Description
Technical Field
[0001] The invention relates to the technical field of automobile seats, and in particular to an automobile seat adjustment mechanism and a working method thereof. Background Art
[0002] There are many types of seat adjustment devices available, the most common of which are backrest unlocking and slide rail unlocking. The seat back unlocking structure uses mechanical gears, unlocking rods, spring return systems and connecting rod mechanisms to achieve flexible adjustment and locking of the backrest angle; the seat front and rear unlocking structure is a simple and effective design based on slide rails, lock pins, springs and unlocking rods. It allows users to manually adjust the front and rear position of the seat, and ensures that the seat is firmly locked after releasing the unlocking rod through a spring return mechanism.
[0003] In actual use, the mechanisms for unlocking the backrest and the slide rail are inconvenient for people to use because they are separately arranged and need to be unlocked by two unlocking rods respectively. In view of the above problems, some improvements have been proposed in the prior art. For example, the patent with authorization announcement number CN110641325B discloses an easy-entry unlocking mechanism for a second row of SUV seats, which is installed in a seat. The seat includes a slide rail installed on the floor of the car, a slide rail lock matched with the slide rail lock, a cushion frame, a backrest frame, and an easy-entry unlocking handle. The easy-entry unlocking mechanism includes a first cable, a second cable, a third cable, a fourth cable, a fifth cable, a one-to-two cable, a first wiring harness junction box, a second wiring harness junction box, and a straight-line driving plate and a bent driven plate rotatably installed on the outside of the second angle adjuster; the tail of the driving plate is simultaneously in contact with the head of the driven plate and the head of the angle adjuster unlocking plate of the second angle adjuster, and the driving plate can drive the driven plate and the angle adjuster unlocking plate to rotate when the driving plate rotates. The beneficial effects of the present invention are: not only can the angle adjuster and the slide rail lock be unlocked with one key, but the front and rear adjustment of the seat back and the front and rear adjustment of the seat cushion can also be achieved independently.
[0004] Although the above improvement can adjust the front and back of the seat and the backrest at the same time, a total of three unlocking parts are provided, and the overall structure is relatively complex and not easy for personnel to operate. Summary of the invention

[0032] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] Example 1
[0034] like Figure 1 , 2 As shown, a vehicle seat adjustment mechanism comprises:
[0035] A front-to-back adjustment mechanism 1, the front-to-back adjustment mechanism comprising a moving assembly 11, a front-to-back locking assembly 12 and a first unlocking member 13, the moving assembly can drive the seat cushion to move forward and backward after the first unlocking member unlocks the front-to-back locking assembly;
[0036] A backrest adjustment mechanism 2, arranged at the rear end of the seat cushion, comprising a recliner shaft 21, a recliner 22 and a second unlocking member 23, and the backrest can rotate around the shaft after the second unlocking member unlocks the recliner;
[0037] The linkage adjustment mechanism 3 includes a linkage component 31 and a third unlocking member 32. The linkage component is connected to the first unlocking member 13 and the second unlocking member 23. The third unlocking member is used to drive the first unlocking member to unlock the front and rear locking components or drive the second unlocking member to unlock the angle adjuster.
[0038] The linkage assembly 31 includes a first rotating shaft 311, to which a cam structure 312 is connected. One end of the first rotating shaft is also fixedly connected to a third unlocking member 32, which is a third rotating handle. The first unlocking member 13 includes a first pull rod, and the second unlocking member 23 includes a second rotating handle.
[0039] The cam structure 312 includes a first cam 3121, and the third rotating handle drives the rotating shaft to rotate in one direction so that the first cam drives the first unlocking member to unlock the front and rear locking components, and the third rotating handle drives the rotating shaft to rotate in the other direction so that the first cam drives the second unlocking member to unlock the angle adjuster.
[0040] Since the front and rear moving mechanism is located at the bottom of the seat, the front and rear locking components 12 and the first unlocking member 13 are also located at the bottom of the seat, which is far away from the third unlocking member. Therefore, in this embodiment, the lock buckle in the first unlocking member can be connected to the first pull rod by a cable or an extension rod, so as to realize a linkage connection with the third unlocking member. The first cam 3121 can push the first pull rod to move during the rotation process, thereby driving the lock buckle to unlock; and the second unlocking member 23 adopts the structure of a rotating handle in a general car seat, so the second rotating handle is taken as an example for explanation. In this embodiment, a sliding mechanism 4 is used for control. The sliding mechanism 4 includes a first slide groove 41, and a sliding block 42 is slidably connected in the first slide groove. The sliding block is provided with a second slide groove 43 perpendicular to the first slide groove. The end of the second rotating handle away from the rotation center is slidably connected in the second slide groove. With this structure, the second rotating handle can be rotated, thereby realizing the unlocking of the recliner.
[0041] In conventional structures, unlocking is performed by pulling the handle upwards. In order to unlock by pulling the third rotating handle downwards, a reversing structure is added. The reversing structure uses a lever or a gear. The lever structure 5 used in this embodiment cooperates with the sliding mechanism 4 for control.
[0042] In this embodiment, the third rotating handle is rotated counterclockwise upward to unlock the angle adjuster, and the third rotating handle is rotated clockwise downward to unlock the front and rear locking components 12. During the rotation process, the first cam 3121 can cooperate with the sliding mechanism through the lever structure to push the first pull rod to move, thereby driving the lock to unlock.
[0043] In this embodiment, a positioning mechanism is provided to provide a certain resistance for the third rotating handle in the locked position to help maintain its static state. The positioning component can be a first spring. When the front and rear locking components and the angle adjuster are in the locked state, that is, when the front and rear positions of the seat and the backrest are fixed, the third rotating handle, the second pulling handle, and the first pulling handle are maintained in the middle position under the action of the first spring. Preferably, there are more than two first springs, and one is provided at each end of the third rotating handle so that in the locked state, the respective forces on both sides plus the spring forces at their respective ends are equal, so that the third rotating handle maintains a stable state when locked. It can be understood that the number of first springs is not limited to two, and multiple or multiple groups can be provided on each side. The front and rear adjustment mechanism and the backrest adjustment mechanism can also add first springs in their respective components.
[0044] In order to further increase the stability, the third rotating handle can be kept in a fixed position when locked, and the positioning mechanism can also be a stopper at this position, and a stopper can be added on both sides of it. The end of the stopper close to the third rotating handle can be a structure with a gradually smaller width, and a second spring is provided at the bottom. When locked, the third rotating handle is limited by a certain force from both sides, and the force should not be too large to prevent a large force from being required when manually pulling. Preferably, when the stopper is pulled over, it will automatically reset under the action of the first spring. In order to achieve this function, when the first spring pushes the third rotating handle to reset and pass the stopper, the force of the stopper at this location should be less than the force of the first spring.
[0045] Furthermore, a push block structure can also be directly adopted. A slide groove is provided inside the third rotating handle, and a push block is provided in the slide groove. The push block is connected to a pressing block. When the third rotating handle needs to be pulled, the pressing block is pressed to move the push block to the stop plate, and the stop plate is pushed away to release the third rotating handle so that it can be pulled, thereby avoiding safety problems caused by the instability of the third rotating handle during normal driving.
[0046] Optionally, a micro-groove structure may be used to provide a certain resistance to the third rotating handle in the locked position to help keep it in a stationary state.
[0047] Embodiment 1 is the basic solution of the present invention, which can realize the control of the forward and backward movement of the seat by unlocking the position adjustment mechanism alone or the control of the backrest angle by unlocking the backrest adjustment mechanism alone through pulling a handle.
[0048] The aforementioned front and rear adjustment mechanism and backrest adjustment mechanism are prior art and are widely used in automobile seats, and will not be described in detail herein.
[0049] Example 2
[0050] like Figure 3 ,4 As shown, different from Example 1, the cam structure 312 includes a second cam 3122 and a third cam 3123 arranged on different axes of the first rotating shaft, the third rotating handle drives the rotating shaft to rotate A° in one direction, the second cam 3122 drives the first unlocking member to unlock the front and rear locking components, the third rotating handle drives the rotating shaft to rotate C° in the other direction, and the third cam 3123 drives the second unlocking member to unlock the angle adjuster.
[0051] The use of a double cam structure can avoid the need for a lever structure, and the two cams work independently to respectively unlock the front and rear locking components and the recliner.
[0052] In this embodiment, the third rotating handle is rotated counterclockwise upward to unlock the recliner, and the third rotating handle is rotated clockwise downward to unlock the front and rear locking components 12 .
[0053] Example 3
[0054] like Figure 5 , 6 As shown, the cam structure 312 includes a second cam connected to the first unlocking member and a third cam connected to the second unlocking member, the third rotating handle drives the rotating shaft to rotate in one direction a~A°, the second cam drives the first unlocking member to unlock the front and rear locking components, the third rotating handle drives the rotating shaft to rotate in one direction A~A+B°, the second cam drives the first unlocking member to unlock the front and rear locking components, and the third cam drives the second unlocking member to unlock the angle adjuster; the third rotating handle drives the rotating shaft to rotate in another direction c~C°, the third cam drives the second unlocking member to unlock the angle adjuster, the third rotating handle drives the rotating shaft to rotate in another direction C~C+B°, the third cam drives the second unlocking member to unlock the angle adjuster, and the second cam drives the first unlocking member to unlock the front and rear locking components, A+B+C=360°.
[0055] In order to achieve the above functions, the second cam and the third cam need to be relatively large to improve the transmission control of the unlocking member within their rotation angle.
[0056] The specific working principle is: when the second cam rotates in the range of a~A° in one direction, the second cam will drive the first unlocking member to unlock the front and rear locking components, and the third cam will not drive the second unlocking member to unlock the recliner; when the third cam rotates in the range of c~C° in another direction, the third cam will drive the second unlocking member to unlock the recliner, and the second cam will not drive the first unlocking member to unlock the front and rear locking components; and when the second cam rotates in one direction of A~A+B° or the second cam rotates in another direction of C~B+C°, since A+B+C=360°, these two situations are the same. At this time, the second cam drives the first unlocking member to unlock the front and rear locking components, and the third cam drives the second unlocking member to unlock the recliner.
[0057] By pulling a handle, it is possible to unlock the position adjustment mechanism alone to control the forward and backward movement of the seat, unlock the backrest adjustment mechanism alone to control the backrest angle, or unlock the position adjustment mechanism to control the forward and backward movement of the seat and unlock the backrest adjustment mechanism to control the backrest angle at the same time.
[0058] Example 4
[0059] The present invention also discloses a method for adjusting the vehicle seat adjustment mechanism, comprising the following steps:
[0060] 1) When the front and rear position of the seat needs to be adjusted, the third rotating handle is rotated to drive the first pull rod to move and unlock the front and rear locking components 12;
[0061] 2) When the backrest angle needs to be adjusted, the third rotating handle is rotated in another direction to drive the first pull rod to move and complete the unlocking of the front and rear locking components 12.
[0062] Optionally, based on Example 1, the method further comprises: in step 1), the third rotating handle drives the rotating shaft to rotate in one direction so that the first cam drives the first unlocking member to unlock the front and rear locking components; in step 2), the third rotating handle drives the rotating shaft to rotate in another direction so that the first cam drives the second unlocking member to unlock the angle adjuster.
[0063] Optionally, based on Example 3, in step 1), the third rotating handle drives the rotating shaft to rotate a to A° in one direction, and the second cam drives the first unlocking member to unlock the front and rear locking components; in step 2), the third rotating handle drives the rotating shaft to rotate C° in the other direction, and the third cam drives the second unlocking member to unlock the recliner;
[0064] It also includes step 3) when it is necessary to adjust the front and rear position of the seat and the backrest angle at the same time, rotate A°~A+B° in one direction or C°~C+B° in another direction, the second cam drives the first unlocking member to unlock the front and rear locking components, and the third cam drives the second unlocking member to unlock the angle adjuster.
[0065] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
