Description

Technical Field

[0001] The present invention relates to the field of seat reversing, in particular to a mechanical transverse and longitudinal reversing seat frame assembly. Background Art

[0002] In order to adapt to the direction of train travel, traditional seats in a car have a mechanical manual reversing mechanism. For example, Patent No. CN205022594U discloses a seat rotation frame, which includes a base frame fixedly connected to the car, a turntable rotatably arranged with the base frame, and a slide slidably arranged with the turntable. The seat is set on the slide, and the slide is provided with an arc-shaped guide rail. The base frame is provided with a guide wheel that cooperates with the arc-shaped guide rail, and the base frame is provided with a locking mechanism between the turntable; when reversing, the locking mechanism is directly unlocked, and then the seat is rotated 180 degrees.

[0003] The above structure is not applicable in some scenarios. For example, there are two windshields spaced apart in the existing carriage, and multiple groups of seats are spaced apart between the two windshields. In order to arrange as many seats as possible, the distance between two adjacent groups of seats is small. If the seats are directly rotated during switching, there will be interference with the adjacent seats or windshields; and in order to adapt to the number of passengers more flexibly, it is often necessary to switch the seats between lateral (longitudinal) and transverse directions, but the switching device of the existing structure cannot meet this requirement, and a new seat switching device needs to be designed. Summary of the Invention

[0004] (1) Technical issues to be resolved

[0005] The problem to be solved by the present invention is to provide a mechanical transverse and longitudinal reversing seat frame assembly to overcome the defect that the existing seat reversing device cannot switch between transverse and longitudinal directions.

[0006] (2) Technical solution

[0007] In order to solve the above technical problems, the present invention provides a mechanical lateral and longitudinal reversing seat frame assembly, comprising:

[0008] A fixed skeleton assembly, comprising a fixed frame and a translation locking member provided at one end of the fixed frame;

[0009] A translation frame assembly, comprising a translation frame slidably mounted within the fixed frame, and a translation locking mechanism and a rotation locking mechanism provided at one end of the translation frame, wherein the translation locking mechanism is used to cooperate with the translation locking member to lock the translation frame assembly;

[0010] The rotating skeleton assembly comprises a rotating frame rotatably mounted at one end of the translation frame and a rotating limiting plate arranged on the rotating frame. The rotating limiting plate is used to cooperate with the rotating locking mechanism to lock the rotating skeleton assembly.

[0011] Furthermore, the translation locking mechanism includes a translation limiting hook plate corresponding to the translation locking member, the middle part of the translation limiting hook plate is hinged to the lower side of the translation frame, one end of the translation limiting hook plate is provided with a hook, and the other end is driven and connected to the rotation locking mechanism, and the translation locking member is provided with a limiting lever that can engage with the hook.

[0012] Furthermore, the rotation locking mechanism includes a stop pin rotatably mounted at one end of the translation frame, and the rotation limit plate is provided with a plurality of limit slots equidistantly spaced along the circumference thereof, adapted to mate with the stop pin. The rotation locking mechanism also includes a pedal hingedly connected to one end of the translation frame, with the stop pin disposed at the upper end of the pedal; a drive roller rotatably mounted on one side of the pedal, the drive roller abutting against the end of the translation limit hook plate. A first spring is installed between the pedal and the translation frame, the first spring constantly tending to move the stop pin toward the limit slots.

[0013] Furthermore, an auxiliary translation mechanism is provided at one end of the translation frame away from the translation locking mechanism. The auxiliary translation mechanism is used to drive the translation frame to slide outward after the translation locking mechanism is unlocked. The auxiliary translation mechanism includes a spring-limiting rod slidably mounted on the end of the translation frame, with a second spring mounted between the spring-limiting rod and the translation frame. The fixed frame is provided with a spring rod baffle at a position corresponding to the spring-limiting rod. When the translation frame slides toward the fixed frame, the spring-limiting rod abuts against the spring rod baffle, compressing the second spring and storing energy.

[0014] Furthermore, translation rails are symmetrically provided on both sides of the inner wall of the fixed frame, the translation frame is slidably connected to the fixed frame via the translation rails, and the rear end of the fixed frame is symmetrically provided with translation limit plugs for limiting the translation frame.

[0015] Furthermore, a center seat is provided at the center of the rotating frame, a rotating disk is installed on the center seat, and the rotating frame is rotatably connected to the translation frame through the rotating disk; the rotation limit disk is provided on the outside of the center seat, a first rotation limit block is provided on the center seat, and two second rotation limit blocks that cooperate with the first rotation limit block to limit the position are provided on the translation frame.

[0016] Furthermore, auxiliary support pads for supporting the rotating frame are symmetrically arranged on both sides of the upper end of the fixed frame, and a plurality of auxiliary support pads for supporting the rotating limit plate are arranged in a circular shape at equal intervals on the translation frame.

[0017] (3) Beneficial effects

[0018] The present invention provides a mechanical transverse and longitudinal reversing seat frame assembly, which cooperates with a translation frame component, a rotation frame component, a translation locking mechanism, a rotation locking mechanism and an auxiliary translation mechanism. When reversing, the translation limit hook plate is disengaged from the translation locking component by a foot pedal, and the translation frame component is unlocked. Driven by the auxiliary translation mechanism, the translation frame component slides toward the outside of the fixed frame component. At this time, when the rotation frame component is rotated, it will not interfere with the surrounding seats or windshields, ensuring the feasibility of the structure and adapting to the above-mentioned scenarios; then, the foot pedal disengages the stop pin from the current limit slot, and the rotation frame component is unlocked. Then, the rotation frame component is rotated 90 degrees, so that the stop pin is stuck in the next limit slot to lock the rotation frame assembly. It can switch between transverse and longitudinal directions, and can be switched to a reasonable state according to the number of passengers, so it is more flexible to use; it overcomes the defect that the existing seat reversing device cannot switch between transverse and longitudinal directions.

[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0033] See Figures 1 to 12 The present invention provides a mechanical transverse and longitudinal reversing seat frame assembly, comprising a fixed frame component 1, a translation frame component 2 and a rotation frame component 3.

[0034] See Figure 3 and Figure 4 The fixed frame assembly 1 includes a fixed frame 11 and a translation locking member 12 disposed at the outer end of the fixed frame 11. The outer end of the fixed frame 11 is provided with an opening to facilitate sliding the translation frame assembly 2 in and out. A mounting rod is provided at the outer end of the fixed frame assembly 1, and the translation locking member 12 is fixed in the middle position of the mounting rod.

[0035] See Figures 4 to 6The translational frame assembly 2 includes a translational frame 21 slidably mounted within the fixed frame 11, and a translational locking mechanism 22 and a rotational locking mechanism 23 disposed on the outer ends of the translational frame 21. The translational locking mechanism 22 cooperates with the translational locking member 12 to lock the translational frame assembly 2. Translational rails 14 are symmetrically disposed on both sides of the inner wall of the fixed frame 11, through which the translational frame 21 is slidably connected to the fixed frame 11. Translational limit plugs 15 are symmetrically disposed at the rear end of the fixed frame 11 to limit the position of the translational frame 21.

[0036] See Figure 8 、 Figure 10 and Figure 11 The translation locking mechanism 22 includes a translation limiting hook plate 221 corresponding to the translation locking member 12. The middle portion of the translation limiting hook plate 221 is hinged to the lower side of the translation frame 21. A hook 222 is provided at one end of the translation limiting hook plate 221, and its other end is drivingly connected to the rotation locking mechanism 23. The rotation locking mechanism 23 can drive the translation limiting hook plate 221 to lock or unlock the translation frame assembly 2. The translation locking member 12 is provided with a limiting lever 121 that can engage with the hook 222. When the hook 222 engages the limiting lever 121, the translation frame 21 is locked; when the hook 222 disengages the limiting lever 121, the translation frame 21 is unlocked.

[0037] See Figure 5 and Figure 7 The rotating skeleton assembly 3 includes a rotating frame 31 rotatably mounted at one end of the translation frame 21 and a rotation limit plate 32 disposed on the rotating frame 31. The rotation limit plate 32 is used to cooperate with the rotation locking mechanism 23 to lock the rotating skeleton assembly 3. A center seat 33 is provided at the center of the rotating frame 31, and a rotation plate 34 is mounted on the center seat 33. The rotating frame 31 is rotatably connected to the translation frame 21 via the rotation plate 34. The rotation limit plate 32 is disposed on the outer side of the center seat 33, and a first rotation limit block 35 is disposed on the center seat 33. The translation frame 21 is provided with two second rotation limit blocks 25 that cooperate with the first rotation limit blocks 35 to limit the position. The first rotation limit block 35 and the second rotation limit block 25 cooperate to control the rotation angle of the rotating frame 31.

[0038] See Figure 7 and Figure 9 The rotation locking mechanism 23 includes a stop pin 231 rotatably mounted at one end of the translation frame 21. A plurality of stop slots 321 are equidistantly spaced along the circumference of the rotation limit plate 32, which are adapted to fit within the stop pin 231. In this embodiment, there are three stop slots 321, with two on either side arranged at 180 degrees, and the middle stop slot 321 at 90 degrees to the two side stop slots 321, ensuring 90-degree rotation and thus enabling switching between horizontal and vertical orientations.

[0039] See Figure 6 、 Figure 11 and Figure 12 The rotation locking mechanism 23 also includes a pedal 232 hinged to one end of the translation frame 21, with a stop pin 231 positioned at the upper end of the pedal 232. A drive roller 233 is rotatably mounted on one side of the pedal 232, which abuts against the end of the translation limit hook plate 221. This arrangement allows unlocking both the translation locking mechanism 22 and the rotation locking mechanism 23 simply by stepping on the pedal 232, streamlining the operation steps and making it easier to operate. A first spring 234 is installed between the pedal 232 and the translation frame 21, constantly urging the stop pin 231 to move toward the limit slot 321.

[0040] See Figure 4 、 Figure 6 and Figure 8 An auxiliary translation mechanism 24 is provided at one end of the translation frame 21 away from the translation locking mechanism 22. The auxiliary translation mechanism 24 is used to drive the translation frame 21 to slide outward after the translation locking mechanism 22 is unlocked. The auxiliary translation mechanism 24 includes a spring limiting rod 241 slidably mounted on the end of the translation frame 21, and a second spring 242 is installed between the spring limiting rod 241 and the translation frame 21; the fixed frame 11 is provided with a spring rod baffle 13 at a position corresponding to the spring limiting rod 241. When the translation frame 21 slides toward the fixed frame 11, the spring limiting rod 241 abuts against the spring rod baffle 13, and the second spring 242 is compressed to store energy. In this way, by providing the auxiliary translation mechanism 24, the translation frame 21 can be automatically ejected outward after the translation locking mechanism 22 is unlocked, which is more labor-saving and convenient to operate.

[0041] See Figure 4 and Figure 5 The fixed frame 11 has symmetrical grooves on both sides of its upper end. Auxiliary support strips 4 are located at the bottom of the grooves to support the rotating frame 31. When the rotating frame 31 switches from a longitudinal to a transverse orientation, it falls into the grooves and rests on the auxiliary support strips 4, making the upper portion more stable and reducing wobbling. Multiple auxiliary support strips 4 are evenly spaced around the translation frame 21 to support the rotating limit plate 32, further reducing wobbling.

[0042] The use process of this seat frame assembly is as follows:

[0043] In the horizontal state: the rotating frame 31 and the fixed frame 11 are arranged vertically, the stop pin 231 is placed in the middle limit slot 321 to lock the rotating frame 31, and the hook 222 engages the limit lever 121 to lock the translation frame 21, and the auxiliary translation mechanism 24 is compressed to store energy.

[0044] When it is necessary to switch from the horizontal direction to the vertical direction, first step on the pedal 232, and the pedal 232 drives the translation limit hook plate 221 to rotate through the driving roller 233, so that the hook 222 is disengaged from the limit stop rod 121, and the translation frame 21 is unlocked; under the drive of the auxiliary translation mechanism 24, the translation frame 21 slides toward the outside of the fixed frame 11 and stops at the limit structure of the translation slide rail 14; then, step on the pedal 232 again, and the pedal 232 drives the stop pin 231 to rotate, and the stop pin 231 is aligned with the limit slot in the middle. 321 disengages and the rotating frame 31 is unlocked; then, the rotating frame 31 can be rotated to either side (±90 degrees left and right) so that the rotating frame 31 is parallel to the fixed frame 11, and the stop pin 231 engages with the limit slot 321 on either side, thereby re-locking the rotating frame 31, and finally the translation frame 21 is pushed back into the fixed frame 11, and the hook 222 engages the limit stop rod 121 to re-lock the translation frame 21, and the auxiliary translation mechanism 24 is re-compressed and stored energy for the next switching use.

[0045] The present embodiment provides a mechanical transverse and longitudinal reversing seat frame assembly, which is additionally provided with a translation frame component, a rotation frame component, a translation locking mechanism, a rotation locking mechanism and an auxiliary translation mechanism. When reversing, the translation limit hook plate is disengaged from the translation locking component by a foot pedal, and the translation frame component is unlocked. Driven by the auxiliary translation mechanism, the translation frame component slides toward the outside of the fixed frame component. At this time, when the rotation frame component is rotated, it will not interfere with the surrounding seats or windshields, ensuring the feasibility of the structure and adapting to the above-mentioned scenarios; then, the foot pedal disengages the stop pin from the current limit slot, unlocking the rotation frame component, and then the rotation frame component is rotated 90 degrees so that the stop pin is engaged in the next limit slot to lock the rotation frame component. It can switch between transverse and longitudinal directions, and can switch to a reasonable state according to the number of passengers; for example, when there are more passengers, it can be switched to the longitudinal state to reduce the space occupied by the seat; when there are fewer passengers, it can be switched to the transverse state, which is more flexible to use.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
