[0039] The locomotive with a dual-purpose sitting and lying passenger seat provided by the present disclosure provides a light and simple dual-purpose sitting and lying passenger seat for the driver's cab, which is mainly suitable for the sitting and lying needs of the passengers in the locomotive driver's cab. The light and simple dual-purpose sitting and lying passenger seat can be divided into three states, namely Figure 1 The state of leaning against the wall is shown, Figure 2 The seat status shown, such as Figure 3 The lying bed state shown; the seat does not occupy the effective space in the driver's cab when it is against the wall; in the seat adding state, it is used as a seat, the first seat and the second seat are pulled apart respectively, and the seat surfaces are directly lowered to use as seats; in the lying bed state, it is used as a bed, the first seat and the second seat are pulled apart respectively, the double-layer folding seat is unfolded to lay flat the seat surface, the first leg 13 and the second leg 23 are opened vertically to the ground, and the first leg 13 and the second leg 23 are in contact with the floor, and then the seat is pulled apart to lay flat the seat surface and used as a bed; it does not occupy the space in the driver's cab and is easy to operate, which can meet the needs of sitting or lying down for rest, improves the driver's comfort, and provides a convenient, temporary rest seat for drivers and passengers, so as to create a locomotive driver's cab environment to improve the health and safety of drivers, enhance the work efficiency and happiness of drivers, and improve the service quality and efficiency of the transportation industry.

[0040] Specifically, when the first seat is in a state of leaning against a wall, the first seat plate 11 is pivotally connected to the box wall through the first mounting seat 14 to improve the stability of the rotational connection between the first seat plate 11 and the box wall.

[0041] Among them, a first positioning pin 15 can be provided on the first mounting seat 14. When the first seat is in a wall-resting state, the first positioning pin 15 is simultaneously inserted into the mounting hole of the first mounting seat 14 and the pin hole of the rotating part of the first seat plate 11, thereby fixing the first seat plate 11 relative to the first mounting seat 14.

[0042] The first seat plate 11 can be pivotally connected to the box wall via two first mounting seats 14 to enhance the stability of the rotational connection between the first seat plate 11 and the box wall; the first positioning pin 15 can be disposed on only one of the first mounting seats 14 , or both first mounting seats 14 can be provided with the first positioning pin 15 .

[0043] Specifically, when the second seat is in a state of leaning against the wall, the third seat plate 21 is pivotally connected to the box wall through the second mounting seat 24 to improve the stability of the rotational connection between the third seat plate 21 and the box wall.

[0044] Among them, a third positioning pin 25 can be provided on the second mounting seat 24. When the third seat is in a wall-resting state, the third positioning pin 25 is simultaneously inserted into the mounting hole of the second mounting seat 24 and the pin hole of the rotating part of the third seat plate 21, thereby fixing the third seat plate 21 relative to the first mounting seat 14.

[0045] Among them, the third seat plate 21 can be pivotally connected to the box wall through two second mounting seats 24 to improve the stability of the rotational connection between the third seat plate 21 and the box wall; the third positioning pin 25 can be only set on one of the second mounting seats 24, or the third positioning pin 25 can be set on both second mounting seats 24.

[0046] Specifically, when the first seat is in the seat state, the first seat as a whole is directly connected to the box body through the rotation of the first seat plate 11 to achieve the state adjustment of the first seat.

[0047] When the first seat is in the seat state, the first positioning pin 15 is simultaneously inserted into the mounting hole of the first mounting seat 14 and another pin hole of the rotating part of the first seat plate 11 to fix the first seat plate 11 relative to the first mounting seat 14 in the seat state.

[0048] Specifically, when the second seat is in the seat state, the second seat as a whole is directly connected to the box body through the rotation of the third seat plate 21 to achieve the state adjustment of the second seat.

[0049] When the second seat is in the seat state, the third positioning pin 25 is simultaneously inserted into the mounting hole of the second mounting seat 24 and another pin hole of the rotating part of the third seat plate 21 to fix the third seat plate 21 relative to the second mounting seat 24 in the seat state.

[0050] Specifically, when the first seat needs to be in a lying state, such as Figure 5 As shown, the second seat plate 12 can be rotated first to be in an unfolded state relative to the first seat plate 11; Figure 6 As shown, the first leg 13 is then rotated so that it is in a vertical or substantially vertical state with the second seat plate 12; Figure 7 As shown, the first seat plate 11 is then rotated relative to the box wall to achieve the purpose of unfolding the first seat plate 11 and the second seat plate 12 of the first seat, so that it is in a lying state.

[0051] The second seat plate 12 and the first seat plate 11 can be rotatably connected via hinges.

[0052] When the first seat plate 11 and the second seat plate 12 are in the locked and retracted state, the second positioning pin 16 can be used to fasten the first seat plate 11 and the second seat plate 12 together to prevent the first seat plate 11 and the second seat plate 12 from being separated, thereby improving the reliability of the connection between the first seat plate 11 and the second seat plate 12.

[0053] The length of the first leg 13 is adjustable. Figure 7 As shown, the first leg 13 may include a leg body 131, and the leg body 131 includes a mother rod 1311 and a child rod 1312, and the mother rod 1311 and the child rod 1312 are telescopically connected; through the connection between the mother rod 1311 and the child rod 1312, the length of the first leg 13 can be adjusted.

[0054] Among them, a fixing piece 134 may be provided on the first leg 13. Through the fixing piece 134, after the mother rod 1311 and the sub-rod 1312 are adjusted to a preset position, the mother rod 1311 and the sub-rod 1312 are fixed together to avoid relative movement between the mother rod 1311 and the sub-rod 1312.

[0055] Among them, a locking bead can be set on the sub-rod 1312, and a locking hole can be set on the mother rod 1311. After the sub-rod 1312 is pulled out from the mother rod 1311 to a preset position, the locking column is wedged into the locking hole to achieve the length positioning between the sub-rod 1312 and the mother rod 1311.

[0056] Specifically, when the second seat plate 12 and the first leg 13 are in the retracted state, the first leg 13 is located between the first seat plate 11 and the second seat plate 12 ; by locating the first leg 13 between the first seat plate 11 and the second seat plate 12 , the first leg 13 is hidden.

[0057] When the second seat plate 12 and the first leg 13 are in the retracted state, a first accommodation space is formed between the first seat plate 11 and the second seat plate 12, the first seat plate 11 and the second seat plate 12 are in contact with each other in a circle in the circumferential direction, and the first leg 13 is located in the first accommodation space. With the first leg 13 located in the first accommodation space, the first seat plate 11 and the second seat plate 12 are in contact with each other in a circle in the circumferential direction, thereby improving the stability of the first seat plate 11 and the second seat plate 12.

[0058] Specifically, when the second seat needs to be in a lying state, such as Figure 5 As shown, the fourth seat plate 22 can be rotated first to be in an unfolded state relative to the third seat plate 21; Figure 6 As shown, the second leg 23 is then rotated so that it is in a vertical or substantially vertical state with the fourth seat plate 22; the third seat plate 21 is then rotated relative to the box wall to achieve the purpose of unfolding the third seat plate 21 and the fourth seat plate 22 of the second seat, so that it is in a lying bed state.

[0059] The fourth seat plate 22 and the third seat plate 21 can be rotatably connected via hinges.

[0060] Among them, when the third seat plate 21 and the fourth seat plate 22 are in the locked and retracted state, the third seat plate 21 and the fourth seat plate 22 can be fastened together by the fourth positioning pin 26 to prevent the third seat plate 21 and the fourth seat plate 22 from separating, thereby improving the reliability of the connection between the third seat plate 21 and the fourth seat plate 22.

[0061] The length of the second leg 23 is adjustable. The second leg 23 includes a leg body, which includes a mother rod and a child rod, and the mother rod and the child rod are telescopically sleeved; the length of the second leg 23 is adjusted by the sleeve connection between the mother rod and the child rod.

[0062] Specifically, when the fourth seat plate 22 and the second leg 23 are in the retracted state, the second leg 23 is located between the third seat plate 21 and the fourth seat plate 22 ; by locating the second leg 23 between the third seat plate 21 and the fourth seat plate 22 , the second leg 23 is hidden.

[0063] When the fourth seat plate 22 and the second leg 23 are in the retracted state, a second accommodation space is formed between the third seat plate 21 and the fourth seat plate 22, the third seat plate 21 and the fourth seat plate 22 are in contact with each other in a circle in the circumferential direction, and the second leg 23 is located in the second accommodation space. Since the second leg 23 is located in the second accommodation space, the third seat plate 21 and the fourth seat plate 22 are in contact with each other in a circle in the circumferential direction, thereby improving the stability of the third seat plate 21 and the fourth seat plate 22.

[0064] Specifically, Figure 3 As shown, a first hydraulic rod is connected between the first leg 13 and the second seat plate 12 , and the first hydraulic rod is used to improve the reliability of the rotation between the first leg 13 and the second seat plate 12 .

[0065] The first hydraulic rod may also be replaced by a telescopic rod to improve the reliability of the connection between the first support and the second seat plate 12 .

[0066] Specifically, Figure 3 As shown, a second hydraulic rod is connected between the second supporting leg 23 and the fourth seat plate 22, and the second hydraulic rod is used to improve the reliability of the rotation between the second supporting leg 23 and the fourth seat plate 22.

[0067] The second hydraulic rod may also be replaced by a telescopic rod to improve the reliability of the connection between the second support and the fourth seat plate 22 .

[0068] Specifically, Figure 3 As shown, the first leg 13 is connected to the side of the second seat plate 12 away from the rotational connection with the first seat plate 11 to enhance the supporting stability of the first leg 13 on the second seat plate 12; at the same time, it is convenient for the first leg 13 to be stored after being folded.

[0069] The first supporting leg 13 is pivotally connected to the second seat plate 12 .

[0070] Specifically, Figure 3 As shown, the second leg 23 is connected to the side of the fourth seat plate 22 away from the rotational connection with the third seat plate 21 to enhance the supporting stability of the second leg 23 on the fourth seat plate 22; at the same time, it is convenient for the second leg 23 to be stored after being folded.

[0071] The second supporting leg 23 is pivotally connected to the fourth seat plate 22 .

[0072] Specifically, a first support foot 133 is provided at the position where the first support leg 13 contacts the ground. The first support foot 133 may be an adjustable foot cup, and the length of the first support leg 13 may be adjusted by rotating so as to contact the ground.

[0073] A second foot is provided at the position where the second leg 23 contacts the ground. The second foot may be an adjustable foot cup, and the length of the second leg 23 can be adjusted by rotating it so that it contacts the ground.

[0074] It should be noted that the switching between the above-mentioned wall-leaning state, seat state, and bed-lying state is a one-way process, and the switching between the bed-lying state, seat state, and wall-leaning state is the reverse operation process of the above-mentioned process, which will not be repeated here.

[0075] Specifically, Figure 3 to Figure 6 As shown, when the first seat panel 11, the second seat panel 12, the third seat panel 21 and the fourth seat panel 22 are all in the unfolded state, and the first leg 13 and the second leg 23 are both supported on the bottom of the box, the second seat panel 12 and the fourth seat panel 22 are arranged adjacent to each other. By arranging the second seat panel 12 and the fourth seat panel 22 adjacent to each other, the first seat panel 11, the second seat panel 12, the third seat panel 21 and the fourth seat panel 22 can form a seat surface that is continuously spliced ​​together, thereby improving the comfort of lying down.

[0076] Among them, in the length direction of the car body, the gap between the second seat plate 12 and the fourth seat plate 22 is less than or equal to five centimeters, for example, five centimeters, four centimeters, three centimeters, two centimeters, one centimeter, or the second seat plate 12 and the fourth seat plate 22 are directly abutted together, and the present disclosure does not impose any restrictions on this.

[0077] Specifically, Figure 3 and Figure 4As shown, when the first seat panel 11, the second seat panel 12, the third seat panel 21 and the fourth seat panel 22 are all in the unfolded state, and the first leg 13 and the second leg 23 are all supported on the bottom of the box, the first seat panel 11, the second seat panel 12, the third seat panel 21 and the fourth seat panel 22 are at the same height relative to the bottom of the box. By making the first seat panel 11, the second seat panel 12, the third seat panel 21 and the fourth seat panel 22 at the same height relative to the bottom of the box, the seat surface formed by the first seat panel 11, the second seat panel 12, the third seat panel 21 and the fourth seat panel 22 is arranged parallel to the bottom of the box, which can improve the comfort of lying down.

[0078] In some embodiments, a first elastic member is connected between the first seat plate 11 and the box wall. When the first seat plate 11 rotates from a stowed state toward an expanded state, the tensile force of the first elastic member first gradually increases and then gradually decreases. That is, when the first seat plate 11 rotates from a stowed state toward an expanded state, the elastic resistance first increases and then decreases, and when it rotates from an expanded state toward a stowed state, the elastic resistance also first increases and then decreases.

[0079] In some embodiments, a second elastic member is connected between the third seat plate 21 and the box wall. When the third seat plate 21 rotates from a retracted state to an expanded state, the tensile force of the second elastic member first gradually increases and then gradually decreases. That is, when the second seat plate 12 rotates from a retracted state to an expanded state, the elastic resistance first increases and then decreases, and when it rotates from an expanded state to a retracted state, the elastic resistance first increases and then decreases.

[0080] In some embodiments, the first seat plate 11, the second seat plate 12, the third seat plate 21 and the fourth seat plate 22 may all be of the same composition, with the upper portion being a seat cushion composed of polyvinyl chloride seat leather and polyurethane high-resilience foam, and the lower portion being a stainless steel structural frame.

[0081] Among them, the exposed parts of the frame of the lightweight and simple sitting and lying seat are galvanized.

[0082] In some embodiments, the lightweight and simple dual-purpose sitting and lying seat adopts a symmetrical design on both sides. The rotating folding part is 442mm and the seat folding part weighs 12.5kg. The seat is labor-saving and convenient to use when folded and unfolded. The length × width of the first seat and the second seat when unfolded into a bed is 1800mm × 460mm, which meets the requirements of human height and body width.

[0083] Among them, the lightweight and simple sitting and lying dual-purpose passenger seat should be able to withstand a weight of 150kg in the vertical direction. The seat surface and filling (cushion material, support, mounting base, frame and bottom plate, etc.) should have reliable structural strength and should not be damaged, permanently deformed or welded under this load.

[0084] Among them, the lightweight and simple sitting and lying dual-purpose passenger seat is installed on the rear wall of the driver's cab with 4-M10 bolts. It is firmly installed and flexibly positioned to prevent it from loosening due to sudden speed changes. It can withstand the impact and vibration generated during the normal operation of the locomotive. Its vibration frequency and vibration acceleration are within the range listed in GB / T21563.

[0085] In some embodiments, the lightweight and simple dual-purpose sitting and lying seat is locked by a positioning pin when it is against the wall; when used as a seat, the positioning pin can be pulled out and the seat can be rotated to be laid down; when folded up, the seat can be directly rotated until the positioning pin returns to its original position. When used as a bed, the positioning pin is opened, the handle is pressed, and the second seat plate 12 is rotated and unfolded; the legs are pulled to unfold the lower legs; the first seat plate 11 and the second seat plate 12 are rotated as a whole until the first leg 13 touches the ground, and the adjustment foot cup of the first leg 13 is adjusted until the seat surface is parallel to the ground; the opening method of the third seat plate 21 and the fourth seat plate 22 is similar to the opening method of the first seat plate 11 and the second seat plate 12; when folding the seat, the lower leg must be rotated first until the lower leg card is wedged into the upper leg card slot, and the rest is the reverse process of opening.
