[0015] Beneficial effects
[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:
[0017] I. This utility model, through the cooperative structure of limiting posts and limiting grooves, can provide precise guidance and stable positioning for the bracket, preventing the bracket from shifting or shaking during the operation of the tooling and ensuring the stability of the overall structure. The motor can synchronously drive the transmission wheel and the screw to rotate. The screw, through threaded transmission, drives the telescopic post to move horizontally, thereby flexibly adjusting the horizontal position of the fixed frame to adapt to different lengths of automotive interior armrests. The auxiliary frame, which is movably connected to the top and bottom of the fixed frame, can be finely adjusted in angle according to the actual shape of the armrest, providing initial support and positioning for the armrest, laying a solid foundation for subsequent precise clamping and posture adjustment, and effectively solving the problem of poor adaptability of traditional tooling to armrests of different sizes and shapes.
[0018] II. By setting up a second transmission wheel, the transmission groove provides an independent and orderly installation and operation space for the second transmission wheel, the transmission belt, and the rollers, avoiding mutual interference between transmission components and optimizing the internal layout of the tooling. The first pair of bearings ensures the coaxiality of the second transmission wheel, ensuring that the second transmission wheel does not deviate when rotating, thus improving the accuracy of power transmission. The transmission belt connects the power of the first and second transmission wheels, while the rollers on the front and rear sides of the left side of the transmission groove contact and roll with the bend of the transmission belt, which can significantly reduce the frictional resistance of the transmission belt during operation, reduce power loss, extend the service life of the transmission components, and improve power transmission efficiency, ensuring stable drive for subsequent height adjustment or flipping functions.
[0019] Third, this utility model, by setting a toothed column, allows the tooth groove at the top of the transmission wheel two to engage with the toothed column, providing a switchable channel for the transmission of power between the transmission wheel two and the toothed column. The bearing two supports and limits the toothed column, preventing it from shifting during rotation or movement and ensuring the meshing accuracy between the tooth groove and the toothed column. The electric telescopic rod one moves up and down through the drive connecting frame, which can drive the toothed column to adjust its position in the vertical direction, thereby controlling the engagement or disengagement of the top / bottom protrusions of the toothed column with subsequent components (gear groove two / threaded cylinder groove one), realizing flexible switching of the power transmission path, providing a core control basis for the independent operation of the tooling height adjustment and flipping functions, and solving the problem of traditional tooling having a single function and being unable to flexibly switch operating modes.

[0029] The present invention will be further described below with reference to the embodiments.
[0030] See attached document Figure 1-6 A type of automotive interior armrest assembly includes a base 1, a bracket 2, a limiting post 3, and a limiting groove 4. The bracket 2 is located on the top left side of the base 1, the limiting post 3 is fixedly connected to the top left side of the base 1, and the limiting groove 4 is opened on both sides of the bottom of the bracket 2. A drive mechanism 5 is fixedly connected to the top of the inner wall of the bracket 2. The drive mechanism 5 includes a motor 51, which is fixedly connected to the top of the inner wall of the bracket 2. A transmission wheel 52 is fixedly connected to the left side of the motor 51, and a screw 53 is fixedly connected to the right side of the motor 51. A telescopic post 54 is sleeved on the surface of the screw 53, and a fixing frame 55 is fixedly connected to the right side of the telescopic post 54. An auxiliary frame 56 is movably connected to both the top and bottom of the fixing frame 55.
[0031] Furthermore, a transmission groove 6 located at the bottom of the motor 51 is provided on the top of the inner wall of the bracket 2. A bearing 7 is fixedly connected to the inner wall of the transmission groove 6. A transmission wheel 8 is fixedly connected to the inner wall of the bearing 7. A transmission belt 9 is sleeved on the surface of the transmission wheel 8. The other end of the transmission belt 9 is sleeved on the surface of the transmission wheel 52. Rollers 10 that cooperate with the transmission belt 9 are movably connected to the front and rear sides of the left side of the transmission groove 6.
[0032] Through the above scheme, the transmission groove 6 provides an independent and orderly installation and operation space for the second transmission wheel 8, the transmission belt 9, and the rollers 10, avoiding mutual interference between transmission components and optimizing the internal layout of the tooling; the bearing 7 ensures the coaxiality of the second transmission wheel 8, ensuring that the second transmission wheel 8 does not deviate when rotating, and improving the accuracy of power transmission; the transmission belt 9 realizes the power connection between the first transmission wheel 52 and the second transmission wheel 8, while the rollers 10 on the front and rear sides of the left side of the transmission groove 6 contact and roll with the bend of the transmission belt 9, which can greatly reduce the frictional resistance of the transmission belt 9 during operation, reduce power loss, extend the service life of the transmission components, and improve the power transmission efficiency, ensuring the stable drive of subsequent height adjustment or flipping functions.
[0033] Furthermore, the top of the transmission wheel 8 is provided with a toothed groove 11, the inner wall of the toothed groove 11 is movably connected with a toothed column 12, the bottom of the toothed column 12 is fixedly connected with a bearing 13, the surface of the bearing 13 is fixedly connected with a connecting frame 14, the bottom of the left side of the inner wall of the transmission groove 6 is fixedly connected with an electric telescopic rod 15, the piston end of the electric telescopic rod 15 is fixedly connected to one side of the bottom of the connecting frame 14, and the top and bottom of the toothed column 12 are both fixedly connected with protrusions 16.
[0034] Through the above scheme, the tooth groove 11 on the top of the transmission wheel 2 8 engages with the tooth column 12, providing a switchable channel for the transmission of power between the transmission wheel 2 8 and the tooth column 12. The bearing 2 13 supports and limits the tooth column 12, preventing the tooth column 12 from shifting during rotation or movement, and ensuring the meshing accuracy of the tooth groove 11 and the tooth column 12. The electric telescopic rod 15 moves up and down through the drive connecting frame 14, which can drive the tooth column 12 to adjust its position in the vertical direction, thereby controlling the engagement or disengagement of the top / bottom protrusion 16 of the tooth column 12 with the groove 28 of the gear 27 / groove 20 of the threaded cylinder 18 of the subsequent component, realizing the flexible switching of the power transmission path, providing the core control basis for the independent operation of the tooling height adjustment and flipping function, and solving the problem of the traditional tooling having a single function and being unable to flexibly switch the operation mode.
[0035] Furthermore, a bearing 17 is fixedly connected to the bottom of the inner wall of the transmission groove 6, and a threaded cylinder 18 is fixedly connected to the inner wall of the bearing 17. A screw 19 located inside the limiting post 3 and the limiting groove 4 is fixedly connected to the top of the base 1. The screw 19 is threadedly connected to the inner wall of the threaded cylinder 18. A groove 20 that cooperates with the protrusion 16 is opened on the top of the threaded cylinder 18. Movable grooves 21 are opened on both sides of the inner wall of the telescopic post 54.
[0036] Through the above scheme, bearing 17 provides stable support for threaded cylinder 18, ensuring that threaded cylinder 18 maintains coaxiality when rotating, and avoiding height adjustment jamming caused by threaded cylinder 18 offset; threaded cylinder 18 and screw 19 on base 1 are threadedly engaged. When the bottom protrusion 16 of toothed column 12 engages with the top groove 20 of threaded cylinder 18, toothed column 12 can drive threaded cylinder 18 to rotate, and drive bracket 2 to vertically lift and lower along screw 19 through threaded transmission, realizing height adjustment in the fixed state of workpiece without disassembly and re-clamping, solving the problem of cumbersome height adjustment in the prior art; movable grooves 21 on both sides of the inner wall of telescopic column 54 provide space for the subsequent installation and movement of electric telescopic rod 22, inclined block 23 and toothed plate 24, ensuring the realization of the precise clamping function of telescopic column 54.
[0037] Furthermore, an electric telescopic rod 22 is fixedly connected to the right side of the inner wall of the movable groove 21. An inclined block 23 is fixedly connected to the piston end of the electric telescopic rod 22. A toothed plate 24 that cooperates with the inclined block 23 is movably connected to the side of the inner wall of the movable groove 21 that is close to each other. The toothed plate 24 is threadedly connected to the surface of the screw 53. Tension springs 25 are fixedly connected to both sides of the toothed plate 24 on the side away from the screw 53. The other end of the tension spring 25 is fixedly connected to the inner wall of the telescopic column 54.
[0038] Through the above scheme, the electric telescopic rod 22 drives the inclined block 23 to move. The inclined block 23 pushes the toothed plate 24 towards the screw 53 through the inclined plane thrust and engages with it. At this time, the motor 51 drives the screw 53 to rotate, which can drive the toothed plate 24 to move left and right through the threaded transmission, thereby driving the telescopic column 54 to accurately adjust the horizontal position, realizing the precise clamping or loosening of the handrail, avoiding workpiece damage caused by uneven manual clamping force; the tension spring 25 on the side of the toothed plate 24 away from the screw 53 can pull the toothed plate 24 to reset when the electric telescopic rod 22 is retracted, so that the toothed plate 24 is separated from the screw 53, releasing the driving constraint of the screw 53 on the telescopic column 54, realizing the flexible switching between the driven and free movement states of the telescopic column 54; this structure realizes automated precise clamping through mechanical transmission, improves clamping efficiency and stability, and reduces the intensity of manual operation.
[0039] Furthermore, a bearing 26 is fixedly connected to the top of the inner wall of the transmission groove 6, a gear 27 is fixedly connected to the outer ring of the bearing 26, a groove 28 is provided at the bottom of the gear 27, a fixing ring 29 is fixedly connected to the top of the right side of the bracket 2, a bearing 30 is fixedly connected to the inner wall of the fixing ring 29, a toothed ring 31 is fixedly connected to the inner ring of the bearing 30, and the bottom of the left side of the toothed ring 31 is fixedly connected to one side of the gear 27.
[0040] Through the above scheme, bearing 26 provides stable support for gear 27, ensuring that gear 27 does not deviate when rotating and guaranteeing the stability of power transmission. The groove 28 at the bottom of gear 27 can precisely cooperate with the protrusion 16 on the top of gear column 12. When the protrusion 16 on the top of gear column 12 is inserted into groove 28, gear column 12 can drive gear 27 to rotate, thereby driving the gear ring 31 fixed to gear 27 to rotate synchronously. The fixed ring 29 cooperates with bearing 30 to form a double support and limit for gear ring 31. The inner ring of bearing 30 is connected to gear ring 31, and the outer ring is connected to fixed ring 29, ensuring that gear ring 31 maintains coaxiality when rotating. This provides a stable power transmission path for subsequently driving telescopic column 54 and workpiece flipping, and provides a structural basis for solving the defect of "workpiece cannot be flipped after being fixed".
[0041] Furthermore, a limiting block 32 is fixedly connected to the right side of the inner wall of the toothed ring 31, and sliding grooves 33 are provided on both sides of the telescopic column 54, with the limiting block 32 movably connected to the inner wall of the sliding groove 33.
[0042] With the above scheme, the limiting block 32 on the inner wall of the toothed ring 31 is movably connected to the sliding groove 33 on both sides of the telescopic column 54. When the toothed ring 31 rotates, the limiting block 32 can slide along the sliding groove 33 and drive the telescopic column 54 to rotate synchronously, realizing the flipping of the workpiece on the fixed frame 55. The sliding groove 33 plays a guiding and limiting role for the limiting block 32, preventing the limiting block 32 from disengaging or deviating when it drives the telescopic column 54 to rotate, ensuring a smooth and wobbly flipping process. With this structure, the workpiece can be flipped in multiple directions while in a fixed state without disassembly and re-clamping, effectively improving the efficiency of inspection or processing, while avoiding damage problems such as scratches and deformation of the workpiece caused by repeated clamping.
[0043] Furthermore, a fixing post 34 is fixedly connected to the right side of both the fixed frame 55 and the auxiliary frame 56, and a rubber pad 35 is fixedly connected to the right side of the fixing post 34. A servo motor 36 is fixedly connected to the inner wall of the auxiliary frame 56 near the fixed frame 55, and the output end of the servo motor 36 is fixedly connected to the inner wall of the fixed frame 55.
[0044] Through the above scheme, the fixing post 34 on the right side of the fixing frame 55 and the auxiliary frame 56 can directly contact the handrail, forming multi-point support and improving the stability of the handrail after fixing. The rubber pad 35 on the right side of the fixing post 34 can increase the friction with the surface of the handrail, further strengthening the clamping effect, while avoiding surface scratches, pressure marks and other damage caused by the metal fixing post 34 directly contacting the handrail, thus protecting the appearance quality of the workpiece. The servo motor 36 on the inner wall of the auxiliary frame 56 can drive the auxiliary frame 56 to rotate around the fixing frame 55, flexibly adjusting the angle of the auxiliary frame 56, so that the auxiliary frame 56 can adapt to different curvatures and shapes of automotive interior handrails, such as curved handrails and irregular handrails, greatly improving the adaptability of the tooling to diverse workpieces and meeting the processing or inspection needs of handrails of different specifications.
[0045] Working principle: The limiting post 3 and the limiting groove 4 can stably limit the bracket 2, preventing the bracket 2 from shifting during the tooling operation, and providing a structural stability basis for subsequent operations. In actual use, the motor 51 is started first. The output shaft of the motor 51 synchronously drives the left transmission wheel 52 and the right screw 53 to rotate. When the transmission wheel 52 rotates, it drives the transmission wheel 8 in the transmission groove 6 to rotate through the transmission belt 9. The transmission groove 6 not only provides installation and movement space for the transmission wheel 8, the transmission belt 9 and the roller 10, but also fixes the bearing 7. The bearing 7 can support and limit the transmission wheel 8, ensuring that the transmission wheel 8 maintains coaxiality when rotating and avoiding power transmission deviation. At the same time, the roller 10 on the front and rear sides of the left side of the transmission groove 6 contacts the bend of the transmission belt 9 and rotates synchronously, which can effectively reduce the frictional resistance of the transmission belt 9 during rotation and reduce power loss. When the transmission wheel 8 rotates, it drives the toothed groove 11 on its top to rotate synchronously. The toothed groove 11 and the toothed column 12 form a movable mesh to transmit power. At this time, the electric telescopic rod 15 is activated. The piston end of the electric telescopic rod 15 drives the connecting frame 14 to move downward. The connecting frame 14 simultaneously drives the bearing 13 and the gear column 12 fixed to it to move downward. The bearing 13 can support and limit the gear column 12, ensuring the stability of the movement and rotation of the gear column 12. When the protrusion 16 at the bottom of the gear column 12 precisely engages with the groove 20 at the top of the threaded cylinder 18, the gear column 12 can drive the threaded cylinder 18 to rotate. The bearing 17 provides fixed support for the threaded cylinder 18, ensuring that the threaded cylinder 18 does not deviate when rotating. The threaded cylinder 18 is threadedly connected to the screw 19 at the top of the base 1. When the threaded cylinder 18 rotates, it will push the bracket 2 to move vertically upward along the screw 19 through the threaded transmission, thereby realizing the lifting of the workpiece height. By controlling the rotation direction of the motor 51, the threaded cylinder 18 can be driven to rotate in the opposite direction, thereby controlling the bracket 2 to descend, thus adapting to workpieces with different height requirements. After the height adjustment is completed, the electric telescopic rod 15 drives the connecting frame 14 to move upward, causing the protrusion 16 at the bottom of the gear column 12 to separate from the groove 20 of the threaded cylinder 18. At this time, the gear column 12 is in an idle state and no longer transmits power to the threaded cylinder 18. When it is necessary to flip the workpiece, the electric telescopic rod 15 continues to push the connecting frame 14 upward, so that the protrusion 16 at the top of the gear column 12 is inserted into the groove 28 at the bottom of the gear 27. At this time, the rotation of the gear column 12 can drive the gear 27 to rotate synchronously. The bearing 26 provides fixed support for the gear 27, ensuring the stable rotation of the gear 27. The gear 27 is fixedly connected to the bottom left side of the gear ring 31. When the gear 27 rotates, it will drive the gear ring 31 to rotate. The fixing ring 29 at the top right side of the bracket 2 provides support and limit for the gear ring 31 through the bearing 30. The inner ring of the bearing 30 is fixed to the gear ring 31, and the outer ring is fixed to the fixing ring 29, ensuring the coaxiality of the gear ring 31 when it rotates.The limiting block 32 on the right side of the inner wall of the toothed ring 31 is movably connected to the sliding grooves 33 on both sides of the telescopic column 54. When the toothed ring 31 rotates, it will drive the telescopic column 54 to rotate synchronously through the cooperation of the limiting block 32 and the sliding groove 33. The telescopic column 54 will then drive the fixed frame 55 and the fixed workpiece to rotate, realizing the workpiece flipping operation. Multiple surfaces of the workpiece can be inspected or operated without disassembling and re-clamping the workpiece. After the flipping is completed, the electric telescopic rod 15 is controlled to drive the connecting frame 14 to move downward, so that the protrusion 16 on the top of the toothed column 12 separates from the groove 28 of the gear 27, and the flipping power transmission stops. After the workpiece height and flipping posture are adjusted, the electric telescopic rod 22 in the movable grooves 21 on both sides of the inner wall of the telescopic column 54 is activated. The piston end of the electric telescopic rod 22 pushes the inclined block 23 to move. The inclined block 23 drives the toothed plate 24 to move towards the screw 53 through the inclined surface thrust until the toothed plate 24 and the surface of the screw 53 form a threaded engagement. At this time, motor 51 drives screw 53 to rotate, which pushes toothed plate 24 to move to the right through threaded transmission. Toothed plate 24 simultaneously drives telescopic column 54 to move to the right, so that fixed column 34 on the right side of fixed frame 55 and auxiliary frame 56 moves closer to workpiece. Rubber pad 35 on the right side of fixed column 34 contacts and abuts against workpiece surface, achieving stable clamping of workpiece. Rubber pad 35 can prevent fixed column 34 from directly contacting workpiece and causing surface damage. At the same time, servo motor 36 on the inner wall of auxiliary frame 56 near fixed frame 55 is activated. The output end of servo motor 36 is fixedly connected to the inner wall of fixed frame 55. When servo motor 36 is running, it can drive auxiliary frame 56 to rotate around fixed frame 55, thereby adjusting the angle of auxiliary frame 56 to adapt to different shapes and specifications of automotive interior armrests. By controlling the rotation direction of motor 51, toothed plate 24 and telescopic column 54 can be driven to move to the left to realize workpiece release operation.
