Description

Technical Field

[0001] The invention relates to a novel train sleeper seat conversion vehicle and method, belonging to the technical field of train equipment. Background Art

[0002] With the rapid economic development of my country, the railway industry has ushered in a new leap-forward development, and people's willingness to go out and take the train has gradually increased. The berth and the seat are the direct interface of the passenger. At present, the train seats and berths exist separately and belong to different carriages. The berth is suitable for long-term sleeping, but if you want to sit and rest during the day, the berth is not so comfortable. If the berth can be converted into a seat form, and the conversion method is quick and easy, it is indeed a good choice. For example, the applicant's patent CN202010562569.2, the name of a new type of berth-chair conversion train vehicle and its use method, can be used as a berth for passengers during the day, and can be converted into a berth at night, but this invention is only a conversion between berths and seats, without a tea table, and later upgraded and optimized the applicant's patent CN202122945938.9, the name of a new type of convertible berth for trains, this invention adds a tea table function, but after the berth is converted into a seat, the tea table and the wall need to be connected and fixed, the tea table area is too large and the structural stability is poor, and the conversion between seats and berths is relatively complicated. In order to solve this problem, the following invention is further made. Summary of the invention

[0003] The purpose of the present invention is to provide a sleeper seat conversion vehicle and method for trains, the sleeper seat conversion method is quick and simple, the tea table structure is stable, and the above-mentioned technical problems existing in the background technology are solved.

[0004] The technical solution of the present invention is: A new type of convertible vehicle for train sleeping berths and seats, comprising a backrest, a fixed berth, and a movable berth; the backrest is fixedly connected to the partition wall panel of the train, the fixed berth is located below the backrest, and the fixed berth is fixedly connected to the partition wall panel and the floor of the train. The backrest and the fixed berth form a set of seats, and the movable berth is located between two sets of seats arranged opposite to each other; the movable berth includes a bracket, a first berth body, a second berth body, a tea table, a first connecting rod, a second connecting rod, and a connecting angle iron; the bracket of the movable berth is fixedly connected to the side wall panel of the train, and a support shaft is provided on the bracket. A slideway is provided at one end of the side surface of the first berth body close to the bracket, and the support shaft of the bracket is embedded in the slideway of the first berth body. The first berth body can rotate around the support shaft and slide along the length direction of the slideway; one end of the side surface of the first berth body far from the bracket is hinged to one end of the side surface of the second berth body close to the first berth body through the first connecting rod and the second connecting rod. The first connecting rod and the second connecting rod are parallel to each other and together with the first berth body and the second berth body form a four-bar mechanism; the tea table is fixedly connected to one end of the second berth body far from the first berth body through the connecting angle iron, and the support shaft is perpendicular to the second berth body; the second berth body and the first berth body can be stacked together or unfolded into a plane through the four-bar mechanism; after the second berth body and the first berth body are stacked and then rotated 90° along the support shaft of the bracket, and the support shaft slides in the slideway of the first berth body at the same time, the tea table is in a horizontal state, and the movable berth becomes a tea table structure; performing the opposite operation, the second berth body and the first berth body are unfolded into a plane, and the side surface of the tea table contacts the bottom plate to play a supporting role. The movable berth is flush with the fixed berths on both sides to form a complete sleeping surface together, and together they form a sleeping berth structure.

[0005] Further, four-bar mechanisms are provided on both sides of the second berth body and the first berth body.

[0006] Further, the length of the first berth body is greater than the length of the second berth body.

[0007] Further, the bracket is composed of a bottom surface, a first vertical surface, and a second vertical surface to form a U-shaped integral structure. The first vertical surface and the second vertical surface are parallel to each other and are respectively perpendicular to both sides of the bottom surface. An installation hole is provided on the second vertical surface and is fixedly connected to the side wall panel of the train through screws. A raised plate higher than the bottom surface is provided at a position on the bottom surface close to the first vertical surface, and a support shaft is provided on the raised plate. The support shaft matches the slideway on the side surface of the first berth body. The bottom surface and the first vertical surface together restrain or support the first berth body. The distance between the first vertical surface and the second vertical surface is equal to the sum of the thicknesses of the first berth body and the second berth body. When the movable berth becomes a tea table structure, the right angle between the bottom surface and the first vertical surface buckles on the first berth body to play a restraining role. When the movable berth becomes a sleeping berth structure, a right angle is formed between the raised plate of the bottom surface and the first vertical surface, and the first vertical surface assists in supporting the first berth body.

[0008] Further, when the support shaft is located at the outermost end of the slideway, the remaining length of the side surface of the first berth body outside the slideway is less than the distance between the first vertical surface and the second vertical surface, which is convenient for stacking the first berth body and the second berth body.

[0009] Furthermore, the height of the first facade is greater than that of the second facade.

[0010] A method of using a new type of train sleeper seat conversion device. The movable bed realizes two structures through the four-bar mechanism, slideway and bracket: the second bed body and the first bed body are stacked together or unfolded into a plane; after the second bed body and the first bed body are stacked, they are rotated 90° along the support shaft of the bracket, and the support shaft slides in the slideway of the first bed body at the same time. The tea table is in a horizontal state, and the movable bed becomes a tea table structure; when the second bed body and the first bed body are unfolded into a plane, the side of the tea table contacts the bottom plate to play a supporting role, and the movable bed and the fixed bed form a complete sleeping surface together to constitute a sleeper structure.

[0011] The beneficial effects of the present invention are: simple and reliable structure, quick and convenient conversion method between bed and chair, and stable tea table structure. BRIEF DESCRIPTION OF THE DRAWINGS
