Description

Technical Field

[0001] The present invention relates to the detection technology of automobile instrument covers, and particularly to a compressive strength testing device for automobile instrument covers. Background Art

[0002] With the rapid development of the automobile industry, more and more functions need to be realized by automobile instruments. The results of function outputs on the automobile instrument are usually displayed to users through the liquid crystal display screen on the automobile instrument.

[0003] A shielding cover is usually provided on the liquid crystal display screen of the automobile instrument to better protect the liquid crystal display screen. After the production of the automobile instrument shielding cover is completed, it is necessary to conduct a hardness and compressive strength test on the automobile instrument shielding cover so that the automobile instrument shielding cover can better meet the required hardness and facilitate the better protection of the liquid crystal display screen by the automobile instrument shielding cover.

[0004] In the Chinese invention patent with the publication number CN218349983U, a hardness and compressive strength detection test device for an automobile instrument shielding cover is disclosed. In this device, an anti-slip pad is fixedly connected to the bottom of the base, which facilitates better placement of the base through the anti-slip pad, so that the base is not prone to sliding during use. Sliding grooves are respectively opened at the front and rear of the top of the base, which facilitates the movable clamping of the slider inside the sliding grooves. At this time, the slider can move left and right inside the sliding grooves, and at the same time, the slider can drive the support sleeve to move. A support plate is movably inserted inside the support sleeve, which facilitates the up and down movement of the support plate inside the support sleeve. At this time, under the action of the bolt, the position of the support plate can be positioned. A screw rod is rotatably connected inside the through groove, which facilitates the movement of the limit block through the screw rod. At this time, the limit block drives the electric push rod and the hardness meter to adjust the front and rear positions, and at the same time, the position of the hardness meter can be adjusted under the action of the electric push rod.

[0005] When the existing equipment is in use, it is unable to simulate diverse actual environments and collision situations, which leads to a difference between the detection result of the compressive performance of the cover and the envisioned state. At the same time, during the detection, the stability of the cover is poor, so that the cover is prone to sliding during the compressive strength test, resulting in deviation of the detection result. Therefore, a compressive strength testing device for automobile instrument covers is developed. Summary of the Invention

[0036] Embodiment: Please refer to Figures 1-8 , an anti-compression test device for an automotive instrument panel cover, including a base 1. A protective cylinder 11 is fixedly installed at the upper end of the base 1, and an adjustment column 12 is rotatably installed at the upper end of the base 1. A detection component 3 is fixedly installed at the end of the adjustment column 12, and the mask is subjected to a bump test through the detection component 3.

[0037] In this solution, the cross-section of the adjustment column 12 is L-shaped. At the same time, devices with power output such as a motor are provided at the lower end of the adjustment column 12 and are connected to an external control device. When the motor is started, the adjustment column 12 is driven to rotate, and the detection component 3 fixedly installed at the end of the adjustment column 12 is driven to move until it stops at the designated position.

[0038] Furthermore, the detection component 3 includes a clamping block 31 fixedly connected to the adjustment column 12. An elastic member 32 is fixedly installed at the end of the clamping block 31. At the same time, a positioning plate 33 is fixedly installed at the end of the elastic member 32. A rotating cylinder 331 is fixedly installed at the end of the positioning plate 33. A plurality of arc-shaped plates 34 are rotatably installed on the outer surface of the rotating cylinder 331, and the plurality of arc-shaped plates 34 are evenly distributed on the outer surface of the rotating cylinder 331.

[0039] In this embodiment, the elastic member 32 is composed of a telescopic rod and a spring. The spring is sleeved on the outer surface of the telescopic rod, and the two ends of the spring are respectively connected to the ends of the clamping block 31 and the positioning plate 33.

[0040] Devices with power output such as a motor are provided at the end of the positioning plate 33, and the output end of the motor is fixedly connected to the end of the rotating cylinder 331. When the motor is started, the rotating cylinder 331 is synchronously driven to rotate, and the arc-shaped plates 34 rotatably installed on the outer surface of the rotating cylinder 331 are used to impact the mask.

[0041] Further, a sleeve 35 is fixedly installed on the inner wall of the rotary drum 331. A sliding groove 37 corresponding to the arc-shaped plate 34 is formed on the inner wall of the sleeve 35. A slider 371 is slidably installed on the inner wall of the sliding groove 37. An end of the slider 371 is fixedly installed with a driving rod 39. The end of the driving rod 39 sequentially penetrates through the sleeve 35 and the rotary drum 331 and extends to the outer surface of the rotary drum 331. The end of the driving rod 39 is slidably connected to the inner wall of the arc-shaped plate 34.

[0042] Specifically, when the slider 371 moves, it synchronously drives the driving rod 39 fixedly installed at its end to move. Since the end of the driving rod 39 is slidably connected to the inner wall of the arc-shaped plate 34, the driving rod 39 drives the arc-shaped plate 34 to rotate around the connection with the outer surface of the rotary drum 331 until the arc-shaped plate 34 is adjusted to a suitable position and then stops.

[0043] A torsion spring is arranged at the connection between the arc-shaped plate 34 and the rotary drum 331. When the driving rod 39 contracts, the arc-shaped plate 34 is restored to its initial position by the acting force of the torsion spring.

[0044] Further, a turntable 36 is rotatably installed at the middle position of the inner wall of the sleeve 35. A moving rod 361 corresponding to the slider 371 is rotatably installed on the outer surface of the turntable 36. One end of the moving rod 361 away from the turntable 36 is rotatably connected to the end of the slider 371. An end of the slider 371 is fixedly installed with a driving member 38. The output end of the driving member 38 is fixedly connected to the end of another slider 371.

[0045] Specifically, the driving member 38 is a device with a telescopic function such as an electric telescopic rod and is connected to an external control device. At the same time, when the driving member 38 is started, it synchronously drives the slider 371 fixedly installed at its output end to move. The slider 371 is limited by the sliding groove 37, so that when the slider 371 is stressed, it moves along the inner wall of the sliding groove 37 as a whole.

[0046] When the slider 371 moves, it synchronously drives the moving rod 361 rotatably installed at its end to move. The cross section of the moving rod 361 is L-shaped. When the moving rod 361 moves, it drives the turntable 36 to rotate, thereby cooperatively driving other moving rods 361 to move, realizing the synchronous movement of multiple moving rods 361, and further adjusting the angle of the arc-shaped plate 34 to make it suitable for collision detection with different forces.

[0047] Further, an annular groove 14 is formed at the upper end of the fixed plate 13. A movable assembly 4 is slidably installed on the inner wall of the annular groove 14. The movable assembly 4 simulates torsion to detect the face mask; the movable assembly 4 includes a movable plate 41 slidably connected to the inner wall of the annular groove 14. An end of the movable plate 41 is fixedly installed with a ring 43. Swing blocks 44 are symmetrically and rotatably installed on the inner wall of the ring 43.

[0048] In this embodiment, devices with power output such as motors are arranged on the inner wall of the annular groove 14. A convex block is arranged on the outer surface of the output end of the motor. Meanwhile, an annular block is rotatably installed on the inner wall of the annular groove 14, and the outer surface of the annular block meshes with the outer surface of the convex block. Thus, when the motor is started, the annular block is driven to rotate on the inner wall of the annular groove 14.

[0049] The lower end of the movable plate 41 is fixedly connected to the end of the annular block. Thus, when the annular block moves, the movable assembly 4 is synchronously driven to move until it stops at the optimal position.

[0050] Furthermore, a power member 42 is fixedly installed on one side of the movable plate 41. The output end of the power member 42 penetrates and extends into the interior of the circular ring 43. Meanwhile, the output end of the power member 42 is fixedly connected to the end of the swing block 44.

[0051] Specifically, the power member 42 is a device with power output such as a motor and is connected to an external control device. Meanwhile, when the power member 42 is started, the swing block 44 arranged at its output end is synchronously driven to rotate.

[0052] Furthermore, guiding grooves 46 are symmetrically formed inside the circular ring 43. A guiding block 47 is slidably installed on the inner wall of the guiding groove 46. A cross rod 45 is rotatably installed at the end of the guiding block 47. Adjacent ends of the cross rod 45 are respectively rotatably connected to the ends of the symmetrically arranged swing blocks 44. A pressing block 48 is fixedly installed at the end of the guiding block 47 away from the cross rod 45. The side surface of the face mask is pressure - tested through the pressing block 48.

[0053] Specifically, when the swing block 44 rotates, the cross rod 45 fixedly installed at its end is synchronously driven to swing. Since both adjacent ends of the cross rod 45 are rotatably connected to the guiding block 47, when the cross rod 45 is stressed and swings, the guiding block 47 is driven to reciprocate on the inner wall of the guiding groove 46.

[0054] The pressing block 48 is fixedly installed on the guiding block 47. Thus, the pressing block 48 moves synchronously with the guiding block 47. When the two pressing blocks 48 move synchronously, a torsional pressure test is performed on the face mask located between the two pressing blocks 48.

[0055] Furthermore, a fixing plate 13 is fixedly installed at the upper end of the adjusting column 12. A limiting component 2 is fixedly installed at the upper end of the fixing plate 13. The face mask is limited through the limiting component 2. The limiting component 2 includes a bottom plate 21 fixedly connected to the fixing plate 13. An adjusting disk 22 is rotatably installed at the end of the bottom plate 21. A push rod 23 is rotatably installed at the end of the adjusting disk 22 and away from the center of the circle.

[0056] In this embodiment, a device with power output such as a motor is provided at the end of the adjusting disk 22 and is connected to an external control device. The end of the motor is fixedly connected to the bottom plate 21. When the motor is started, it drives the adjusting disk 22 to rotate, and at the same time, when the adjusting disk 22 rotates, it drives the push rod 23 rotatably installed at its end to move.

[0057] Furthermore, a plurality of connecting blocks 24 are fixedly installed at the end of the bottom plate 21, and the plurality of connecting blocks 24 are evenly distributed at the end of the bottom plate 21. At the same time, a limiting rod 25 is slidably installed on the inner wall of the connecting block 24. The end of the limiting rod 25 is rotatably connected to the end of the push rod 23, and the ends of adjacent two limiting rods 25 are rotatably connected by a positioning rod 26.

[0058] Specifically, when the push rod 23 moves, it drives the limiting rod 25 rotatably installed at its end to move. Since the outer surface of the limiting rod 25 is slidably connected to the inner wall of the connecting block 24, when the limiting rod 25 is stressed, it moves along the inner wall of the connecting block 24.

[0059] At the same time, adjacent two limiting rods 25 are rotatably connected by a positioning rod 26, so that when one of the limiting rods 25 moves, the adjacent two limiting rods 25 move in opposite directions, and thus the face mask can be locked.

[0060] A locking block is fixedly installed at the end of the limiting rod 25. The locking block is inclined, which is convenient for fixing the face mask, and an anti-slip component such as rubber is provided on the outer surface of the locking block, so as to strengthen the locking of the face mask.

[0061] A supporting plate 27 is fixedly installed at the upper end of the bottom plate 21, and the face mask is fixed by the supporting plate 27.

[0062] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a miniature computer. Compared with the general-purpose microprocessor applied in a personal computer, it emphasizes more on self-supply (without external hardware) and cost saving. Its greatest advantage is its small size, which can be placed inside the instrument, but its storage capacity is small, the input and output interfaces are simple, and the function consumption is low.

[0063] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
