Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile seat structures, in particular to an integrated motion control unlocking device, a seat and an automobile. Background Art
[0002] For seat structures with a folding function, the most common folding method is to first fold the backrest onto the seat cushion, and then fold or adjust the seat cushion and the folded backrest together to a predetermined position. Therefore, the unlocking mechanism currently provided on automobile seats includes at least two unlocking steps, each of which is performed in sequence. This makes the entire unlocking mechanism complex, costly, and the overall weight of the seat heavy. In order to solve the problem of the complex unlocking structure and complicated unlocking action of seats with a folding function in the prior art, the inventors have designed an invention patent for a folding automobile seat, such as the patent publication number CN116901800A and the invention name "One-button Unlocking." Through the interaction of specific components, one-button unlocking of the backrest folding and the seat cushion folding can be achieved, effectively simplifying the unlocking structure of the seat and making unlocking easier.
[0003] Although the above patent simplifies the unlocking structure and makes the unlocking process more convenient and easy, there are still some problems in actual use: as described in the patent specification of publication number CN116901800A, when the operating handle is pulled to rotate the rotating plate counterclockwise, the pin is disengaged from the slot, and then the backrest frame is rotated to flip / fold forward. When the backrest frame flips forward, it will drive the forward flip clockwise rotation, and then apply force to the column to make the column and the upper part of the first movable plate rotate backward synchronously (counterclockwise), and at the same time drive the second movable plate to rotate counterclockwise. During this process, the upper part of the second movable plate is tilted up and the cable is pulled upward, which can finally unlock the locking structure (i.e., the ground lock) of the rear support of the seat frame. Although this structure can drive the first movable plate to rotate by driving the column, thereby driving the subsequent unlocking process, the column is driven to move by the fixed plate during the rotation of the backrest frame, and the fixed plate is a plate-like structure fixedly connected to the backrest by welding. Not only is the installation of the fixed plate more complicated, but the fixed connection point between the fixed plate and the backrest frame is located at a different position from the rotation connection point between the backrest frame and the seat frame. As a result, when the backrest frame rotates relative to the seat frame and the fixed plate pushes the column to move synchronously, the fixed plate is subjected to greater force and is easily deformed and damaged during use, resulting in poor stability in the unlocking process. Utility Model Content
[0004] The utility model aims to provide an integrated motion control unlocking device, a seat and a car, so as to solve the problem of complex seat unlocking structure and poor stability in the prior art.
[0005] To solve the above problems, the present invention adopts the following technical solution: an integrated motion control unlocking device, including a seat frame and a backrest frame, a rotating shaft fixedly connected to the backrest frame, a first movable plate rotatably connected to the seat frame, the backrest frame is rotatably connected to the seat frame through the rotating shaft, and a driving member for driving the first movable plate to rotate is fixedly connected to the rotating shaft.
[0006] The principle and beneficial effects of the present solution are as follows: in the present application, the backrest frame and the seat frame are rotatably connected by a rotating shaft, and the rotating shaft is fixedly connected to the backrest frame. When the operating handle in the prior art is pulled to rotate the rotating plate counterclockwise, the pin is disengaged from the slot, and the locking effect of the pin on the backrest frame disappears. At this time, the backrest frame can be manually rotated, and the rotating shaft will be driven to rotate during the rotation of the backrest frame. When the rotating shaft rotates, it can drive the driving member to rotate, so that the driving member drives the first movable plate to rotate, and the first movable plate drives the second movable plate in the prior art to rotate. The second movable plate pulls the zipper to unlock the locking structure (i.e., the ground lock) of the rear support of the seat frame. Compared with the prior art method of using a fixed plate welded to the backrest frame to drive the first movable plate to rotate, the structure of the fixed plate is complicated and inconvenient to install in a seat with a complex internal structure and limited space. In the present application, the driving member is directly fixedly connected to the rotating shaft, reducing the number of parts and integrating the unlocking control of the rotation center of the backrest frame. This makes the structure of the unlocking device simpler, more convenient to install, and lower in cost. In addition, in the present application, the driving member is directly connected to the rotating shaft, and the rotation center of the driving member coincides with the rotation center of the rotating shaft, so that when the driving member drives the first movable plate to rotate, the force can be transmitted stably and conveniently, making the unlocking more stable.
[0007] Preferably, as an improvement, the driving member includes a shift fork fixedly connected to the rotating shaft, and the first movable plate is fixedly connected to a column, which is located on the rotation path of the shift fork.
[0008] In this solution, the driving member is a fork structure, which is fixedly connected to the rotating shaft. When the rotating shaft rotates with the backrest frame, it can drive the fork to rotate. The column is located on the rotation path of the fork, so that the fork drives the column and the first movable plate to rotate at the same time to achieve unlocking. The plug-in and unplug structure is stable and easy to install, and can stably transmit the force to complete the unlocking action.
[0009] Preferably, as an improvement, the shift fork is provided with an arc-shaped surface that cooperates with the outer wall of the cylinder.
[0010] In this solution, the column is a cylindrical structure, and an arc surface is provided on the fork to match the outer wall of the main body, so that when the fork rotates and contacts the column, there is a larger contact area, so that the fork can push the column to move more stably and smoothly, thereby improving the smoothness and stability of the unlocking process.
[0011] Preferably, as an improvement, one end of the column is fixedly connected to the first movable plate, and the other end is fixedly connected to a limiting member, and a limiting space cooperating with the shift fork is enclosed between the limiting member and the first movable plate.
[0012] In this solution, a limiting space is formed by the limiting member and the first movable plate. When the shift fork rotates to push the column to move and complete the unlocking, the shift fork is located in the limiting space. The limiting member can limit and position the shift fork, so that the shift fork can drive the unlocking more stably.
[0013] Preferably, as an improvement, the limiting member includes a retaining ring fixedly connected to the end of the column, and the diameter of the retaining ring is larger than the diameter of the column.
[0014] In this solution, by providing a retaining ring with a diameter larger than that of the column, the retaining ring and the first movable plate can enclose a limiting space, which has a simple structure and a good limiting effect.
[0015] Preferably, as an improvement, a rotating sleeve is provided between the rotating shaft and the seat frame.
[0016] In this solution, the rotating sleeve is used to reduce the friction between the rotating shaft and the seat frame, which is conducive to the long-term and stable operation of the unlocking device.
[0017] Preferably, as an improvement, a washer is fixedly connected to the backrest frame, the washer is coaxially arranged with the rotating shaft and the washer is located between the backrest frame and the seat frame.
[0018] In this solution, a washer is fixed on the backrest frame, the washer is coaxially arranged with the rotating shaft and the washer is located between the backrest frame and the seat frame. When the backrest frame rotates and drives the rotating shaft and the washer to rotate, the washer plays a supporting role between the backrest frame and the seat frame, which can avoid large-area contact between the seat frame and the backrest frame, thereby reducing the friction between the seat frame and the backrest frame during the relative rotation of the backrest frame and the seat frame, which is beneficial to reduce wear and reduce friction noise or abnormal noise.
[0019] Preferably, as an improvement, one side of the gasket is in contact with the backrest frame, and the other side is in contact with the rotating sleeve.
[0020] In this solution, one side of the gasket is in contact with the backrest frame and the other side is in contact with the rotating sleeve. During the unlocking rotation process, the gasket and the rotating sleeve rotate relative to each other to avoid relative friction between the gasket and the seat frame. Therefore, the material of the rotating sleeve can be set to flexible and wear-resistant parts such as wear-resistant rubber, thereby further reducing the wear of the gasket, noise or abnormal sound during the rotation unlocking process, making the unlocking process smoother and more stable.
[0021] A seat comprising the integrated motion control unlocking device; and a car comprising the integrated motion control unlocking device or the seat.
[0022] The integrated motion control unlocking device is provided on the seat, which effectively reduces the number of parts and integrates the integrated motion control unlocking of the backrest frame rotation center, making the structure of the unlocking device simpler and the unlocking process more stable.

[0027] Figure 5 This is a schematic diagram of the second embodiment of the present invention. DETAILED DESCRIPTION
[0028] The following is further described in detail through specific implementation methods:
[0029] The reference numerals in the drawings of the specification include: seat frame 1, backrest frame 2, rotating shaft 3, first movable plate 4, second movable plate 5, limit plate 6, zipper 7, shift fork 8, column 9, rotating sleeve 10, washer 11, operating handle 12, pin 13, slot 14, and retaining ring 15.
[0030] Example 1
[0031] This embodiment is as shown in the attached Figure 1 As shown: An integrated motion-controlled unlocking device comprises a seat frame 1 and a backrest frame 2. A rotating shaft 3 perpendicular to the plane of the backrest frame 2 is fixedly connected to the backrest frame 2 by welding. The backrest frame 2 is rotatably connected to the seat frame 1 via the rotating shaft 3. Simultaneously, a first movable plate 4 is rotatably connected to the seat frame 1 via a pin, and a second movable plate 5 is rotatably connected to the seat frame 1 coaxially with the first movable plate 4. A limit plate 6 is integrally formed on the second movable plate 5, contacting the first movable plate 4. A zipper 7 is connected to the second movable plate 5. When the first movable plate 4 rotates counterclockwise, it pushes the second movable plate 5 to rotate counterclockwise, causing the second movable plate 5 to pull the zipper 7 to unlock.
[0032] Combine Figure 1 and Figure 2In this embodiment, a driving member for driving the first movable plate 4 to rotate and unlock the zipper 7 is fixedly connected to the rotating shaft 3. The driving member is a shift fork 8 welded to the top of the rotating shaft 3. In order for the shift fork 8 to more stably drive the first movable plate 4 to rotate, a column 9 arranged parallel to the rotating shaft 3 is welded and fixed to the first movable plate 4. The column 9 is located on the rotation path of the shift fork 8 following the rotation of the rotating shaft 3. That is, when the shift fork 8 rotates clockwise, the shift fork 8 can apply pressure to the column 9 to drive the first movable plate 4 to rotate counterclockwise, ultimately unlocking the zipper 7. At the same time, in order for the shift fork 8 to more stably push the column 9 to move, in this embodiment, the shift fork 8 has an integrally formed curved surface on the side facing the column 9. When the shift fork 8 pushes the column 9 to move, the curved surface contacts the column 9, which increases the contact area between the shift fork 8 and the column 9, thereby completing the unlocking action more stably.
[0033] Combine Figure 3 and Figure 4 In this embodiment, a rotating sleeve 10 is mounted and fixed on the seat frame 1, and the rotating shaft 3 rotates in conjunction with the rotating sleeve 10. The rotating sleeve 10 can be made of a wear-resistant flexible material to prevent the rotating shaft 3 from directly rotating and rubbing against the seat frame 1, effectively reducing wear and reducing noise or abnormal sounds that may occur during the relative rotation process. In addition, in this embodiment, a washer 11 is welded and fixed to the backrest frame 2. The washer 11 is coaxially arranged with the rotating shaft 3. One side of the washer 11 is in contact with the backrest frame 2, and the other side is in contact with the rotating sleeve 10. The washer 11 is located between the seat frame 1 and the backrest frame 2, so that there is a certain distance between the seat frame 1 and the backrest frame 2. This avoids interference friction between the backrest frame 2 and the seat frame 1 during the rotation of the backrest frame 2 relative to the seat frame 1, making the unlocking action more stable and smooth.
[0034] In this embodiment, when unlocking is required, first follow Figure 1 The operating handle 12 in the prior art is pulled counterclockwise, and the operating handle 12 is rotated counterclockwise so that Figure 2 The pin 13 in the backrest is out of the slot 14, and the pin 13 no longer has a locking effect on the backrest frame 2. At this time, the backrest frame 2 can be manually pushed along the Figure 1 When the backrest frame 2 rotates clockwise, the shift fork 8 is driven to rotate clockwise through the rotating shaft 3, so that the shift fork 8 contacts the column 9 and applies a force to the column 9. The column 9 transmits the force of the shift fork 8 to the first movable plate 4, so that the first movable plate 4 rotates counterclockwise, further driving the second movable plate 5 to rotate counterclockwise, so that the second movable plate 5 finally pulls the zipper 7 to complete the unlocking action.
[0035] In this embodiment, since the shift fork 8 is directly fixed on the rotating shaft 3, when the backrest frame 2 rotates and drives the rotating shaft 3 to rotate, the rotating shaft 3 can stably drive the shift fork 8 to rotate, thereby utilizing the shift fork 8 to drive the column 9 to move and complete the subsequent unlocking action. The shift fork 8 is easy to install and has a stable structure, and can stably drive the unlocking process; at the same time, by providing the rotating sleeve 10 and the washer 11 structure, the smoothness and stability during the unlocking process are further improved, so that the unlocking action can be better completed.
[0036] A seat including the above-mentioned integrated motion control unlocking device; a car including the above-mentioned integrated motion control unlocking device or the aforementioned seat, so that the unlocking process is completed stably.
[0037] Example 2
[0038] The difference between the second embodiment and the first embodiment is that: Figure 5 As shown, in this embodiment, a limiting member is fixedly connected to the end of the column 9 away from the first movable plate 4, and a limiting space is enclosed between the limiting member and the first movable plate 4 to cooperate with the shift fork 8. Specifically, the limiting member is a retaining ring 15 welded to the end of the column 9. The retaining ring 15 is coaxially arranged with the column 9, and the diameter of the retaining ring 15 is larger than the diameter of the column 9, so that a limiting space is formed between the portion of the retaining ring 15 protruding from the side wall of the main body and the first movable plate 4. When the shift fork 8 rotates to contact the column 9 and applies a force to the column 9, the retaining ring 15 can play a role in limiting and stabilizing the shift fork 8, ensuring that the shift fork 8 drives the column 9 to move stably, thereby making unlocking more stable.
