Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts, and in particular relates to an automobile seat slide rail which can be adjusted forward, backward, left and right. Background Art

[0002] The aforementioned front, back, left, and right adjustments can be summarized as four-way adjustments, and the front and back adjustments can also be called longitudinal adjustments, while the left and right adjustments can be called lateral adjustments (the same below). From the literal meanings of front, back, left, and right, we can know that the car seat equipped with such a slide rail can be adjusted front and back according to the actual usage conditions, such as the actual needs of the passengers, and can also satisfy different passengers to find a position that is more suitable for their expectations through the left and right adjustment function.

[0003] For a long time, the design of car seat slides has been largely influenced and / or constrained by traditional design concepts or thinking patterns. In addition, passengers have formed a conventional acceptance and recognition of certain functions of car seats, such as adjustment functions (seat back angle adjustment function, seat fore-and-aft displacement adjustment function) during the use of car seats. As a result, car seat slides are still in a stereotyped and monotonous structural form and can only meet the state of fore-and-aft adjustment of car seats.

[0004] The main but not limited reasons for designing the car seat rails to only support front and rear adjustment but not support left and right adjustment at the same time may be the following: First, it is believed that front and rear adjustment can ensure the stability of the seat in a collision and reduce the risk of injury to the passengers. If left and right adjustment is added, safety may be affected due to structural strength; second, the seat belt design is based on the fixed position of the seat, and left and right adjustment may affect the effective restraint of the seat belt; third, it is believed that the space width in the car is limited, and left and right adjustment will take up more space; fourth, manufacturing cost, because adding left and right adjustment function on top of the front and rear adjustment function will increase design difficulty and manufacturing cost; fifth, passengers are accustomed to the existing demand for front and rear adjustment function.

[0005] However, the applicant believes that the above five situations can be attributed to the category of misunderstanding and cognitive bias factors. The key problem is that it is restricted by the bottleneck factor of structural design, because the motor as the driving mechanism of the known structural system of the front-back adjustable automobile seat slide rail is set between the middle of the length direction of a pair of movable slide rails that are parallel to each other and form a sliding pair with a pair of static slide rails. The forward and reverse working of the motor simultaneously drives the worm gear box fixed to the pair of movable slide rails to move forward and backward along the screw rod installed in the static slide rail cavity of the pair of static slide rails in a non-rotatable manner, thereby realizing the corresponding movement of the pair of movable slide rails, and finally the automobile seat is driven by the movable slide rail to move accordingly. Typical examples of such structures include "an electric slide rail, seat and automobile" recommended by CN115195544B, "an automobile seat slide rail with anti-deformation function and automobile thereof" provided by CN119239412A, and "an electric long slide rail for automobile seat" introduced by CN115123030A, etc.

[0006] If an attempt is made to expand the left and right slide rails on the basis of the above-mentioned patent, then the motor of the aforementioned driving mechanism of the structural system of the front-back adjustment mechanism will inevitably be interfered with. That is to say, since the motor as the driving mechanism, i.e., the driving mechanism of the slide rail moving forward and backward, and the motor frame for setting the motor span between a pair of movable slide rails, the motor frame and the motor set thereon will undoubtedly hinder the left and right moving slide rails. Specifically, according to design conventions, the motor as the driving mechanism of the structural system of the left-right adjustable automobile seat slide rail is set between the middle of the length direction of a pair of movable slide rails that are parallel to each other, i.e., the motor frame of the left-right adjustment mechanism carries the motor and is set in the middle of the length direction of a pair of front-back slide rails. Therefore, the movement of the aforementioned motor frame of the structural system of the front-back adjustable automobile seat slide rail together with its motor will be hindered by the motor frame of the structural system of the left-right adjustable automobile seat slide rail together with its motor, so that the adjustment functions of both, i.e., the front-back adjustment function and the left-right adjustment function, are completely lost. If the technical means is to raise the height of the left-right adjustable car seat slide rail so that there is a sufficient distance between it and the front-back adjustable car seat slide rail to avoid interference, it will cause the problem of losing one thing while gaining another. The so-called one thing is to avoid interference, but the so-called losing the other will significantly increase the height of the car seat, which is inappropriate from the perspective of design specifications, because it will cause uncomfortable posture for the driver and passengers, limited field of vision, inconvenient operation, reduced safety (high center of gravity), poor sense of space, affected seat stability (due to high center of gravity), etc.

[0007] From the above description, it can be seen that if the interference problem between the front and rear adjustable car seat slides and the left and right adjustable car seat slides can be avoided through reasonable design under the premise of the standard or conventional height of the car seat (car manufacturers usually set the seat height at 30-40cm based on ergonomics, and some seats are equipped with a height adjustment function), then the aforementioned four-way adjustment function can be fully utilized.

[0008] The applicant has conducted long-term and repeated simulation tests and found that the four-way adjustable seat rail can significantly improve the comfort, controllability and spatial flexibility of the seat by adding the left-right adjustment function on the basis of the front-back adjustment function. Take the driver's seat as an example: the left-right adjustment function allows the driver to fine-tune the seat position according to the body characteristics such as shoulder width and leg length, providing a more fitting body support and reducing fatigue from long-term driving; it is conducive to the driver to find the most ergonomic sitting posture, reduce the pressure on the waist and back, and improve the overall comfort; it can make the driver fully aligned with the steering wheel, pedals and instrument panel to ensure the control accuracy and response speed. Take the passenger seat as an example: passengers can fine-tune the left and right positions according to their own body shape and preferences until they get the most comfortable sitting position and reduce fatigue during long-distance rides; optimize leg space, for example, passengers can avoid friction with other parts in the car (such as doors, center consoles or passengers on the other side); facilitate social interaction, enhance social experience, and also help take care of children (closer to children); adapt to special needs, for people with limited mobility, left and right adjustments can find a position that is easier to get on and off the car; optimize personal space, because in the case of multiple people riding, left and right adjustments can help passengers adjust the seat position, obtain independent personal space, improve privacy and comfort, etc. As for the aforementioned increase in left and right adjustments, which may weaken safety, may affect the restraint of seat belts, and interference issues, etc., they are essentially caused by technical bias, because the range or amplitude of left and right adjustments is not large, and the purpose is only to optimize riding comfort and space allocation, rather than significantly changing the seat position. It is precisely because the left and right adjustment amplitude of the seat is relatively small that it will not affect the fixed point position of the seat belt. As for the interference problem between components, as long as the structural distribution is reasonable, there will be no interference problem.

[0009] In addition, although there is a patent with the publication number CN201457142U and the name "Four-way electric seat slide for automobile" in the public Chinese patent literature, its structural form involves the front and rear adjustment and the lifting adjustment of the automobile seat. Therefore, it has no reference significance for the technical design of adding the function of left and right adjustment on the basis of the front and rear adjustment of the automobile seat.

Figure 1 The car seat frame 3 is shown in FIG. Figure 1 It also has the technical connotation of the application example, which also confirms the applicant's Figure 1 Description, that is Figure 1 It is a structural diagram of an embodiment and application example of the present invention.

[0042] See also Figure 1Since the aforementioned automobile seat frame 3 belongs to conventional technology, and can even be called a known technology, and since the automobile seat frame 3 does not belong to the technical connotation of the present invention, the applicant only briefly describes it below. The left seat adjustment arm 31 (also called "slide rail left connecting arm") and the right seat adjustment arm 32 (also called "slide rail right connecting arm") of the structural system of the automobile seat frame 3 are parallel to each other, the front end of the left seat adjustment arm 31 is connected to the aforementioned first front fixed seat 2152 of the seat frame, and preferably adopts a hinged connection, while the rear end of the left seat adjustment arm 31 is connected to the aforementioned first rear fixed seat 22241 of the seat frame, the front end of the right seat adjustment arm 32 is connected to the aforementioned second front fixed seat 2153 of the seat frame, and preferably adopts a hinged connection, and the rear end of the right seat adjustment arm 32 is connected to the aforementioned second rear fixed seat 22251 of the seat frame. The left fixed connecting plate 33 of the seat back frame of the structural system of the automobile seat frame 3 is hinged with the left recliner 331 of the seat back, and the left recliner 331 of the seat back is arranged on the left recliner seat 3311 of the seat back, and the left recliner seat 3311 of the seat back is fixed to the left side of the left adjustment arm 31 of the seat back by screws. The right fixed connecting plate 34 of the seat back frame of the structural system of the automobile seat frame 3 is hinged with the right recliner 341 of the seat back, and the right recliner 341 of the seat back is arranged on the right recliner seat 3411 of the seat back, and the right recliner seat 3411 of the seat back is fixed to the right side of the right adjustment arm 32 by screws. The left and right recliners 331 and 341 of the seat back correspond to each other on the left and right sides, and are connected by a recliner driving shaft 35 of the structural system of the automobile seat frame 3, and the recliner driving shaft 35 synchronously drives the left and right recliners 331 and 341 of the seat back to rotate clockwise or counterclockwise to the required angle. The aforementioned recliner drive shaft 35 is driven by the recliner drive shaft motor 36 via the recliner drive shaft reduction box 37 , and the recliner drive shaft reduction box 37 is fixed to the right side of the aforementioned left seat adjustment arm 31 via the recliner drive shaft reduction box fixing seat 371 .

[0043] When the recliner drive shaft motor 36 is working, it drives the recliner drive shaft reducer 37, which in turn drives the recliner drive shaft 35, which in turn drives the left and right recliners 331, 341 of the chair back at the same time, thereby driving the left and right fixed connecting plates 33, 34 of the chair back frame to drive the chair back frame fixed thereto and adjust the forward or backward tilt angle of the chair back frame to the degree desired by the occupant.

[0044] When the passenger needs to adjust the car seat forward and backward or left and right, the passenger operates the control buttons arranged on the side or bottom of the car seat or other reasonable positions.

[0045] Take the front and back adjustment as an example, see Figure 1 and Figure 2The left and right motor output shafts 1311 and 1312 of the aforementioned movable rail front and rear displacement driving motor 131 of the structural system of the movable rail front and rear displacement adjustment mechanism 1 respectively drive the movable rail front and rear displacement left and right worm gear boxes 132 and 133, and the movable rail front and rear displacement left and right worm gear boxes 132 and 133 respectively drive the movable rail front and rear displacement left and right action screws 134 and 135 to rotate, so that the movable rail front and rear displacement left and right worm gear boxes 132 and 133 together with the movable rail front and rear displacement driving motor mounting frame 14 and the left and right movable rails 113 and 131 are moved forward or backward accordingly by the rotation of the movable rail front and rear displacement left and right action screws 134 and 135. The forward or backward movement depends on the clockwise or counterclockwise rotation state of the aforementioned movable rail front and rear displacement driving motor 131. Since the movable slide rail left-right movement adjustment mechanism 2 is mounted on the aforementioned movable slide rail front-back movement adjustment mechanism 1, when the aforementioned left and right movable slide rails 113, 123 are moved forward or backward for adjustment, the movable slide rail left-right movement adjustment mechanism 2 also moves forward or backward accordingly, and the aforementioned automobile seat frame 3 connected to the movable slide rail left-right movement adjustment mechanism 2 also moves forward or backward accordingly, thereby finally realizing the front-back position adjustment of the automobile seat as required.

[0046] Take left and right adjustment as an example, see Figure 1 and Figure 3 When the passenger operates the aforementioned related control buttons, the movable rail left-right displacement driving motor 231 of the structural system of the movable rail left-right displacement adjustment mechanism 2 starts working, and the front and rear output shafts 2311 and 2312 of the motor simultaneously drive the front and rear worm gear boxes 232 and 233 of the movable rail left-right displacement. The front and rear worm gear boxes 232 and 233 of the movable rail left-right displacement work synchronously and slide left or right (i.e. move, the same below) on the non-rotating front and rear worm gear box matching screws 234 and 235 respectively. Since the upper parts of the front and rear worm gear boxes 232 and 233 of the movable slide rail are respectively matched with the front and rear movable slide rail worm gear box embedding cavities 2133 and 2223, the front and rear movable slide rails 213 and 222 are driven to slide to the left or right respectively in the process of sliding to the left or right along the front and rear worm gear boxes matching screws 234 and 235 of the movable slide rail, and the front and rear movable slide rails 213 and 222 drive the aforementioned automobile seat frame 3 to move to the left or right accordingly, and finally realize the required adjustment of the left and right positions of the automobile seat. The movement of the aforementioned front and rear movable slide rails 213 and 222 to the left or right depends on the clockwise or counterclockwise working state of the movable slide rail left and right displacement driving motor 231.
