Description

Technical Field

[0001] This invention relates to the field of running-in technology for automotive seat slide rails, specifically to a running-in device and running-in method for automotive seat slide rails. Background Technology

[0002] Car seat rails are an important component of a car, primarily used for adjusting the seat's fore-and-aft position. The structure of a car seat rail is as follows: Figures 1-2 As shown, it mainly includes an outer rail 102 and an inner rail 101. The outer rail 102 is a U-shaped component, and the inner rail 101 is located inside the outer rail 102. An electric slide rail screw 103 is provided between the outer rail 102 and the inner rail 101. The two ends of the electric slide rail screw 103 are provided with brackets that contact the outer rail 102.

[0003] There are specific standards for the sliding force between the outer and inner rails in a vehicle. After machining, the sliding force between the outer and inner rails is usually insufficient for vehicle operation; they need to undergo a certain number of break-in cycles to meet the requirements. This break-in process is typically performed on a specialized break-in machine. In existing technology, the outer rail is usually fixed to the worktable of the break-in machine, and a drive component is used to drive the inner rail to slide back and forth relative to the outer rail, thereby achieving friction between them.

[0004] For example, Chinese invention patent application CN201711001996.8, entitled "A Break-in Machine and Control Method for Car Seat Rails," discloses a break-in machine. This machine includes a frame, on which are mounted a crank drive mechanism and a slider mechanism. The crank drive mechanism includes a cam connected to a vertically oriented rotating shaft. The slider mechanism includes a slide body, the bottom of which slides against the frame. The slide body has a rail positioning component for positioning the outer rail of the seat rail. The end of the slide body is connected to the cam via a connecting rod, allowing the slide body to reciprocate relative to the frame under the rotation of the cam. This break-in machine achieves the break-in effect by reciprocating the outer rail. However, this machine is only suitable for break-in manual rail structures and is not applicable to seat rails equipped with electric rail screws. This inapplicability is multifaceted. First, during the break-in process, the supports at both ends of the electric slide rail's lead screw will rub against the outer rail, damaging the paint layer on the outer rail. Second, for manual slide rail structures, the break-in process between the outer and inner rails requires unlocking them. Without unlocking, they are completely fixed together, making sliding break-in impossible. The aforementioned device does not mention a structure for unlocking the inner and outer rails, meaning it only applies to electric slide rail structures and cannot be applied to manual slide rail structures. Third, in some cases, the inner and outer rails do not fit tightly during the break-in process. If only an axial pushing and pulling force is applied to the inner and outer rails, a good break-in effect may not be achieved. This is because, in actual use, the slide rail has a seat, meaning the inner and outer rails bear a certain amount of pressure under normal use. Applying only an axial pushing and pulling force during the break-in process does not match the normal operating condition of the inner and outer rails, resulting in a poor break-in effect.

[0025] The advantages of this application are: 1. The car seat slide rail break-in device of this application has a simple structure and is suitable for various specifications of seat slide rails. This application fixes the inner rail and the lead screw, drives the outer rail to reciprocate relative to the inner rail. Before break-in, the lead screw is lifted by the lead screw lifting structure to remove the bracket on the lead screw from the outer rail, so as to avoid damaging the paint of the outer rail during break-in. During break-in, the load structure applies downward pressure to the inner rail, forcing the inner rail and the outer rail to make close contact, improving the break-in effect. The entire break-in device has good adaptability, extremely high break-in efficiency, and is simple to operate and easy to use. 2. The outer rail clamping structure of this application can easily and quickly clamp the outer rail. The outer rail is placed between the fixed block and the movable block. It can be adapted to clamp the outer rail of various types of slide rails. It is simple to operate, has good adaptability, and its structure is simple and extremely convenient to use. 3. The break-in drive structure of this application includes a flywheel and a connecting rod. The reciprocating linear motion of the outer rail can be realized through the rotational motion of the flywheel, which greatly improves the break-in efficiency, improves the break-in effect, and greatly shortens the break-in time. 4. This application sets multiple pin holes on the flywheel, each corresponding to a different break-in stroke. This can adapt to the break-in requirements of different specifications of slide rails. In actual application, it is only necessary to change the corresponding fixing pin hole of the connecting rod to change the stroke of the reciprocating linear motion of the other end of the connecting rod to adapt to different break-in requirements. 5. The inner rail clamping structure of this application uses an inner rail chuck to clamp the inner rail. The structure is simple and easy to operate. It can clamp the inner rail in the axial direction very well. At the same time, the inner rail chuck is an L-shaped structure, which can easily restrict and fix the inner rail. 6. The lead screw lifting structure of this application is simple. The lifting rod is driven axially by the axial drive structure to clamp and fix the end of the lead screw. The lifting rod is lifted vertically by the vertical drive structure, so that the lead screw moves vertically and gets off the outer rail, thus avoiding damage to the paint on the outer rail of the lead screw bracket during the break-in process. 7. This application uses a vertical drive structure to drive the lifting rod and connecting screw to move vertically, relative to the inner rail. The vertical drive structure is driven by a lifting cylinder. The structure is simple, easy to operate and use, and can be fully automated, which greatly improves the efficiency of slide rail break-in. 8. This application sets a vertical guide rail on the support plate, and uses the guide rail to guide the vertical movement of the connecting plate, ensuring that the connecting plate can only move vertically, making the lifting movement of the lead screw smoother, the lifting of the lead screw more convenient and accurate, and the overall operation simpler. 9. This application provides a limiting block on the support plate to limit the vertical movement of the connecting plate, thereby preventing damage to the lead screw and inner rail structure that may result from excessive upward movement of the connecting plate. 10. The axial drive structure of this application drives the lifting rod to move axially using a servo motor. The servo motor can adjust the length of the lifting rod moving axially according to the slide rail structure to be broken in, so as to adapt to the lifting of slide rail screws of different specifications and greatly improve the applicability of the whole device. 11. This application provides a guide structure on the support plate to guide the axial movement of the lifting rod, ensuring that the lifting rod can accurately enter the slide rail to clamp and position the lead screw. The guide structure of this application is simple and easy to operate. The combination of the guide rod and the guide sleeve can effectively limit the non-axial movement of the lifting rod. 12. The load structure of this application is very simple. The load plate is driven to move downward by the load cylinder, so that the load plate can apply downward pressure to the inner rail, forcing the inner rail to fit tightly against the outer rail, simulating the real use scenario of the slide rail, and the running-in effect is better. 13. The unlocking structure of this application can be applied to the unlocking of manual slide rail structures. By driving the unlocking head to move down and insert it into the corresponding key hole, the unlocking effect can be achieved. The overall structure is simple and easy to operate. 14. This application also provides a running-in method for automotive seat slide rails. The running-in method of this application includes clamping the outer rail, clamping the inner rail, clamping and lifting the lead screw, applying load to the inner rail, and driving the outer rail to reciprocate for running-in. The overall operation process is reasonably designed, the running-in efficiency is extremely high, and the operation is simple. 15. The method of clamping the outer rail in this application is very simple. The outer rail clamping structure can be adapted to slide rails of different lengths and specifications, and has excellent versatility. 16. The method of clamping the inner rail in this application is very simple. By moving the support plate on one side along the axis, the inner rail in the slide rail can be well clamped by the inner rail chuck. The operation is simple and convenient. 17. The screw lifting method of this application is very simple to operate. The screw can be clamped in the axial direction by driving the lifting rod in the axial direction. Then, the screw can be lifted vertically to drive the screw to move vertically and make the bracket on the screw detach from the outer rail, thus avoiding damage to the paint on the outer rail of the screw bracket during the break-in process. 18. The method of adjusting the load on the inner rail in this application is simple. By applying vertical downward pressure to the inner rail through the load plate, the inner rail can be made to fit tightly against the outer rail, simulating the real use of the slide rail and improving the running-in effect. 19. The method of driving the reciprocating motion of the outer rail in this application is very simple. The rotational motion of the flywheel is converted into the axial reciprocating motion of the outer rail, which has extremely high running-in efficiency and short running-in time, and greatly improves the efficiency of slide rail processing.

[0026] The car seat slide rail break-in device of this application has a simple structure and is easy to use. It can greatly improve the efficiency of slide rail break-in, avoid the problem of damage to the paint on the outer rail during the slide rail break-in process, has a short break-in time, and a good break-in effect, and has great promotional value.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] This application relates to a running-in device for automotive seat slide rails. This device is used for running-in automotive seat slide rails. During the running-in process, the inner rail and lead screw are fixed, driving the outer rail to reciprocate axially to achieve the running-in effect. During the running-in process, the lead screw is clamped, fixed, and lifted, causing the support on the lead screw to disengage from the outer rail, preventing wear on the paint layer of the outer rail during the running-in process. Simultaneously, to simulate real-world use of seat slide rails, this application applies a downward vertical load to the inner rail during the running-in process, ensuring the inner rail fits tightly against the outer rail. This makes the running-in process of the inner and outer rails more closely resemble real-world use, resulting in better running-in performance and higher wear efficiency.

[0033] Specifically, such as Figures 3-8As shown, this application discloses a car seat slide rail break-in device, including a support 1, an outer rail clamping structure, a break-in drive structure, two sets of inner rail clamping structures, two sets of screw lifting structures, a load structure, and an unlocking structure. The support 1 is the bearing base of the entire break-in device. The break-in device of this application mainly includes two parts: one located below as the bearing base for the outer rail of the slide rail, and the other located above as the clamping and fixing base for the inner rail of the slide rail and the screw. The support 1 is located above as the clamping and fixing base for the inner rail and the screw. The outer rail clamping structure is located below the support 1 and is used to support the slide rail and clamp and fix the outer rail in the slide rail. The break-in drive structure is connected to the outer rail clamping structure to drive the outer rail clamping structure and the clamped outer rail to reciprocate axially; two sets of inner rail clamping structures are placed on both sides of the support 1 to clamp the inner rail in the slide rail axially; two sets of screw lifting structures are placed on both sides of the support 1 to clamp the screw in the slide rail axially and lift it vertically so that the bracket on the screw is disengaged from the outer rail before break-in; the load structure is set on the support 1 to apply a vertically downward load to the inner rail so that the inner rail and the outer rail fit tightly together; the unlocking structure is set on the support 1 to extend vertically into the locking hole on the inner rail to unlock the inner rail and the outer rail.

[0034] The outer rail clamping structure is used to support and clamp the outer rail in the fixed slide rail, clamping both ends of the outer rail along its axial direction (in this application, axial direction refers to the length direction of the slide rail). The running-in drive structure is connected to the outer rail clamping structure, driving the outer rail clamping structure and the outer rail clamped by the outer rail clamping structure to reciprocate along the axial direction to achieve the running-in effect. The inner rail clamping structure is used to clamp the inner rail from both ends of its axial direction. The inner rail clamping structure and the outer rail clamping structure are not directly connected; the inner and outer rails are clamped independently. The screw lifting structure corresponds to the inner rail clamping structure. The lead screw is clamped at both ends along its axial direction and lifted vertically, causing the bracket on the lead screw to detach from the outer rail, thus preventing damage to the paint layer of the outer rail during the break-in process. The load structure applies pressure vertically to the inner rail, forcing the inner rail to make close contact with the outer rail, simulating the actual use of the slide rail. The unlocking structure is mainly considered for the break-in of manual slide rail structures, which require the inner and outer rails to be unlocked before the outer rail can be driven to reciprocate axially relative to the inner rail. Therefore, the break-in device of this application with the unlocking structure can be applied to the break-in of manual slide rails, making it more applicable.

[0035] Specifically, the running-in device of this application is used in accordance with the following steps: S1. Place the slide rail to be broken in onto the outer rail clamping structure, and the outer rail clamping structure clamps the outer rail of the slide rail. S2. The two sets of inner rail clamping structures move towards each other to axially clamp the inner rails in the slide rail. S3. The lead screw lifting structure axially clamps the lead screw in the slide rail. After clamping and fixing, it lifts the lead screw vertically to disengage the bracket on the lead screw from the outer rail. S4. The load structure applies a vertical downward load to the inner rail to ensure close contact between the inner rail and the outer rail. If it involves a manual slide rail structure, then an unlocking mechanism is needed to unlock the slide rail. S5. The running-in drive structure drives the outer rail to reciprocate along the axial direction until the running-in operation is completed.

[0036] In some embodiments of this application, the outer rail clamping structure and the break-in drive structure described above have been optimized. Both the outer rail clamping structure and the break-in drive structure involve the outer rail, such as... Figure 4 As shown, the outer rail clamping structure of this embodiment includes a base 13, a fixed block 14, and a movable block 15. A track arranged along the axial direction is provided below the base 13. In fact, the track is set on the worktable. The track is arranged along the axial direction of the slide rail. The base 13 is slidably connected to the track. The fixed block 14 is fixed to one axial end of the base 13. The movable block 15 is connected to the base 13 and can be moved along the axial direction by a drive cylinder on the base 13.

[0037] When actually clamping the outer rail of the slide rail, the robot arm moves the slide rail and places it horizontally on the base 13 with the outer rail facing down and the inner rail facing up. One end of the outer rail of the slide rail is pressed against the fixed block 14 on one side of the base 13. The drive cylinder on the base 13 is driven to move the movable block axially towards the other end of the outer rail until it contacts the other end of the outer rail, clamping and fixing the outer rail between the fixed block 14 and the movable block 15.

[0038] like Figure 4 As shown, the break-in drive structure of this embodiment includes a flywheel 16 and a connecting rod 17. The flywheel 16 is a horizontal flywheel structure that can rotate around a vertical axis via a motor. The flywheel 16 is provided on one side of the base 13 in the axial direction, which can be either the fixed block 14 side or the movable block 15 side. One end of the connecting rod 17 is hinged to the base 13 and can rotate around a vertical axis, while the other end is hinged to the flywheel 16 and can rotate around a vertical axis.

[0039] One difference between the break-in device in this embodiment and the existing break-in device is that the existing break-in device has a stationary outer rail and a reciprocating inner rail relative to the outer rail, while in this embodiment, the flywheel 16 drives the base 13 to reciprocate through the connecting rod 17, that is, the outer rail reciprocates relative to the inner rail, while the inner rail is stationary.

[0040] During the actual break-in process, the flywheel 16 is driven to rotate around the vertical axis. The flywheel 16 drives one end of the connecting rod 17 to rotate. The other end of the connecting rod 17 is connected to the base 13, driving the base 13 and the outer rail fixed on the base 13 to reciprocate along the axial direction, thus achieving the break-in effect.

[0041] The rotational motion of flywheel 16 is transformed into the reciprocating motion of base 13, resulting in extremely high operating efficiency and a very short break-in time to achieve good break-in results.

[0042] To accommodate different specifications of slide rails, this embodiment has multiple pin holes on the flywheel 16 corresponding to different break-in strokes. The pin holes with different strokes are actually at different distances from the center of the upper surface of the flywheel 16. The smaller the distance from the center of the flywheel 16, the smaller the stroke; the larger the distance from the center of the flywheel 16, the larger the stroke. One end of the connecting rod 17 is detachably connected to the pin hole by a pin (the pin passes vertically through the end of the connecting rod 17 and is inserted into the pin hole).

[0043] When using it, select the appropriate pin hole according to the slide rail specifications, and then insert the end of the connecting rod 17 into the corresponding pin hole through the pin to complete the assembly.

[0044] In other embodiments of this application, the inner rail clamping structure described above is optimized. This embodiment provides two sets of inner rail clamping structures, arranged axially opposite to each other. The two sets of inner rail clamping structures work together to clamp the inner rail in the slide rail in the axial direction. Specifically, as... Figures 5-8 As shown, the inner rail clamping structure includes a support plate 2 and an inner rail clamp 11. The support plate 2 is connected to the support 1. At least one set of support plates 2 can be driven to move along the slide rail axis by a clamping cylinder installed on the support 1. The inner rail clamp 11 is an L-shaped plate structure fixed on the support plate 2.

[0045] The vertical part of the inner rail clamp 11 is fixed on the support plate 2, and its horizontal part is used to contact the inner rail. The lower end face of the horizontal part contacts the upper end face of the inner rail, which restricts the upward movement of the inner rail when adjusting the vertical position of the lifting rod 3, ensuring that the inner rail is fixed relative to the support plate 2 when adjusting the vertical position of the lifting rod 3.

[0046] In the two sets of inner rail clamping structures, one set of inner rail clamping structures can move along the axial direction, or both sets of inner rail clamping structures can move along the axial direction. This can adapt to the clamping operation of inner rails in slide rails of different specifications.

[0047] During actual clamping, once the outer rail in the slide rail is clamped, the clamping cylinder on the support 1 is driven to move the support plate 2, which is slidably connected to the support 1, axially toward the inner rail clamping structure on the other side until the inner rail clamps 11 on the support plates 2 on both sides abut against the two ends of the inner rail, thus completing the clamping of the inner rail.

[0048] In a further embodiment of this application, the above-mentioned lead screw lifting structure has been optimized, specifically, as follows: Figures 5-8 As shown, the lead screw lifting structure includes a lifting rod 3, which is a horizontal rod-shaped structure arranged along the slide rail axis. The lead screw lifting structure also includes an axial drive structure for driving the lifting rod 3 to move along the slide rail axis so that the end of the lifting rod 3 is inserted below the end of the lead screw, and a vertical drive structure for driving the lifting rod 3 to move vertically to lift the lead screw after the end of the lifting rod 3 is inserted below the end of the lead screw.

[0049] The lifting rod 3 is actually a structure installed on the support plate 2. It can move axially along with the support plate 2. The lifting rod 3 can move axially and vertically relative to the support plate 2. The two lifting rods 3 on both sides work together to clamp the lead screw axially and lift it vertically.

[0050] In actual operation, after the outer and inner rails of the slide rail are clamped and fixed, the lifting rod 3 is driven by the axial drive structure on both sides to insert into the slide rail, so that the lifting rod 3 abuts against the end of the electric lead screw. The lifting rods 3 on both sides work together to fix the lead screw. The vertical drive structure drives the lifting rod 3 to move vertically upward, so that the lead screw moves upward relative to the inner rail until the brackets at both ends of the lead screw disengage from the outer ring of the outer rail, thus completing the lead screw lifting process.

[0051] Specifically, such as Figure 7 As shown, the vertical drive structure of this embodiment includes a connecting plate 4 and a lifting cylinder 5. The connecting plate 4 is slidably connected to the support plate 2 in the vertical direction, and the connecting plate 4 is fixedly connected to the lifting rod 3 in the vertical direction. The lifting cylinder 5 is fixed on the support plate 2, and the telescopic end of the lifting cylinder 5 is fixedly connected to the connecting plate 4 for driving the connecting plate 4 to move vertically.

[0052] The lifting cylinder 5 is a vertical drive cylinder. The cylinder body of the lifting cylinder 5 is fixed on the support plate 2. The telescopic end of the lifting cylinder 5 is fixedly connected to the connecting plate 4. Under the action of the lifting cylinder 5, the connecting plate 4 can be driven to move vertically. The overall operation is very simple.

[0053] To facilitate the vertical movement of the connecting plate 4, this embodiment provides a vertically arranged guide rail 6 on the support plate 2. The connecting plate 4 is slidably connected to the guide rail 6, and a vertically arranged sliding groove is provided on the connecting plate 4, which engages with the guide rail 6. That is, during the process of the lifting cylinder 5 driving the connecting plate 4 to move vertically, the connecting plate 4 moves vertically along the guide rail 6, and the lifting rod 3 fixed on the connecting plate 4 can move vertically as well.

[0054] Furthermore, in this embodiment, a limiting block is provided on the support plate 2. When the connecting plate 4 moves vertically to its maximum position, the limiting block contacts the connecting plate 4 and restricts further upward movement of the limiting block. By using the limiting block to limit the vertical movement of the connecting plate 4, the problem of damage to the lead screw and inner rail structure caused by excessive upward movement of the connecting plate 4 is avoided.

[0055] In actual use, after the lead screw is completely clamped by the lifting rods 3 on both sides, the lifting cylinder 5 is driven. The lifting cylinder 5 drives the connecting plate 4 vertically, and the connecting plate 4 moves upward along the guide rail 6. The lifting rods 3 fixed on the connecting plate 4 clamp the end of the lead screw and move upward together with the connecting plate 4, lifting the lead screw and forcing the bracket on the lead screw to disengage from the outer rail, which facilitates the subsequent break-in operation.

[0056] like Figure 7 As shown, the axial drive structure of this embodiment includes a servo motor 8 fixed on the connecting plate 4, and one end of the lifting rod 3 is fixed to the servo motor 8 and driven by the servo motor 8 to move axially along the slide rail.

[0057] The servo motor 8 is fixed on the connecting plate 4, which means that the servo motor 8 can move vertically along with the connecting plate 4. The servo motor 8 can set and adjust the axial movement of the lifting rod 3, so as to adapt to the break-in operation of different specifications of slide rails.

[0058] The support plate 2 is equipped with a guide structure for the axial movement of the lifting rod 3 along the slide rail. For example... Figures 3-5 As shown, the guide structure includes a guide rod 9 and a guide sleeve 10. One end of the guide rod 9 is fixed to the connecting plate 4, and the other end is arranged along the axial direction of the parallel slide rail. The guide sleeve 10 is slidably connected to the guide rod 9 and is connected to the servo motor 8. The lifting rod 3 is fixedly connected to the guide sleeve 10 through the connecting rod 12. The lifting rod 3 is a rod-shaped structure with a tip that can abut against the end of the electric slide rail lead screw. The lifting rod 3 is detachably connected to the connecting rod 12.

[0059] The guiding structure formed by the guide rod 9 and the guide sleeve 10 can guide and limit the axial movement of the lifting rod 3, preventing the lifting rod 3 from moving in non-axial directions.

[0060] In actual operation, when the slide rail to be broken in is between the two sets of lead screw lifting structures, the servo motor 8 is driven. The servo motor 8 drives the guide sleeve 10 to move along the guide rod 9, and the connecting rod 12 follows the guide sleeve 10 to move, so that the tip of the lifting rod 3 is inserted into the set position (e.g., Figure 2 The lifting rods 3 on both sides (A and B in the middle) work together to clamp and fix the lead screw.

[0061] In actual operation, after the outer and inner rails of the slide rail are clamped and fixed, the inner rail clamp 11 moves to the upper end face of the inner rail and fits tightly against the inner rail; the servo motor 8 is driven, and the servo motor 8 drives the guide sleeve 10 to move along the guide rod 9. The connecting rod 12 moves with the guide sleeve 10, so that the tip of the lifting rod 3 is inserted into the set position. The lifting rods 3 on both sides work together to clamp and fix the lead screw; the lifting cylinder 5 is driven, and the lifting cylinder 5 drives the connecting plate 4 vertically. The connecting plate 4 moves upward along the guide rail 6. The lifting rod 3 fixed on the connecting plate 4 clamps the end of the lead screw and moves upward together with the connecting plate 4, lifting the lead screw and forcing the bracket on the lead screw to disengage from the outer rail.

[0062] In some embodiments of this application, the above-described load structure has been optimized, specifically, as follows: Figure 5 As shown, the load structure of this embodiment includes a load cylinder 18 and a load pressure plate 19. The load cylinder 18 is fixed on the support plate 2, and the output end of the load cylinder 18 is connected to the load pressure plate 19 to drive the load pressure plate 19 to move vertically.

[0063] The load cylinder 18 is fixed on the support plate 2. In other words, the running-in device in this embodiment includes two sets of load structures, which correspond one-to-one with the two sets of inner rail clamping structures. The two sets of load cylinders 18 extend and retract vertically to drive the load pressure plate 19 to apply vertical pressure to the inner rail, so that the inner rail and the outer rail are in close contact, achieving a good running-in effect and simulating the real slide rail usage scenario.

[0064] In actual operation, after the outer rail and inner rail of the slide rail are clamped and fixed, the load cylinder 18 drives the corresponding load pressure plate 19 to move down. The lower end of the load pressure plate 19 squeezes the inner rail, causing the inner rail to move down until it is completely and tightly fitted with the outer rail. The two sets of load pressure plates 19 work together to ensure that the inner rail will not tilt up on one side.

[0065] In a further embodiment of this application, the unlocking structure described above has been optimized, specifically, as follows: Figure 5 As shown, the unlocking structure includes an unlocking cylinder 20 and an unlocking head 21. The upper end of the unlocking cylinder 20 is slidably connected to the support 1 along the axial direction, and the lower end is connected to the unlocking head 21. The unlocking head 21 is a rod-shaped structure arranged vertically, whose lower end can be driven by the unlocking cylinder 20 to be inserted into the inner rail lock hole to unlock the inner rail and the outer rail.

[0066] The power output device in the unlocking structure, namely the unlocking cylinder 20, is slidably connected to the support 1. That is to say, the unlocking cylinder 20 can be adjusted according to the position of the lock hole on the slide rail so that the unlocking head 21 on the unlocking cylinder 20 is completely aligned with the lock hole below.

[0067] The unlocking mechanism is mainly used in manual slide rail structures. In actual operation, the position of the unlocking cylinder 20 is adjusted according to the position of the lock hole on the manual slide rail to be broken in, so that the unlocking head 21 is completely aligned with the position of the lock hole below. Then, the unlocking cylinder 20 drives the unlocking head 21 to move down until the unlocking head 21 is inserted into the lock hole, thus completing the unlocking.

[0068] During the actual running-in operation of the car seat slide rail running-in device of this application, the robotic arm moves the slide rail and places it horizontally on the base 13 with the outer rail facing down and the inner rail facing up. One end of the outer rail abuts against the fixed block 14 on one side of the base 13. The drive cylinder on the base 13 drives the movable block axially towards the other end of the outer rail until it contacts the other end of the outer rail, clamping and fixing the outer rail between the fixed block 14 and the movable block 15. The drive cylinder on the support 1 drives the support plate 2, which is slidably connected to the support 1, axially towards the inner rail on the other side. The clamping structure moves until the inner rail clamps 11 on the support plates 2 on both sides abut against the two ends of the inner rail, completing the clamping of the inner rail; the load cylinder 18 drives the corresponding load pressure plate 19 to move down, and the lower end of the load pressure plate 19 squeezes the inner rail, causing the inner rail to move down until it is completely and tightly fitted with the outer rail; if it is a manual slide rail, then it is unlocked. According to the position of the lock hole on the manual slide rail to be broken in, the position of the unlocking cylinder 20 is adjusted so that the unlocking head 21 is completely aligned with the lower lock hole position, and then the unlocking cylinder 20 drives the unlocking head 21 to move down until the unlocking head 21 is completely aligned with the lower lock hole position. Insert 21 into the lock hole to unlock. If it is an electric slide rail, no unlocking operation is required. Drive the servo motor 8, which drives the guide sleeve 10 to move along the guide rod 9. The connecting rod 12 moves with the guide sleeve 10, so that the tip of the lifting rod 3 is inserted into the set position. The lifting rods 3 on both sides work together to clamp and fix the lead screw. Drive the lifting cylinder 5, which drives the connecting plate 4 vertically. The connecting plate 4 moves upward along the guide rail 6. The lifting rod 3 fixed on the connecting plate 4 clamps the end of the lead screw and moves upward together with the connecting plate 4, thus... The lead screw is lifted, forcing the bracket on the lead screw to disengage from the outer rail. A suitable pin hole is selected on the flywheel 16 according to the rail specifications. Then, the end of the connecting rod 17 is inserted into the corresponding pin hole via a pin, completing the assembly of the connecting rod 17 and the flywheel 16. By driving the flywheel 16 to rotate around the vertical axis, the flywheel 16 drives one end of the connecting rod 17 to rotate. The other end of the connecting rod 17 is connected to the base 13, driving the base 13 and the outer rail fixed on the base 13 to reciprocate along the axial direction for a break-in operation. After the set break-in time is reached, the break-in of the rail is complete.

[0069] In this application, the axial direction refers to the length direction of the slide rail, that is... Figure 3 The left and right directions in this application, the vertical direction refers to... Figure 3 The up and down directions in the middle.
