Description

Technical Field

[0001] This utility model relates to the field of automotive seat frame processing technology, specifically to an automotive seat frame installation and positioning mechanism. Background Technology

[0002] The car seat frame is the core load-bearing structure of a car seat, equivalent to the "skeleton / frame" of the seat. It is the basic component that supports the seat foam, surface, seat belt anchor points, and adjustment mechanisms (such as slide rails and adjusters). Its main functions are to bear the weight of the human body, fix the various functional components of the seat, and transmit and disperse the impact force during a collision.

[0003] In order to ensure the stability of the car seat frame during the welding process with other parts, a car seat frame mounting and positioning mechanism is used to support the car seat frame.

[0004] Existing automotive seat frame installation and positioning mechanisms typically fix the automotive seat frame by tightening screws and using clamps. Therefore, when it is necessary to release the fixation of the automotive seat frame, it is only necessary to reverse the screws. As a result, it is very easy for the screws to be accidentally reversed during use, which in turn causes the force applied by the clamps to the automotive seat frame to loosen, causing it to shift during processing. To address this problem, we propose an automotive seat frame installation and positioning mechanism. Utility Model Content

[0005] The purpose of this invention is to provide an automotive seat frame mounting and positioning mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car seat frame mounting and positioning mechanism, comprising a positioning plate, a positioning frame bolted to the top of the positioning plate, a threaded rod disposed within the positioning frame, the threaded rod penetrating the positioning frame and rotatably connected to the positioning frame, the threaded rod penetrating a pressure plate and threadedly connected to the pressure plate, and a control component and a driven component disposed on the side of the positioning frame, the control component comprising:

[0007] A support rod, which is used to support the lateral movement of the pressure plate;

[0008] The movable block can be folded and squeezed by the triangular block inside the ring when it is resisted;

[0009] A rotating rod, which is connected to a threaded rod via a circular plate and provides driving force for the rotation of the threaded rod;

[0010] The fixing ring, with a spring-connected ring inside, provides a spring force to the ring, thereby limiting the counterclockwise rotation of the rotating rod and the circular plate, and preventing the pressure plate from shifting due to accidental reversal of the rotating rod when fixing the car seat frame.

[0011] Preferably, the support rod is fixedly installed on the side of the pressure plate, the support rod passes through the positioning frame and is slidably connected to the positioning frame, and the support rod can support the movement of the pressure plate when the pressure plate moves.

[0012] Preferably, the side of the threaded rod is fixedly connected to the circular plate, and the side of the circular plate is rotatably connected to the side of the positioning frame. When the circular plate rotates on the side of the positioning frame, the threaded rod fixed to the side of the circular plate can rotate synchronously within the positioning frame.

[0013] Preferably, the circular plate is hinged to the movable block, the side of the movable block is fixedly connected to one end of the spring, and the other end of the spring is fixedly installed on the outer wall of the circular plate. When the movable block rotates clockwise with the circular plate and is pressed against it, the spring can be squeezed.

[0014] Preferably, a rotating rod is fixedly installed on the side of the circular plate. The rotating rod passes through the fixed ring and is rotatably connected to the fixed ring. When the rotating rod rotates, the circular plate fixed to the surface of the rotating rod can rotate synchronously within the fixed ring.

[0015] Preferably, the inner wall of the fixed ring is fixedly connected to one end of the second spring, the other end of the second spring is fixedly installed on the front of the ring, and a triangular block is fixedly installed on the inner wall of the ring. When the ring is no longer under tension, it will spring up from the fixed ring under the action of the second spring.

[0016] Preferably, the driven component includes a pull rod that passes through a fixed ring. A support block is fixedly installed on the side of the pull rod. The pull rod is rotatably connected to the front of the ring. A transverse hole is provided on the front of the fixed ring. When the support block on the side of the pull rod and the transverse hole are staggered, the movement of the pull rod and the ring can be restricted.

[0017] Compared with the prior art, the present invention provides an automotive seat frame mounting and positioning mechanism, which has the following advantages:

[0018] 1. The car seat frame installation and positioning mechanism is equipped with a control component. When the rotating rod is turned clockwise within the fixing ring, the rotating rod drives the circular plate and threaded rod to rotate within the positioning frame. The pressure plate moves towards the inner side of the positioning frame to fix the seat frame. When the circular plate rotates, the movable block will rotate clockwise synchronously and fold under the support of spring one when it is pressed. When the rotating rod is turned counterclockwise, the movable block hinged to the surface of the circular plate will be locked into the gap between the two sets of triangular blocks under the support of spring one, preventing the circular plate from rotating. This restricts the counterclockwise rotation of the rotating rod and the circular plate, preventing the pressure plate from shifting due to accidental reversal of the rotating rod when fixing the car seat frame.

[0019] 2. The car seat frame installation and positioning mechanism is equipped with a driven component. When the movable block moves out of the triangular block, the rotating rod can reverse. Therefore, when the support block fixed on the surface of the tie rod and the transverse hole form an interlocking shape, the ring connected to the surface of the tie rod cannot move, and the movable block and the triangular block cannot be separated, thereby achieving the purpose of secondary protection for the car seat frame after installation.

[0025] like Figures 1-4As shown, this utility model provides a technical solution: a car seat frame installation and positioning mechanism, including a positioning plate 1, a positioning frame 2 is bolted to the top of the positioning plate 1, a threaded rod 3 is provided inside the positioning frame 2, the threaded rod 3 passes through the positioning frame 2 and is rotatably connected to the positioning frame 2, the threaded rod 3 passes through the pressure plate 4 and is threadedly connected to the pressure plate 4, a control component 5 and a driven component 6 are provided on the side of the positioning frame 2, the control component 5 includes: a support rod 51, a circular plate 52, a movable block 53, a first spring 54, a rotating rod 55, a fixing ring 56, a second spring 57, a circular ring 58 and a triangular block 59. When the rotating rod 55 is rotated counterclockwise, the movable block 53 hinged to the surface of the circular plate 52 will be jammed into the gap between the two sets of triangular blocks 59 under the support of the first spring 54, so that the circular plate 52 cannot rotate. This restricts the counterclockwise rotation of the rotating rod 55 and the circular plate 52, and avoids the situation where the pressure plate 4 is displaced due to accidental reversal of the rotating rod 55 when fixing the car seat frame.

[0026] Support rod 51 is fixedly installed on the side of pressure plate 4. Support rod 51 passes through positioning frame 2 and is slidably connected to positioning frame 2. When pressure plate 4 moves, support rod 51 can support the movement of pressure plate 4. The side of threaded rod 3 is fixedly connected to circular plate 52. The side of circular plate 52 is rotatably connected to the side of positioning frame 2. When circular plate 52 rotates on the side of positioning frame 2, threaded rod 3 fixed to the side of circular plate 52 can rotate synchronously within positioning frame 2. Circular plate 52 is hinged to movable block 53. The side of movable block 53 is fixedly connected to one end of spring 54. The other end of spring 54 is fixedly installed on the outer wall of circular plate 52. When movable block 53 rotates clockwise with circular plate 52 and is pressed against, spring 54 can be squeezed. A rotating rod 55 is fixedly mounted on the side of the circular plate 52. The rotating rod 55 passes through the fixed ring 56 and is rotatably connected to the fixed ring 56. When the rotating rod 55 rotates, the circular plate 52 fixed to the surface of the rotating rod 55 can rotate synchronously within the fixed ring 56. The inner wall of the fixed ring 56 is fixedly connected to one end of the second spring 57. The other end of the second spring 57 is fixedly mounted on the front of the circular ring 58. A triangular block 59 is fixedly mounted on the inner wall of the circular ring 58. When the circular ring 58 is no longer under tension, it will spring up from within the fixed ring 56 under the action of the second spring 57. The driven component 6 includes a pull rod 61, which passes through the fixed ring 56. A support block 62 is fixedly mounted on the side of the pull rod 61. The pull rod 61 is rotatably connected to the front of the circular ring 58. A transverse hole 63 is opened on the front of the fixed ring 56. When the support block 62 on the side of the pull rod 61 and the transverse hole 63 are staggered, the movement of the pull rod 61 and the circular ring 58 can be restricted.

[0027] In this invention, during use, the car seat frame is placed into the two sets of positioning frames 2, and made to fit against the inner side of the positioning frames 2. After fitting, the rotating rod 55 is turned on the side of the positioning frame 2. When the rotating rod 55 rotates, the circular plate 52 fixed to the surface of the rotating rod 55 can rotate synchronously. When the circular plate 52 rotates clockwise, the movable block 53 hinged to the surface of the circular plate 52 will abut against the surface of the triangular block 59. The movable block 53 can be folded when it is abutted. During the clockwise rotation of the circular plate 52, the threaded rod 3 fixed to the surface of the circular plate 52 can rotate synchronously. When the threaded rod 3 rotates, the pressure plate 4 moves towards the car seat frame. The support rod 51 fixed to the surface of the pressure plate 4 moves within the positioning frame 2. The support rod 51 can support the movement of the pressure plate 4. After it is fixed, the rotating rod 55 is no longer rotated. When it is necessary to release the fixation of the car seat frame, the fixing ring 5 When the pull rod 61 rotates, the support block 62 fixed on the surface of the pull rod 61 will become parallel to the transverse hole 63. After becoming parallel, the pull rod 61 is pulled, and the ring 58 connected to the surface of the pull rod 61 moves synchronously, causing the triangular block 59 to disengage from the movable block 53. After disengagement, the pulling force is maintained, and the rotating rod 55 is rotated counterclockwise. Then the pressure plate 4 will no longer fix the car seat frame. When the pull rod 61 no longer pulls the ring 58, the ring 58 can bounce up under the action of the second spring 57. After bouncing up, when the rotating rod 55 is rotated counterclockwise, the movable block 53 hinged on the surface of the circular plate 52 will be stuck in the gap between the two sets of triangular blocks 59 under the support of the first spring 54, so that the circular plate 52 cannot rotate. This restricts the counterclockwise rotation of the rotating rod 55 and the circular plate 52, and avoids the situation where the pressure plate 4 is displaced due to accidental reversal of the rotating rod 55 when fixing the car seat frame.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
