Description

Technical Field

[0001] This invention relates to the field of automotive testing technology, and more particularly to an automotive braking force testing device. Background Technology

[0002] An automotive braking system refers to a series of specialized devices that apply a certain force to certain parts of a vehicle, thereby forcibly braking it to a certain extent. The functions of the braking system are: to forcibly decelerate or even stop a moving vehicle according to the driver's requirements; to keep a parked vehicle stable under various road conditions; and to maintain a stable speed for a vehicle traveling downhill. The braking system needs to be tested to ensure its effectiveness.

[0003] Chinese patent CN103308236B discloses an auxiliary device for automotive testing equipment in the automotive industry, namely a wheel constraint device for automotive bench braking force testing. It aims to solve the problem that the tested vehicle is in an unstable state in the existing automotive bench braking force testing, resulting in large errors in braking force testing. The device consists of a constraint roller mechanism, a lifting hydraulic system, and a positioning hydraulic system. The constraint roller applies a horizontal forward constraint to the test wheel, so that the test vehicle is in a stable state. The lifting and positioning hydraulic systems are connected in a "V" shape by a connecting arm, which can realize the free movement of the constraint roller in a two-dimensional plane.

[0004] However, the existing testing process can only detect braking when pressure is applied to the wheel, and cannot detect the braking effect of the wheel under different road conditions, which can easily lead to errors in the detection of braking effect. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies that can only detect braking when pressure is applied to the wheel, but cannot detect the braking effect of the wheel under different road conditions, which easily leads to detection errors in braking effect. Therefore, this invention proposes an automotive braking force detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vehicle braking force testing device includes: a testing platform, which is a rectangular platform with two symmetrical rotating slots at one end;

[0008] The detection platform has a sliding groove in the middle, and a drive assembly is slidably connected to the middle of the detection platform via a sliding component. The drive assembly includes a mounting block, a drive module, a braking module, a drive shaft, and detection wheels. The mounting block is fixedly connected to the sliding component and has a rotating opening in the middle. The drive shaft is rotatably mounted inside the rotating opening. The two detection wheels are fixedly connected to both ends of the drive shaft and located inside the rotating groove. The braking module is fixedly connected to the upper end of the mounting block for braking the drive shaft. The two drive modules are symmetrically fixedly connected to both sides of the mounting block and sleeved on the drive shaft.

[0009] The testing platform is fixedly connected to a placement assembly at one end near the rotating groove. The placement assembly includes a base plate, side frames, and a middle frame. The base plate is fixedly connected to the bottom side of the end of the testing platform. Multiple side frames are symmetrically fixedly connected to both sides of the base plate away from the testing platform. Multiple middle frames are fixedly connected to the middle of the base plate and located between two side frames.

[0010] A simulated floor is provided between the side frame and the middle frame. Multiple simulated floors are made of different materials and are used to test the braking effect of the car under different conditions. The simulated floor has a threaded groove in the middle and pull rings are symmetrically fixed to both sides of the upper end.

[0011] Preferably, a pushing component is provided at the end of the detection platform away from the rotating groove. The pushing component is used to push the drive component to move and apply pressure to the detection wheel.

[0012] Preferably, the pushing component includes a control module, an operation panel, and a pushing rod. The control module is fixedly installed at the end of the detection table, the operation panel is fixedly connected to the side of the control module, and one end of the pushing rod is horizontally fixedly connected to the side of the control module near the driving component, while the other end is fixedly connected to the side of the mounting block.

[0013] Preferably, the sliding assembly includes a sliding block and a pad, the pad being fixedly connected to the bottom of the mounting block, the sliding block being fixedly connected to the bottom of the pad, and slidably disposed inside the groove.

[0014] Preferably, the placement assembly further includes a fixing frame, a baffle, and a telescopic column. The fixing frame is fixedly connected to the side of the base plate near the testing table, the telescopic column is horizontally fixedly connected to the inside of the fixing frame, and the baffle is fixedly connected to the end of the telescopic column.

[0015] Preferably, the fixing frame is U-shaped with its opening facing the testing table, and a limiting component is provided on the side of the fixing frame to limit the position of the simulated floor.

[0016] Preferably, the limiting component includes an elastic plate and a limiting plate. The end of the fixing frame has a groove, and the limiting plate is fixedly installed inside the groove. The limiting plate is fixedly connected to the end of the elastic plate and is L-shaped to fix the position of the simulated floor.

[0017] Preferably, a locking component is installed at the upper end of the fixing frame, the locking component being used to fix the vertical position of the simulated floor.

[0018] Preferably, the locking assembly includes a rotating column, an elastic plate, a threaded column, and a locking block.

The locking block is fixedly connected to the bottom end of the threaded column and is used for threaded connection of the simulated floor.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. During the testing process, the drive module drives the drive shaft to rotate, and the braking module applies pressure to brake the drive shaft.

This invention can perform braking tests on automobiles under various conditions, reducing testing errors and improving the accuracy of braking tests.

[0021] 2. Data is adjusted via the control panel, which causes the control module to push the push rod to push the mounting block, and applies pressure to the detection wheel according to the push rod, which is used to represent the vehicle body with different gravity.

[0023] 4. The elastic plate drives the limiting plate to clamp and fix different simulated flooring, which ensures the position of the simulated flooring and the stability of the simulated flooring when it moves. Attached Figure Description

Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0032] Reference Figures 1-5 A vehicle braking force testing device includes: a testing platform 1, which is a rectangular platform with two symmetrical rotating slots at one end;

[0033] The testing platform 1 has a sliding groove in the middle. The driving assembly 3 is slidably connected to the middle of the testing platform 1 through the sliding assembly 2. The driving assembly 3 includes a mounting block 31, a driving module 32, a braking module 33, a driving shaft 34, and a testing wheel 35. The mounting block 31 is fixedly connected to the sliding assembly 2 and has a rotating opening in the middle. The driving shaft 34 is rotatably installed inside the rotating opening. The two testing wheels 35 are fixedly connected to both ends of the driving shaft 34 and are located inside the rotating groove. The braking module 33 is fixedly connected to the upper end of the mounting block 31 and is used to brake the driving shaft 34. The two driving modules 32 are symmetrically fixedly connected to both sides of the mounting block 31 and are sleeved on the driving shaft 34.

[0034] The testing table 1 is fixedly connected to a placement component 4 at one end near the rotating groove. The placement component 4 includes a base plate 41, side frames 42 and a middle frame 43. The base plate 41 is fixedly connected to the bottom side of the end of the testing table 1. Multiple side frames 42 are symmetrically fixedly connected to both sides of the base plate 41 away from the testing table 1. Multiple middle frames 43 are fixedly connected to the middle of the base plate 41 and are located between two side frames 42.

[0035] A simulated floor 5 is provided between the side frame 42 and the middle frame 43. Multiple simulated floors are made of different materials and are used to test the braking effect of the car under different conditions. The simulated floor 5 has a threaded groove in the middle and pull rings are symmetrically fixed to both sides of the upper end.

[0036] In the embodiments of the above technical solution, during the detection process, the drive module 32 drives the drive shaft 34 to rotate, and the braking module 33 applies pressure to brake the drive shaft 34. Multiple simulated floorboards 5 with different friction forces are placed inside the placement component 4. Based on the effects of the various simulated floorboards 5 on the braking process of the detection wheel 35, the detection effect of the detection wheel 35 under various different conditions is tested. The present invention can perform braking tests on automobiles under various conditions, reducing detection errors and improving the accuracy of braking tests.

[0037] In this preferred embodiment, a pushing component 6 is provided at the end of the detection table 1 away from the rotating groove. The pushing component 6 is used to push the drive component 3 to move and apply pressure to the detection wheel 35.

[0038] The pushing component 6 includes a control module 61, an operation panel 62, and a pushing rod 63. The control module 61 is fixedly installed at the end of the detection table 1. The operation panel 62 is fixedly connected to the side of the control module 61. One end of the pushing rod 63 is horizontally fixedly connected to the side of the control module 61 near the driving component 3, and the other end is fixedly connected to the side of the mounting block 31. Data is adjusted through the operation panel 62, so that the control module 61 pushes the pushing rod 63 to push the mounting block 31. The pushing rod 63 applies pressure to the detection wheel 35 to represent the vehicle body with different gravity.

[0039] The sliding component 2 includes a sliding block 21 and a pad 22. The pad 22 is fixedly connected to the bottom of the mounting block 31, and the sliding block 21 is fixedly connected to the bottom of the pad 22 and is slidably disposed inside the groove. By pushing the component 6, the mounting block 31 is driven to slide, so that the sliding block 21 slides inside the groove, thereby reducing the friction generated by the movement of the driving component 3.

[0040] The placement component 4 also includes a fixed frame 44, a baffle 45, and a telescopic column. The fixed frame 44 is fixedly connected to the side of the base plate 41 near the test table 1. The telescopic column is horizontally fixedly connected to the inside of the fixed frame 44. The baffle 45 is fixedly connected to the end of the telescopic column. During the testing process using the simulated floor 5, the simulated floor 5 to be used is placed inside the fixed frame 44. The telescopic column drives the baffle 45 to push the simulated floor 5, ensuring that the test wheel 35 contacts the simulated floor 5.

[0041] The fixing frame 44 is U-shaped and the opening faces the testing table 1. The fixing frame 44 is provided with a limit component 7 on the side. The limit component 7 is used to limit the position of the simulated floor 5.

[0042] The limiting component 7 includes an elastic plate 71 and a limiting plate 72. The end of the fixing frame 44 has a groove, and the limiting plate 72 is fixedly installed inside the groove. The limiting plate 72 is fixedly connected to the end of the elastic plate 71 and is L-shaped, used to fix the position of the simulated floor 5. The elastic plate 71 drives the limiting plate 72 to clamp and fix different simulated floor 5, ensuring the position restriction of the simulated floor 5 and ensuring the stability of the simulated floor 5 when it moves.

[0043] A locking component 8 is installed on the upper end of the fixing bracket 44. The locking component 8 is used to fix the vertical position of the simulated floor 5.

[0044] The locking assembly 8 includes a rotating column 81, a telescopic plate 82, a threaded column 83, and a locking block 84. The rotating column 81 is rotatably mounted on the upper middle part of the fixed frame 44. The telescopic plate 82 is horizontally fixedly connected to the upper end of the rotating column 81. The threaded column 83 is threadedly connected to the other end of the telescopic plate 82. The locking block 84 is fixedly connected to the bottom end of the threaded column 83 and is used for threaded connection to the simulated floor 5. By rotating the threaded column 83, the locking block 84 is driven to move downward, thereby making the locking block 84 fit into the threaded groove at the upper end of the simulated floor 5.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
