position information. At this point, the air conditioning unit is suspended on the crossbeam; this position is the actual position of the air conditioning unit in the actual vehicle. According to the current position of the air conditioning unit, the drive support component slides in the second slide groove, causing the support component to move to the bottom of the air conditioning unit and abut against the bottom of the air conditioning unit to support it. After setting, the ventilation pipe is installed on the air conditioning unit, and the air conditioning defogging and defrosting performance test is performed. In this utility model, by sliding the vertical plate in the first slide groove, the positional relationship between the two connecting arms and the positional information of the crossbeam can be adjusted, so that the position of the air conditioning unit of different types of vehicles suspended on the test bench corresponds to the position of the air conditioning unit in the vehicle. This ensures the accuracy of the air conditioning defogging and defrosting performance test. Compared with the prior art, which requires a separate test bench for the defogging and defrosting performance test of the air conditioning unit of each type of vehicle, this utility model only requires one test bench to meet the defogging and defrosting performance test of the air conditioning unit of various types of vehicles, thus greatly reducing the cost of defogging and defrosting performance testing.

[0032] When conducting air conditioning defrosting and defogging performance tests, the placement of the air conditioning unit and ventilation ducts must be completely consistent with their position and condition during vehicle assembly. Currently, existing test benches cannot test air conditioning units for multiple vehicle models, which requires the creation of a matching test bench for each type of vehicle's air conditioning unit, resulting in excessively high testing costs.
[0033] Figure 1 In the diagram, X represents the first direction, Y represents the second direction, and Z represents the vertical direction.
[0034] Please see Figures 1 to 3This utility model proposes a test bench 100, including a base 1, a suspension assembly 2, and a support assembly 3. The base 1 has two first sliding grooves 11. The suspension assembly 2 includes a crossbeam 21, two connecting arms 22, and two vertical plates 23. The two vertical plates 23 are slidably installed in the two first sliding grooves 11, and the two vertical plates 23 are spaced apart. The two connecting arms 22 are respectively installed in the two vertical plates 23. The two ends of the crossbeam 21 are respectively connected to the two connecting arms 22. The crossbeam 21 is used to suspend the air conditioning unit. The support assembly 3 includes a support plate 31 and a support component 32. The support plate 31 is installed in the base 1, and a second sliding groove 311 is formed on the support plate 31. The support component 32 is slidably installed in the second sliding groove 311. The support component 32 is used to support the air conditioner. When conducting air conditioning defrosting and defogging performance tests, it is necessary to first determine the position of the air conditioning unit relative to the windshield and two side windows in the actual vehicle. The air conditioning unit is installed in a model of the corresponding vehicle type. Then, the operator measures the positional relationship between the air conditioning unit and the windshield and two side windows. Based on the measured positional information of the air conditioning unit, and since different air conditioning units will be connected to the crossbeam 21 during testing, the operator can calculate the positional information of both ends of the crossbeam 21. The operator then controls the two vertical plates 23 to slide in the two first sliding grooves 11, adjusting the position between the two connecting arms 22 on the two vertical plates 23. The two ends of the crossbeam 21 are connected to the two connecting arms 22 respectively, so that the current positional information of the two ends of the crossbeam 21 is the same as the measured positional information of the two ends of the crossbeam 21. At this point, the air conditioning unit is suspended on the crossbeam 21; the position of the air conditioning unit at this time is the position of the air conditioning unit in the actual vehicle. According to the current position of the air conditioning unit, the drive support component 32 slides in the second slide groove 311, so that the support component 32 moves to the bottom of the air conditioning unit and abuts against the bottom of the air conditioning unit to support the air conditioning unit; after the setting is completed, the ventilation pipe is installed on the air conditioning unit, and the air conditioning defogging and defrosting performance test is carried out; in this utility model, by sliding the vertical plate 23 in the first slide groove 11, the positional relationship between the two connecting arms 22 and the position information of the crossbeam 21 can be adjusted, so that the position of the air conditioning unit of different types of vehicles suspended on the test bench 100 corresponds to the position of the air conditioning unit in the vehicle, thus ensuring the accuracy of the air conditioning defogging and defrosting performance test; compared with the prior art, which requires an independent test bench 100 for the defogging and defrosting performance test of the air conditioning unit of each type of vehicle, this embodiment only needs one test bench 100 to meet the defogging and defrosting performance test of the air conditioning unit of various types of vehicles, thus greatly reducing the cost of defogging and defrosting performance test.
[0035] Please see Figure 1 and Figure 2In one embodiment, a plurality of mounting positions 231 are formed on the vertical plate 23. The plurality of mounting positions 231 are spaced apart along the vertical direction. The mounting positions 231 include a plurality of positioning holes 231a spaced apart along the first direction. The connecting arm 22 is detachably mounted to the base 1 through the positioning holes 231a. The vertical direction is perpendicular to the first direction. Specifically, the operator controls the two vertical plates 23 to slide in the two first slide grooves 11 respectively, then disassembles the connecting arm 22 from the second positioning hole 231a, moves the connecting arm 22 to the previously measured position, and then connects the connecting arm 22 to the corresponding positioning hole 231a. This ensures that the position between the two connecting arms 22 matches the previously measured position information of the two ends of the crossbeam 21. At this time, the air conditioning unit is suspended on the crossbeam 21, and the position of the air conditioning unit at this time is the position of the air conditioning unit in the actual vehicle. Then, according to the current position of the air conditioning unit, the support component 32 is driven to slide in the second slide groove 311, so that the support component 32 moves to the bottom of the air conditioning unit and abuts against the bottom of the air conditioning unit to support the air conditioning unit. After the setup is completed, the ventilation pipe is installed on the air conditioning unit, and the air conditioning defrosting performance is tested. The above setup makes the movement distance of the connecting arm 22 more accurate, ensuring that the position of the air conditioning unit when suspended on the test bench 100 corresponds accurately to the position of the air conditioning unit in the actual vehicle.
[0036] Please see Figure 1 and Figure 3 In one embodiment, the connecting arm 22 has a mounting hole 221, and the suspension assembly 2 further includes a locking member 24, which is installed in the mounting hole 221 through a positioning hole 231a. The connecting arm 22 is connected to the vertical plate 23 by the locking member 24. This structure can increase the connection strength between the vertical plate 23 and the connecting arm 22, and can achieve quick disassembly and installation.
[0037] Please see Figures 1 to 3In one embodiment, both the first slide groove 11 and the second slide groove 311 extend along a second direction, which is perpendicular to the vertical direction and also perpendicular to the first direction. The operator controls the two vertical plates 23 to slide in the two first slide grooves 11, which extend along the second direction. Then, the connecting arm 22 is disassembled from the second positioning hole 231a and moved to the previously measured position, i.e., moved along the first direction and the vertical direction. Then, the connecting arm 22 is connected to the corresponding positioning hole 231a. This ensures that the position between the two connecting arms 22 matches the previously measured position information of the two ends of the crossbeam 21. At this point, the air conditioning unit is suspended on the crossbeam 21, and its current position is the position of the air conditioning unit in the actual vehicle. Then, according to the current position of the air conditioning unit, the drive support component 32 slides in the second slide groove 311, so that the support component 32 moves to the bottom of the air conditioning unit and abuts against the bottom of the air conditioning unit to support the air conditioning unit; after the setting is completed, the ventilation pipe is installed on the air conditioning unit, and the air conditioning defogging and defrosting performance test is carried out; since the second direction is perpendicular to the vertical direction, and the second direction is perpendicular to the first direction, and the vertical direction is perpendicular to the first direction, the position adjustment in three directions is realized, which greatly increases the types of air conditioning units that the test bench 100 can be used for, and greatly increases the applicability range of the test bench 100.
[0038] Please see Figure 1 and Figure 3 In one embodiment, a positioning post 12 is formed on the base 1, and a fixing hole 312 is formed on the support plate 31. The positioning post 12 is installed in the fixing hole 312. There are multiple positioning posts 12 and multiple fixing holes 312. The multiple positioning posts 12 are distributed in a rectangular shape, and the number of multiple positioning posts 12 is equal to the number of multiple fixing holes 312, and they are arranged in a one-to-one correspondence. By setting the fixing hole 312 on the support plate 31 and machining the positioning post 12 on the base 1, the fixing hole 312 of the support plate 31 is aligned with the positioning post 12, and the positioning post 12 is inserted into the fixing hole 312. This allows the support plate 31 to be fixedly connected to the base 1, and this connection structure facilitates the installation and disassembly of the support plate 31. Setting multiple positioning posts 12 and distributing them in a rectangular shape allows all positions of the support plate 31 to be fixedly connected to the base 1.
[0039] Please see Figure 1 and Figure 3In one embodiment, the support component 32 includes a lifting platform 321 and a support sub-component 322. The support sub-component 322 is mounted on the top of the lifting platform 321, and the bottom of the lifting platform 321 is slidably mounted on the second slide groove 311. The lifting platform 321 can be raised or lowered vertically. When the air conditioner is suspended on the crossbeam 21, the operator drives the lifting platform 321 to slide in the second slide groove 311, moving the lifting platform 321 to the bottom of the air conditioner. Then, the lifting platform 321 rises upward until the support sub-component 322 abuts against the bottom of the air conditioner, and then testing is performed. This prevents the air conditioner from falling during the testing process.
[0040] Please see Figure 1 and Figure 3 In one embodiment, the support component 32 further includes a locking screw 323. A through hole 321a is formed at the bottom of the lifting platform 321. The locking screw 323 is telescopically installed in the through hole 321a and can extend out of the through hole 321a to abut against the bottom of the second slide groove 311. When the air conditioner is suspended on the crossbeam 21, the locking screw 323 extends out of the through hole 321a into the second slide groove 311. The operator drives the locking screw 323 to slide in the second slide groove 311, causing the lifting platform 321 to move along the extension direction of the second slide groove 311. When the lifting platform 321 moves to the bottom of the air conditioner, the operator extends the locking screw 323 to abut against the bottom of the second slide groove 311, thus preventing the lifting platform 321 from moving further. Then, the lifting platform 321 rises upwards until the support sub-component 322 abuts against the bottom of the air conditioner, and then testing is performed. This structural design prevents the lifting platform 321 from moving during testing.
[0041] Please see Figure 1 and Figure 4 In one embodiment, the support sub-component 322 includes a base 322a, a first support arm 322b, a second support arm 322c, and a support member 322d. The bottom of the base 322a is mounted on the lifting platform 321. The first support arm 322b, the second support arm 322c, and the support member 322d are all mounted on the top of the base 322a. The first support arm 322b, the second support arm 322c, and the support member 322d are all used to engage with the air conditioner. When the lifting platform 321 moves to the bottom of the air conditioner, the operator engages the first support arm 322b, the second support arm 322c, and the support member 322d with the engaging slots at the bottom of the air conditioner, thus further preventing the air conditioner from falling.
[0042] Please see Figure 1 and Figure 4In one embodiment, the first support arm 322b, the second support arm 322c, and the support member 322d are arranged in a triangular structure. By arranging the first support arm 322b, the second support arm 322c, and the support member 322d in a triangular structure, the high stability of the triangular structure ensures that the air conditioner is more stable after all three arms are engaged with it.
[0043] In one embodiment, there are multiple support members 322d, and all support members 322d are detachably installed on the top of the base 322a. By providing multiple detachable support members 322d, depending on the type of air conditioner, the support members 322d can be disassembled and installed at corresponding positions on the base 322a, so that the support members 322d can match the snap-fit grooves at the bottom of the air conditioner.
[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
