Description

Technical Field

[0001] This invention relates to the field of automotive seats, and more particularly to a vehicle table with a buffer and noise reduction structure arranged between the table shell and the internal frame. Background Technology

[0002] The current design of mainstream passenger car / commercial vehicle seatback tabletops lacks a proper tensioning structure between the outer shell and the internal frame when the tabletop is folded up. This can lead to internal collision noises when the tabletop is bumpy or pressed, affecting the driving and riding experience. There is an urgent need for a new connection structure between the outer shell and the internal frame of the vehicle tabletop. Summary of the Invention

[0003] In view of the above problems, the purpose of the present invention is to provide a vehicle table with a frame buffer structure, which arranges a buffer cap between the outer panel and the metal frame to prevent hard-surface collisions, thereby reducing the above-mentioned collision noises, improving the driving experience and sense of quality, and overcoming the shortcomings of the prior art.

[0004] This invention provides a vehicle table with a frame-based buffer structure, comprising: an outer frame, an inner frame snapped and fixed to the outer frame, a table metal support frame disposed between the outer and inner frames, an outer skin covering the outer frame, and a linkage flipping mechanism connecting the table metal support frame and the seat frame. The table metal support frame is fixed to the inner frame by multiple metal fastening screws. Multiple buffer caps are installed on the outer frame at positions corresponding to the ribs of the table metal support frame, with one end of each buffer cap fixed to the outer frame. The other end rests against the ribs of the metal support frame of the tabletop. The linkage flipping mechanism includes: a four-bar linkage consisting of a set of upper links and a set of lower links, a frame connecting seat, and a spring. The frame connecting seat is fixed to the seat frame. One end of the set of upper links and the set of lower links is hinged to the metal support frame of the tabletop, and the other end of the set of upper links and the set of lower links is hinged to the frame connecting seat. One end of the spring is fixed to the frame connecting seat, and the other end of the spring rests against the lower link after it is folded up. The spring is used to assist in opening the vehicle tabletop.

[0005] As a preferred embodiment of the present invention, the upper side of the inner panel frame is provided with a folding slot, and a buckle protrusion is provided on the seat back corresponding to the position of the folding slot. After the inner panel frame is folded up, the folding slot is engaged with the buckle protrusion.

[0006] As a preferred embodiment of the present invention, a slot is provided on the inner side of the outer plate frame, and a hook is provided on the inner plate frame at the position corresponding to the snap-fit ​​protrusion. The outer plate frame is snapped and fixed to the inner plate frame through the slot and the hook.

[0007] As a preferred embodiment of the present invention, the buffer cap is a rubber buffer cap.

[0008] The beneficial effects of the present invention are as follows: Compared with the existing table structure, by adding a buffer structure, the discomfort caused by abnormal noise generated by the collision between the shell and the internal metal frame under bumpy or pressing conditions can be prevented. In addition, the present application has the advantages of reasonable design, simple and compact structure, and suitability for the current trend of new energy vehicles requiring more comfort and convenience.

[0014] See Figure 1-3As shown, this embodiment provides a vehicle table with a frame buffer structure, including: an outer frame 1, an inner frame 2 that is snapped and fixed to the outer frame 1, a table metal support frame 3 disposed between the outer frame 1 and the inner frame 2, an outer panel skin 4 covering the outer frame 1, and a linkage flipping mechanism connecting the table metal support frame 3 and the seat frame. The table metal support frame 3 is fixed to the inner frame 2 by multiple metal fastening screws 5. Multiple buffer caps 6 are installed on the outer frame 1 at positions corresponding to the ribs of the table metal support frame 3, and one end of the buffer cap 6 is fixed in a fixing groove opened on the outer frame 1. The other end of the buffer cap 6 rests against the ribs of the metal support frame 3 of the table. The linkage flipping mechanism includes: a four-bar linkage consisting of a set of two upper links 7 and a set of two lower links 8, a frame connecting seat 9, and a spring 10. The frame connecting seat 9 is fixed to the seat frame. One end of the two upper links 7 and the two lower links 8 is hinged to the metal support frame 3 of the table, and the other end of the two upper links 7 and the two lower links 8 is hinged to the frame connecting seat 9. One end of the spring 10 is fixed to the frame connecting seat 9, and the other end of the spring 10 rests against the lower link 8 after it is folded up. The spring 10 is used to assist in opening the vehicle table. The upper side of the inner frame 2 is provided with a folding slot 11. Corresponding to the position of the folding slot 11, a buckle protrusion is provided on the seat back. After the inner frame 2 is folded up, the folding slot 11 engages with the buckle protrusion, completing the folding up of the table. The outer frame 1 has a slot on its inner side, and the inner frame 2 has a hook at the corresponding position of the snap-fit ​​protrusion. The outer frame 1 is snapped and fixed to the inner frame 2 through the slot and the hook.

[0015] Furthermore, in this embodiment, the buffer cap 6 is a rubber buffer cap.

[0016] Working principle: The outer frame 1 and inner frame 2 are quickly assembled by using a snap-fit ​​method with hooks and slots. The table metal support frame 3 is installed on the inner frame 2. Previously, the outer frame 1 and the table metal support frame 3 were not fixedly connected. In addition, because the snap-fit ​​method of the outer frame 1 and inner frame 2 requires a reserved installation tolerance, after the outer frame 1 and inner frame 2 are installed, internal collision noises are prone to occur when the vehicle is subjected to bumps or is pressed, affecting the driving experience. In this embodiment, multiple buffer caps 6 are installed on the outer frame 1 at the positions corresponding to the ribs of the table metal support frame 3. The buffer caps 6 are made of rubber, so that a stable connection is formed between the outer frame 1 and the table metal support frame 3. In addition, to ensure the stability of the table after it is folded up, a spring 10 is added to support the four-link linkage after folding up, so that the folded table will not make any abnormal noise during launch turbulence. Moreover, the spring 10 can also assist in opening the table. Specifically, when opening the table, the buckle protrusion on the seat back needs to be pressed to separate the folding slot 11 from the buckle protrusion. Since no gap is reserved between the folding slot 11 and the buckle protrusion to ensure that the folded table will not make any abnormal noise during launch turbulence, the hand cannot reach into the folding slot 11 during the opening process. However, the added spring 10 can help push the four-link linkage, thereby causing the inner plate frame 2 to open up the gap that the hand can reach into.

[0017] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
