Description

Technical Field

[0001] This utility model relates to the technical field of vehicle brake fluid testing devices, and in particular to a vehicle brake fluid evaporation performance testing device. Background Technology

[0002] Vehicle brake fluid may evaporate during use due to high temperatures or prolonged exposure, affecting braking performance. Existing testing methods mostly rely on manual inspection or simple temperature tests, which have low accuracy and efficiency. Therefore, an efficient and accurate brake fluid evaporation performance testing device that can monitor brake fluid evaporation in real time and ensure the safety and reliability of the vehicle braking system has significant application value.

[0003] However, in practical use, the following shortcomings still exist. For example, existing vehicle brake fluid evaporation performance testing devices cannot simulate the state of brake fluid in the automotive operating environment when testing brake fluid. Because they cannot realistically simulate the state of brake fluid in the automotive operating environment, the test results may not accurately reflect the performance of brake fluid in actual use. This may lead to misjudgment of brake fluid quality, thereby affecting the vehicle's safety performance. Accurate test data is crucial for the research and optimization of brake fluid. If the testing device cannot provide a realistic simulation environment, then researchers will find it difficult to make effective formula adjustments and performance improvements based on the test results, thereby reducing research and development efficiency.

[0004] Therefore, this utility model proposes a vehicle brake fluid evaporation performance testing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for testing the evaporation performance of vehicle brake fluid.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a vehicle brake fluid evaporation performance testing device, comprising:

[0007] The chamber and the evaporation detection box installed inside the chamber, the evaporation detection box is provided with an oil filling connector, and an exhaust connector is provided on the side of the evaporation detection box away from the oil filling connector;

[0008] A rocking assembly is placed inside a housing. The rocking assembly includes a first support frame fixed inside the housing near the bottom. A first drive motor is mounted on the first support frame. A first drive wheel is fixedly connected to the output end of the first drive motor. A belt is provided on the first drive wheel. A second drive wheel is provided on the belt. A first rotating block is fixedly connected to the second drive wheel. A second support frame is rotatably connected to the first rotating block. A first rotating rod is rotatably connected to the second support frame. One end of the first rotating rod away from the second support frame is rotatably connected to the first support frame. A support plate is fixedly connected to the top of the second support frame.

[0009] A clamping and fixing assembly is placed on one side of the bottom of the support plate. The clamping and fixing assembly includes a second drive motor installed on one side of the bottom of the support plate. A second rotating block is fixedly connected to the output end of the second drive motor. A second rotating rod is rotatably connected to the second rotating block. A connecting block is rotatably connected to one end of the second rotating rod away from the second rotating block. A clamping plate is provided on the side of the connecting block near the evaporation detection box.

[0010] Furthermore, the first transmission wheel is rotatably connected to the first support frame, and the second transmission wheel is rotatably connected to the first support frame.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, since the first transmission wheel is rotatably connected to the first support frame and the second transmission wheel is rotatably connected to the first support frame, the first transmission wheel and the second transmission wheel can rotate freely relative to the first support frame.

[0012] Furthermore, a damping rod is fixedly connected to the side of the connecting block near the evaporation detection box, and the clamping plate is fixedly connected to the damping rod.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, since a damping rod is fixedly connected to the side of the connecting block near the evaporation detection box, the damping rod is used to support and position the clamping plate. Since the clamping plate is fixedly connected to the damping rod, the clamping plate is connected to the connecting block through the damping rod, thereby applying pressure to the evaporation detection box and maintaining its stability.

[0014] Furthermore, a telescopic spring is provided on the damping rod, one end of which is fixedly connected to the connecting block, and the other end of which is fixedly connected to the clamping plate.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: Since the damping rod is equipped with a telescopic spring, the telescopic spring is used to provide elastic force to assist the clamping action. Since one end of the telescopic spring is fixedly connected to the connecting block and the other end of the telescopic spring is fixedly connected to the clamping plate, the two ends of the telescopic spring are respectively connected to the connecting block and the clamping plate, forming an elastic system, which can provide a buffering effect during the clamping process and reduce the impact on the evaporation detection box.

[0016] Furthermore, a limiting groove is provided on the support plate, and the connecting block is slidably connected in the limiting groove.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the connecting block makes precise linear movement within the limiting groove on the support plate, thereby ensuring that the clamping plate can accurately clamp and fix the evaporation detection box. At the same time, the limiting groove can also prevent the connecting block from unnecessary displacement or rotation during operation, thereby improving the stability and reliability of the entire device.

[0018] Furthermore, a lid is rotatably connected to the top of the box.

[0019] The beneficial effect of adopting the above-mentioned further solution is that it allows operators to easily open the cover of the vehicle brake fluid evaporation performance testing device, thereby accessing the evaporation testing box and its related components, while maintaining the sealing and protection of the equipment.

[0020] Furthermore, a card holder is fixedly connected to the box body, and a card block is fixedly connected to the side of the box cover near the card holder, with the card block disposed inside the card holder.

[0021] The beneficial effect of adopting the above-mentioned further solution is that when the lid needs to be closed, the operator aligns the locking block with the locking seat, and then presses down or rotates the lid to make the locking block enter the locking seat. Once the locking block is fully in the locking seat, it will lock in the proper position, ensuring that the lid is firmly fixed to the box body and preventing accidental opening.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, the swaying assembly drives the first transmission wheel to rotate via a first transmission motor, which in turn drives the second transmission wheel on the belt to rotate. The second transmission wheel is fixedly connected to the first rotating block, causing the first rotating block to rotate as well. Since one end of the first rotating rod is rotatably connected to the first support frame and the other end is rotatably connected to the second support frame, when the first rotating block rotates, it will drive the second support frame and its top support plate to sway, causing the evaporation detection box fixed above the support plate to sway. The swaying motion generated by the swaying assembly helps to simulate the dynamic environment under actual use conditions. In this way, the evaporation rate of vehicle brake fluid under different conditions can be detected more accurately. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1-4 As shown, this embodiment provides a technical solution: a vehicle brake fluid evaporation performance testing device, comprising:

[0035] The housing 1 and the evaporation detection box 2 installed inside the housing 1 are provided with an oil filling connector 5 and an exhaust connector 6 on the side of the evaporation detection box 2 away from the oil filling connector 5.

[0036] The rocking assembly 3 is placed inside the housing 1. The rocking assembly 3 includes a first support frame 31 fixed inside the housing 1 near the bottom. A first drive motor 32 is mounted on the first support frame 31. A first drive wheel 33 is fixedly connected to the output end of the first drive motor 32. A belt 34 is provided on the first drive wheel 33. A second drive wheel 35 is provided on the belt 34. A first rotating block 36 is fixedly connected to the second drive wheel 35. A second support frame 37 is rotatably connected to the first rotating block 36. A first rotating rod 38 is rotatably connected to the second support frame 37. One end of the first rotating rod 38 away from the second support frame 37 is rotatably connected to the first support frame 31. A support plate 39 is fixedly connected to the top of the second support frame 37.

[0037] The clamping and fixing assembly 4 is located on one side of the bottom of the support plate 39. The clamping and fixing assembly 4 includes a second drive motor 41 mounted on one side of the bottom of the support plate 39. A second rotating block 42 is fixedly connected to the output end of the second drive motor 41. A second rotating rod 43 is rotatably connected to the second rotating block 42. A connecting block 44 is rotatably connected to one end of the second rotating rod 43 away from the second rotating block 42. A clamping plate 46 is provided on the side of the connecting block 44 near the evaporation detection box 2. The swing assembly 3 drives the first drive wheel 33 to rotate via the first drive motor 32, thereby driving the second drive wheel 35 on the belt 34 to rotate. The second drive wheel 35 is fixedly connected to the first rotating block 36, causing the first rotating block 36 to rotate as well. Since one end of the first rotating rod 38 is rotatably connected to the first support frame 31, and the other end is connected to the second support... The support frame 37 is rotatably connected, so when the first rotating block 36 rotates, it will drive the second support frame 37 and its top support plate 39 to swing, causing the evaporation detection box 2 fixed above the support plate 39 to swing. The swinging motion generated by the swing assembly 3 helps to simulate the dynamic environment under actual use conditions. In this way, the evaporation rate of vehicle brake fluid under different conditions can be detected more accurately. The second drive motor 41 is started, and the second drive motor 41 drives the second rotating block 42 to rotate, which in turn drives the second rotating rod 43 to rotate. The other end of the second rotating rod 43 is rotatably connected to the connecting block 44. A clamping plate 46 is provided on the side of the connecting block 44 near the evaporation detection box 2. As the second rotating rod 43 rotates, the clamping plate 46 will apply pressure to the evaporation detection box 2, thereby achieving clamping and fixing of the evaporation detection box 2.

[0038] The above solutions also have the problem that the evaporation detection box 2 cannot be fixed in place when it is in a swinging motion, such as... Figures 1-3As shown: the first transmission wheel 33 is rotatably connected to the first support frame 31, and the second transmission wheel 35 is rotatably connected to the first support frame 31. Since the first transmission wheel 33 is rotatably connected to the first support frame 31, and the second transmission wheel 35 is rotatably connected to the first support frame 31, the first transmission wheel 33 and the second transmission wheel 35 can rotate freely relative to the first support frame 31.

[0039] like Figure 2 as well as Figure 4 As shown, a damping rod 45 is fixedly connected to the side of the connecting block 44 near the evaporation detection box 2, and a clamping plate 46 is fixedly connected to the damping rod 45. Because the damping rod 45 is fixedly connected to the side of the connecting block 44 near the evaporation detection box 2, the damping rod 45 supports and positions the clamping plate 46. Since the clamping plate 46 is fixedly connected to the damping rod 45, it is connected to the connecting block 44 via the damping rod 45, thus applying pressure to the evaporation detection box 2 and maintaining its stability. A telescopic spring 47 is provided on the damping rod 45. One end of the telescopic spring 47 is fixedly connected to the connecting block 44, and the other end is fixedly connected to the clamping plate 46. Because the telescopic spring 47 is provided on the damping rod 45, it provides elastic force to assist the clamping plate 46. During the holding action, since one end of the telescopic spring 47 is fixedly connected to the connecting block 44 and the other end of the telescopic spring 47 is fixedly connected to the clamping plate 46, the two ends of the telescopic spring 47 are respectively connected to the connecting block 44 and the clamping plate 46, forming an elastic system, which can provide a buffering effect during the clamping process and reduce the impact on the evaporation detection box 2. A limiting groove 48 is opened on the support plate 39, and the connecting block 44 is slidably connected in the limiting groove 48. The connecting block 44 performs precise linear movement in the limiting groove 48 on the support plate 39, thereby ensuring that the clamping plate 46 can accurately clamp and fix the evaporation detection box 2. At the same time, the limiting groove 48 can also prevent the connecting block 44 from unnecessary displacement or rotation during operation, improving the stability and reliability of the entire device.

[0040] like Figure 1 As shown, a cover 7 is rotatably connected to the top of the housing 1. In the vehicle brake fluid evaporation performance testing device, this allows the operator to easily open the cover 7 to access the evaporation test box 2 and its related components, while maintaining the equipment's airtightness and protection. A retainer 8 is fixedly connected to the housing 1, and a retaining block 9 is fixedly connected to the side of the cover 7 near the retainer 8. The retaining block 9 is located inside the retainer 8. When the cover 7 needs to be closed, the operator aligns the retaining block 9 with the retainer 8 and then presses down or rotates the cover 7 to allow the retaining block 9 to enter the retainer 8. Once the retaining block 9 is fully inside the retainer 8, it locks in place, ensuring that the cover 7 is securely fixed to the housing 1 and preventing accidental opening.

[0041] like Figures 1-4As shown, firstly, the evaporation detection box 2 is placed in the slot opened on the support plate 39. Then, the second drive motor 41 is started, which drives the second rotating block 42 to rotate, thereby driving the second rotating rod 43 to rotate. The other end of the second rotating rod 43 is rotatably connected to the connecting block 44. A clamping plate 46 is provided on the side of the connecting block 44 near the evaporation detection box 2. As the second rotating rod 43 rotates, the clamping plate 46 applies pressure to the evaporation detection box 2. Through the cooperation of the damping rod 45 and the telescopic spring 47, a buffering effect can be provided during the clamping process to reduce the impact on the evaporation detection box 2, thereby achieving the clamping and fixing of the evaporation detection box 2. Subsequently, the swing assembly 3 drives the first drive wheel 33 to rotate through the first drive motor 32, thereby driving the second drive wheel 35 on the belt 34 to rotate. The second drive wheel 35 and the first rotating block 36 are connected. The fixed connection causes the first rotating block 36 to rotate as well. Since one end of the first rotating rod 38 is rotatably connected to the first support frame 31 and the other end is rotatably connected to the second support frame 37, when the first rotating block 36 rotates, it will drive the second support frame 37 and its top support plate 39 to swing, causing the evaporation detection box 2 fixed above the support plate 39 to swing. The swinging motion generated by the swing assembly 3 helps to simulate the dynamic environment under actual use conditions. In this way, the evaporation rate of vehicle brake fluid under different conditions can be detected more accurately. When the cover 7 needs to be closed, the operator aligns the locking block 9 with the locking seat 8 and then presses down or rotates the cover 7 to make the locking block 9 enter the locking seat 8. Once the locking block 9 is fully in the locking seat 8, it will lock in the appropriate position to ensure that the cover 7 is firmly fixed to the box 1 and prevent accidental opening.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
