Description

Technical Field

[0001] The invention relates to the technical field of automobile seat slide rails, and in particular to a symmetrical metal slide rail with high peeling strength and a processing method thereof. Background Art

[0002] As an important part of the car seat, the seat rail not only bears the weight of the passengers, but also provides convenient seat adjustment functions. The mechanical locking structure is the key to ensure that the seat rail is stable, reliable, safe and comfortable.

[0003] Among them, the main performances of the seat slide rail include: peel strength, locking strength, unlocking force and free clearance, etc. The peel strength refers to the maximum force provided by the seat slide rail to prevent peeling from the contact part when the seat slide rail is deformed by force, and the indicator for evaluating the peel strength is the depth of the upper and lower rails interlocking with each other;

[0004] Referring to the automobile seat slide rail structure with publication number CN213734683U, the peeling strength of the slide rail is improved by setting a plurality of undercuts and matching buckles, but it still has some defects: when the vehicle collides, the bite depth of the upper and lower slide rails of the "W"-shaped slide rail used in the seat slide rail is consistent so that the energy absorbed by the two sides is consistent. When the collision force is greater than the peeling force, the seat slide rail is directly peeled off. In addition, in the application scenario of the seat slide rail, there is a lack of the function of intelligently controlling the slide rail to move in case of a collision to reserve leg space for the driver and passengers, that is, it is impossible to reserve leg space in time when the vehicle encounters a collision, and it is impossible to provide assistance for the driver and passengers to escape or be rescued quickly;

[0014] It is further configured as follows: the displacement detection module obtains the real-time displacement of the follower rail assembly and the vertical jump height of the follower rail assembly, wherein the real-time displacement L is measured by the overlapping length of the lower rail frame and the upper rail frame in the follower rail assembly, and the vertical jump height D is measured by the gravity sensor set in the follower rail assembly, and the displacement jump value WTz calculation formula is constructed , among which represents the initial overlap length of the lower rail and the upper rail, where , is the preset scale factor, is the preset fault tolerance factor, and .

DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1: In order to solve the technical problem that the peeling strength of the seat rail is not enough to meet the requirements of a stable structure with high collision force, the following technical solution is proposed:

[0039] Reference Figure 1 - Figure 7 As shown, in this embodiment, a symmetrical metal slide rail with high peeling strength includes a follower slide rail assembly, which is communicatively connected to a control system, and the follower slide rail assembly includes a lower rail frame 1 and an upper rail frame 2, a pair of upper rail frames 2 are connected by a connecting frame 4, an outer side of one end of the upper rail frame 2 is connected to a peeling-stopping plate 3, and two sides of the lower rail frame 1 respectively constitute a high cavity 11 and a low cavity 12, and the material thickness of the lower rail frame 1 on the side of the low cavity 12 is greater than that of the lower rail frame 1 on the side of the high cavity 11, and a filling belt 20 is arranged between the profiles on the side of the low cavity 12 for constituting the low cavity 12;

[0040] The upper rail frame 2 is arranged in the high cavity 11 through the anti-stripping plate 3 and is interlocked with the lower rail frame 1 in the longitudinal direction; a plurality of groups of pull-in holes 5 are provided on both sides of the upper rail frame 2, and an anti-slip seat 6 is provided at the middle position of the inner bottom end of the lower rail frame 1, and an extension table 18 matching the pull-in hole 5 is installed on both sides of the upper end of the anti-slip seat 6, and a screw rod 7 connected to the driving structure is installed in the middle of the anti-slip seat 6, and a moving seat 17 connected to the upper rail frame 2 is connected to the outer surface of the screw rod 7;

[0041] The upper end of the anti-peeling plate 3 faces outward and is provided with a buckle groove 10 at the end, and a plurality of buckle strips 14 are installed at intervals on the inner side of the lower rail frame 1 corresponding to the buckle groove 10; a protrusion 9 facing outward is opened on the upper end of the inner side of the lower rail frame 1, and a support rod 13 is installed on the upper end of the upper rail frame 2, and an upper roller 8 corresponding to the protrusion 9 is rotatably installed on the upper end of the support rod 13, and a lower roller 19 corresponding to the protrusion 9 is installed on the end of the upper rail frame 2 away from the anti-peeling plate 3, and the upper roller 8 and the lower roller 19 are respectively arranged in the high cavity 11 and the low cavity 12, and respectively provide relative sliding support between the upper rail frame 2 and the lower rail frame 1, so as to improve the structural stability of the follower slide rail assembly during operation;

[0042] When the upper rail frame 2 and the lower rail frame 1 overlap, the upper roller 8 and the lower roller 19 can also jointly provide smooth operation of the follow-up slide rail assembly to avoid jamming caused by overlapping deviation. At the same time, when the upper rail frame 2 and the lower rail frame 1 slide through the connecting frame 4, the outer side of the connecting frame 4 moves along the guide groove 22 on the inner side of the upper end of the lower rail frame 1, thereby achieving a smooth relative movement state.

[0043] Both sides of the extension platform 18 are provided with beveled edges 21, and the bottom ends of the beveled edges 21 are aligned with the upper sides of the pull-in holes 5. Here, the pull-in holes 5 are aligned with the extension platform 18. When the upper rail frame 2 is deformed and pulled upward, the two sides of the upper rail frame 2 are brought together to form a buckle with the extension platform 18 in the middle. In addition, the multiple groups of pull-in holes 5 and the extension platform 18 are arranged together, so that when the seat body and the upper rail frame 2 are pulled upward, the lower rail frame 1 can also be pulled upward as a whole, thereby increasing the difficulty of peeling and improving the peeling strength.

[0044] A plurality of installation holes are provided at both ends of the lower rail frame 1 and the upper rail frame 2 at intervals in the length direction, and lower locking rods 15 and upper locking rods 16 are alternately installed on the lower rail frame 1 and the upper rail frame 2 through the installation holes, the lower locking rod 15 is connected to the vehicle floor, and the upper locking rod 16 is connected to the seat base; by connecting the lower locking rod 15 to the vehicle floor and the upper locking rod 16 to the seat base, the seat slide has an initial stable structure during installation, so that when the vehicle collides, the vertical jump value of the vehicle itself is the same as that of the seat slide, thereby facilitating subsequent intelligent control actions.

[0045] Basic principle: Figure 5 To illustrate, the upper rail frame 2 and the lower rail frame 1 form a mutually interlocking structure, and the high cavity 11 and the low cavity 12 in the lower rail frame 1 respectively form the passing space of the upper rail frame 2, so that when the entire seat slide is subjected to external force deformation, the overlapping length of the high cavity 11 on the right side and the upper rail frame 2 is much greater than the overlapping length of the upper rail frame 2 on the left side and the low cavity 12, so that the right side of the entire follower slide assembly can absorb the energy generated by the external force deformation through sufficient deformation during the force process, thereby producing an effect that is difficult to peel off;

[0046] It is important to explain here that: while the high and low interlocking cavities jointly form a difficult-to-peel-off effect, a buckling structure is also added between the upper rail frame 2 and the lower rail frame 1. When the upper rail frame 2 is deformed by external force and peeled upward, the upper rail frame 2 is first subjected to force to move upward and deform. The upper rail frame 2 is connected to the seat base by the locking rod 16 and stretched upward. At this time, the buckle holes 5 of the upper rail frame 2 are close to each other and move upward, and the extension platform 18 on the anti-slip seat 6 on the lower rail frame 1 is just buckled into the buckle hole 5, thereby enhancing the structural strength of the upper rail frame 2 and the lower rail frame 1 during the peeling process, and the overall peeling strength is improved with the bite effect.

[0047] In addition, a locking structure is added to the outer side of the anti-peeling plate 3 with the lower rail frame 1. Specifically, when the upper rail frame 2 and the lower rail frame 1 are subjected to force to peel and separate, the anti-peeling plate 3 on the side of the high cavity 11 slides downward when the upper rail frame 2 peels and separates upward, and the peeling and separation action of the upper rail frame 2 being pulled outward from the middle of the upper rail frame 2 causes the upper rail frame 2 to separate from the lower rail frame 1, so that the anti-peeling plate 3 is expanded outward, and the buckle groove 10 on the anti-peeling plate 3 is meshed with the buckle strip 14, so as to form a locking structure, which together with the bite structure and the buckle structure constitutes the difficult peeling effect of the seat slide rail when it is subjected to external force deformation, and finally achieves high peeling strength;

[0048] Based on the above, it can be learned that the mutual sliding space of the follower slide rail assembly is formed by different interlocking cavities, so that the follower slide rail assembly has a difficult-to-peel-off effect when it is deformed by a collision. The joint setting of the interlocking structure and the snap-fit ​​structure can effectively improve the peeling strength of the follower slide rail assembly, and the asymmetric structural design can effectively improve the structural strength of the seat slide rail. The two combined generate high peeling strength to meet the stable structural requirements of high collision forces.

[0049] Embodiment 2: Based on Embodiment 1, this embodiment further optimizes the control system therein intelligently to solve the technical problem that the leg space of the driver and passengers cannot be reserved in time when a collision occurs.

[0050] The control system includes a processor, a displacement detection module, an obstacle detection module, a deployment analysis module and a drive module;

[0051] The displacement detection module is used to collect the displacement jump value WTz of the follower slide rail assembly during the operation of the vehicle, and send the displacement jump value WTz to the deployment analysis module through the processor; the obstacle detection module is used to obtain the real-time distance between the follower slide rail assembly and the obstacles on the front and rear sides, and send it to the deployment analysis module;

[0052] The deployment analysis module combines the received displacement jump value WTz and the real-time distance to the obstacle to form a deployment coefficient, compares and analyzes the deployment coefficient with the preset deployment coefficient threshold to generate positive feedback adjustment signals and negative feedback adjustment signals, and sends the positive feedback adjustment signals and negative feedback adjustment signals to the driving module to execute related actions;

[0053] The displacement detection module obtains the real-time displacement of the follower rail assembly and the vertical jump height of the follower rail assembly. The real-time displacement L is measured by the overlapping length of the lower rail frame 1 and the upper rail frame 2 in the follower rail assembly, and the vertical jump height D is measured by the gravity sensor set in the follower rail assembly. The displacement jump value WTz calculation formula is constructed , among which represents the initial overlap length of the lower rail 1 and the upper rail 2, where , is the preset scale factor, is the preset fault tolerance factor, and ;

[0054] The obstacle detection module obtains the distance between the follower rail assembly and the front obstacle and marks it as , get the distance between the follower rail assembly and the rear obstacle and mark it as ,Will and The distances to the initial front and rear obstacles respectively To calculate the difference, if - is a positive number or - If it is a negative number, it means that the upper rail frame 2 in the follower slide assembly overlaps and shifts to the rear of the lower rail frame 1;

[0055] like - is a negative number or - If it is a positive number, it means that the upper rail frame 2 in the follower rail assembly overlaps and shifts to the front of the lower rail frame 1. In combination with the above, the obstacle detection module is used to measure the distance between the front and rear obstacles of the follower rail assembly, the glove box and the rear seat; when , The distance determination result from the front and rear obstacles is that when the upper rail frame 2 in the follower rail assembly overlaps and shifts to the front of the lower rail frame 1, it means that the entire seat is close to the glove box. , The result of the distance determination to the front and rear obstacles is that the upper rail frame 2 in the follower slide rail assembly overlaps and shifts to the rear of the lower rail frame 1: it indicates that the entire seat is close to the rear seat, directly providing a related start signal for the subsequent execution action;

[0056] The comprehensive analysis process in the deployment analysis module is as follows: when the deployment analysis module receives the displacement jump value and the real-time distance to the obstacle, the displacement jump value and the real-time distance to the obstacle are added to obtain the deployment coefficient;

[0057] When the adjustment coefficient is greater than the adjustment coefficient threshold, a negative feedback adjustment signal is generated; when the adjustment coefficient is less than or equal to the adjustment coefficient threshold, a positive feedback adjustment signal is generated, and both the negative feedback adjustment signal and the positive feedback adjustment signal are sent to the driving module to execute related actions;

[0058] When the drive module receives the negative feedback regulation signal, the drive structure (not shown in the figure) connected to the screw rod 7 is started, driving the screw rod 7 to rotate clockwise. The screw rod 7 drives the moving seat 17 to move, and the moving seat 17 drives the upper rail frame 2 to move backward, driving the seat as a whole to move backward. and The distances from the initial front and rear obstacles If they are the same, stop running;

[0059] When the drive module receives the positive feedback regulation signal, the drive structure connected to the screw rod 7 starts, driving the screw rod 7 to rotate counterclockwise. The screw rod 7 drives the moving seat 17 to move, and the moving seat 17 drives the upper rail frame 2 to move forward, driving the seat as a whole to move backward. and The distances from the initial front and rear obstacles If the two seats are the same, the system stops running. At this time, the space before and after the seats can generate enough reserved space after the drive module is started, so as to avoid the problem that the gap between the seats is too small in the event of a collision, resulting in the driver and passengers being unable to escape smoothly or the rescue space being too small.

[0060] The operating principle of the control system of the present invention is as follows:

[0061] When the vehicle collides, the gravity sensor on the seat follower rail assembly triggers the operation control, and obtains the distance of obstacles in front and behind the current seat in real time through the obstacle detection module. The current leg space of the driver and passenger is determined by the obstacle distance, and the execution action is taken;

[0062] Action 1: Determine the current required moving direction based on the obstacle distance. Specifically, the distance between the obstacle in front of and behind the seat is compared with the preset distance. If the space does not meet the requirements for the driver and passengers to escape or be rescued, action 2 is initiated.

[0063] Action 2: Use the displacement detection module to determine the required moving length based on the overlapping length between the upper rail frame 2 and the lower rail frame 1 in the current follower slide rail assembly, compare and analyze it with the distance between the front and rear obstacles, and make the drive structure control the lead screw 7 to control the corresponding rotation direction and feed distance, so that the overlapping length between the upper rail frame 2 and the lower rail frame 1 meets the requirements for the escape or rescue of the driver and passengers;

[0064] It should be noted that: when the vehicle is hit and the seat is deformed, the gravity sensor obtains the vertical jump height value of the current seat slide rail. When the vertical jump height value exceeds the preset vertical jump height extreme value, a curve drawing signal is sent to the displacement detection module, the obstacle detection module and the drive module, and the above three modules jointly draw a "displacement curve" and store it in the processor, wherein the processor is built into the seat slide rail. When a vehicle collision accident occurs, the "displacement curve" records the entire process of displacement adjustment of the seat slide rail, so as to facilitate subsequent accident review and make targeted structural repair and optimization;

[0065] In combination with Example 1 and Example 2, it can be seen that the present invention can not only utilize different interlocking cavities to form the mutual sliding space of the follower slide rail assembly, so that the follower slide rail assembly has a difficult-to-peel-off effect when it is deformed by a collision, and the joint setting of the interlocking structure and the snap-fit ​​structure can effectively improve the peeling strength of the follower slide rail assembly; it can also utilize the intelligent control system to form automatic adjustment control of the seat slide rail when the vehicle collides, so as to realize intelligent adjustment of the front and rear reserved space of the seat by pre-determining the front and rear obstacles combined with the displacement action, so as to prevent the problem of insufficient leg space reserved for the driver and passengers after a vehicle collision, resulting in the inability to escape and be rescued; the mutual coordination of the two can enable the symmetrical metal guide rail to achieve high peeling strength and timely early warning action implementation in vehicle applications.

[0066] Embodiment 3: The present invention also provides a method for processing a symmetrical metal slide rail with high peel strength, comprising the following steps:

[0067] Step 1: Material selection: Select the materials of the lower rail frame 1, the upper rail frame 2, and the anti-stripping plate 3, wherein the lower rail frame 1 and the upper rail frame 2 are limited to aluminum profiles, and the anti-stripping plate 3 is selected to be a steel profile;

[0068] Step 2: stamping: using a stamping machine to stamp the lower rail frame 1, the upper rail frame 2 and the anti-stripping plate 3 to form the basic shape of the slide rail, and bending the lower rail frame 1, the upper rail frame 2 and the anti-stripping plate 3;

[0069] Step 3: Welding and cutting, fine welding and fine-tuning of each component, wherein the welding between the anti-stripping plate 3 and the upper rail frame 2 adopts a plasma welding method;

[0070] Step 4: Surface treatment: spray paint or electroplating the surface of each component to improve wear resistance and oxidation resistance, and ultimately increase service life;

[0071] Step 5: Assemble the components into a slide rail assembly and perform quality inspection to ensure that the slide rail assembly meets production requirements and relevant regulations.
