Description

Technical Field

[0001] The present invention relates to the field of headrest force measuring equipment, and particularly to an automobile headrest force measuring machine. Background Art

[0002] During the production of automobile headrests, spot checks are required. When performing spot checks, it is necessary to measure the force of the headrests. When measuring the force, it is necessary to test through a static strength testing machine for automobile seat headrests. However, the existing static strength testing machines for automobile seat headrests on the market require auxiliary positioning devices, and the operation steps are cumbersome and prone to errors. Due to the poor definition of the proximity of the headrest gap measurement position.

[0003] According to a semi-automatic three-station headrest static strength testing machine disclosed in a patent document with the existing publication number of 208636139U, it includes a reference point H-point device installed on the seat to be tested and connected to the main body of the headrest testing machine through a connecting fork. The reference point H-point device can be quickly connected / unlocked to the rotary pivot of the rotary beam and the L-shaped main beam. The left middle side of the rotary beam is hinged to the push rod on the backboard loading electric cylinder. The L-shaped main beam is installed on the main body lifting adjustment mechanism and its bottom plate through a slide rail and a station spacing adjustment mechanism. When this technical solution is used, it has strong practicability and accuracy. By pre-engraving dimension lines and numbers at relevant parts of each component, the dimensions can be directly read during the measurement process without manual measurement, thus saving time and improving accuracy. For the above technical solution, although the accuracy is improved, the overall device cannot be quickly disassembled and installed during use.

[0028] In this embodiment, a chute 23 is formed in the fixed seat 2. A displacement mechanism 24 is fixedly installed inside the chute 23. The displacement mechanism 24 is a linear reciprocating electric push rod. The electric push rod drives the overall horizontal movement of the movable seat 5 through a slider 25. The movement of the movable seat 5 adjusts the position of the headrest 40. One end of the displacement mechanism 24 is fixed with a slider 25. One end of the slider 25 is fixed to the bottom of the movable seat 5. An installation hole 20 is formed in the side of the base 1. An opening 19 is formed at one end of the installation hole 20. A fixed column 21 is rotatably installed inside the installation hole 20. A limit disk 22 is fixed to one end of the fixed column 21. The limit disk 22 is movably matched with one end of the fixed rod 4. A limit block 26 is fixed to the side of the fixed rod 4. A limit groove is formed in the inner wall of the fixed groove 3. The limit block 26 is installed inside the limit groove through a support mechanism 27. The support mechanism 27 is a support spring. The support spring pushes the fixed rod 4 to move outwards. The fixed rod 4 is matched with the fixed column 21 and the limit disk 22 to limit and fix the base 1.

[0029] In this embodiment, a lifting mechanism 29 is fixedly installed inside the movable seat 5. The lifting mechanism 29 is a linear reciprocating electric push rod. The electric push rod cooperates with the connecting lug 32 to tilt one end of the support seat 8, thereby adjusting the inclination angle of the support seat 8 and the headrest 40. A through hole 30 is formed in the lifting mechanism 29. A rotating shaft 31 is movably installed inside the through hole 30. A connecting lug 32 is installed on the rotating shaft 31. The connecting lug 32 is welded to the bottom of the support seat 8. A fixed lug 34 is welded on the movable seat 5. A support lug 33 is fixed to the bottom of the support seat 8. A connecting shaft 35 is rotatably installed between the support lug 33 and the fixed lug 34. The fixing assembly 10 includes a fixed block 36 and a movable block 37. A fixing bolt 41 is rotatably installed on the fixed block 36. One end of the fixing bolt 41 is rotatably installed inside the fixing hole 9. An installation groove 38 is formed between the fixed block 36 and the movable block 37. A support column 39 is movably installed inside the installation groove 38. A headrest 40 is fixed to one end of the support column 39. A clamping block 43 is fixed to the inner wall of the installation groove 38. A clamping groove is formed on the support column 39. The clamping block 43 cooperates with the clamping groove. A positioning column 42 is fixed to the side of the movable block 37. A connecting groove 44 is formed in the fixed block 36. A reset mechanism 46 is fixed inside the connecting groove 44. One end of the reset mechanism 46 is fixed to a connecting block 45. One end of the connecting block 45 is fixed to the movable block 37. The reset mechanism 46 is a reset spring. The reset spring pushes the movable block 37 towards the fixed block 36. The clamping block 43 on the inner wall of the movable block 37 enters the clamping groove on the side of the support column 39 to limit and fix the entire support column 39.

[0030] When in use, the device adjusts the installation position of the fixing component 10 according to the gaps between the support columns 39 on the batch headrests 40. The fixing block 36 on the fixing component 10 is fixedly installed inside the fixing hole 9 through the fixing bolt 41 for limit fixation. After the fixing component 10 is fixedly installed, the movable block 37 is moved to one side. While the connecting block 45 on the movable block 37 moves inside the connecting groove 44, the reset mechanism 46 is stretched and deformed. After the support column 39 is installed inside the installation groove 38, the movable block 37 is released. The tensile force generated by the reset mechanism 46 causes the movable block 37 to move towards the position of the fixing block 36. After the movable block 37 returns to its position, the latch 43 enters the internal card slot on the side of the support column 39 to limit the support column 39. After the support column 39 is limited, the position of the headrest 40 is determined. The displacement mechanism 24 is started to drive the slider 25 to move inside the sliding groove 23, and the position of the entire movable seat 5 is adjusted by moving, so that the headrest 40 on the movable seat 5 is vertically aligned with the extrusion seat 18 up and down. After alignment, the power mechanism 17 and the hydraulic mechanism 16 are started to work. The power mechanism 17 drives the mounting seat 15 to move downward. After the mounting seat 15 moves downward to an appropriate height, the hydraulic mechanism 16 pushes the extrusion seat 18 to continue moving downward. After the extrusion seat 18 contacts the headrest 40, pressure is applied, and the pressure is used to test the force-bearing condition of the headrest 40. Before the test, the support seat 8 is tilted according to requirements. After the support seat 8 is tilted, the force-bearing condition of the simulated automobile seat and the tilted state of the headrest 40 is tested. The lifting mechanism 29 is started to move upward. When the lifting mechanism 29 rises, it rotates inside the connecting lug 32 through the rotating shaft 31. Driven by the lifting mechanism 29, one end of the support seat 8 tilts upward. While tilting upward, the rotating column 28 slides inside the arc-shaped groove 7. The support seat 8 rotates and tilts on the fixed lug 34 through the support lug 33. The cooperation of the fixed lug 34 and the support lug 33 provides a support and fixation point for the rotation of the support seat 8. After the support seat 8 and the headrest 40 are tilted, the movable seat 5 moves to adjust the corresponding positions of the headrest 40 and the extrusion seat 18 for convenient later extrusion use. During extrusion, observe whether the support column 39 is deformed under force, so as to test the force-bearing limit.
