[0027] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the embodiments and the accompanying drawings.

[0028] See also Figure 1 The subway train 100 of the utility model includes an integrated lifting handrail 10 for holding and leaning, a front part 20, a car 30 and an advertising projector 40. The integrated lifting handrail 10 for holding and leaning is installed in the car 30, and the car 30 provides an installation place and a support function for the integrated lifting handrail 10 for holding and leaning. The car 30 is connected to the front part 20 to meet the need of the front part 20 to pull the car 30 to move together. The advertising projector 40 is installed on the car 30, and the car 30 provides an installation place for the advertising projector 40. The advertising projector 40 is configured to project advertising information on the car 30, so that advertising information can be projected on the car 30 when the train stops. It should be noted that although Figure 1 The carriage 30 is shown to be equipped with an advertising projector 40. Obviously, the advertising projector 40 may be deleted according to actual needs. Figure 1 Limits shown.

[0029] Recombination Figures 2 to 4 As an example, the grip-and-lean integrated lifting armrest 10 includes a hollow first fixed frame 11, a second fixed frame 12 which is arranged side by side and is spaced apart from the first fixed frame 11 in the horizontal direction and is hollow, a gantry lifting frame 13, a leaning body 14, a lifting motor 15, a horizontal rotating shaft 16, a lifting rack 17 respectively located in the first fixed frame 11 and the second fixed frame 12, and a transmission gear 18 meshing with the lifting rack 17.

[0030] The gantry lifting frame 13 includes a first side leg 131, a second side leg 132, and a crossbeam 133 connected to the first side leg 131 and the second side leg 132 for holding. Figure 6 As an example, the first fixed stand 11 and the second fixed stand 12 are parallel to each other, the first side foot 131 and the second side foot 132 are parallel to each other, and the parallel direction of the first fixed stand 11 and the second fixed stand 12 is the same as the length direction of the cross beam 133, that is, the direction indicated by arrow A and the opposite direction. This design enables the gantry lifting frame 13 to perform vertical lifting movement. The leaning body 14 is located below the cross beam 133, so that there is a required gap between the leaning body 14 and the cross beam 133, thereby meeting the user's need to hold the cross beam 133; the leaning body 14 is also fixedly connected to the first side foot 131 and the second side foot 132 respectively, so as to meet the need of fixing the leaning body 14 to the gantry lifting frame 13 from both sides.

[0031] At the same time, the first side foot 131 is located in the first fixed frame 11 and is slidably connected to the first fixed frame 11 up and down to meet the need of the first side foot 131 sliding up and down along the first fixed frame 11; the lifting rack 17 in the first fixed frame 11 is also fixed on the first side foot 131 and extends downward from the first fixed frame 11 to meet the need of the lifting rack 17 in the first fixed frame 11 to mesh with the corresponding transmission gear 18; the second side foot 132 is located in the second fixed frame 12 and is slidably connected to the second fixed frame 12 up and down to meet the need of the second side foot 132 sliding up and down along the second fixed frame 12; the lifting rack 17 in the second fixed frame 12 is also fixed on the second side foot 132 and extends downward from the second fixed frame 12 to meet the need of the lifting rack 17 in the second fixed frame 12 to mesh with the corresponding transmission gear 18.

[0032] Furthermore, the horizontal shaft 16 is located directly below the first fixed stand 11 and the second fixed stand 12, the transmission gears 18 are respectively fixed to the two ends of the horizontal shaft 16, and the lifting motor 15 is located beside the horizontal shaft 16 and drives the horizontal shaft 16 to rotate; therefore, during the rotation of the horizontal shaft 16, the transmission gears 18 at the two ends of the horizontal shaft 16 drive the corresponding lifting rack 17 to rise and fall, thereby realizing the synchronous driving of the first side foot 131 and the second side foot 132 of the gantry lifting frame 13, thereby achieving the purpose of synchronous lifting of the two sides of the gantry lifting frame 13. Specifically, Figure 2 , Figure 3 , Figure 4 and Figure 6 As an example, the lifting motor 15 is located directly below the horizontal shaft 16, and the output shaft 151 of the lifting motor 15 extends upward toward the horizontal shaft 16. A first bevel gear 152 is fixed to the output shaft 151 of the lifting motor 15, and a second bevel gear 161 meshing with the first bevel gear 152 is fixed to the horizontal shaft 16. This design allows the lifting motor 15 to be buried in the carriage 30, avoiding the lifting motor 15 being convexly arranged in the carriage 30. At the same time, with the cooperation of the first bevel gear 152 and the second bevel gear 161, the transmission requirement of the output end 151 of the lifting motor 15 and the horizontal shaft 16 being arranged in a "cross" shape is met. More specifically, as follows:

[0033] like Figure 6 As shown, as an example, the output shaft 151 of the lifting motor 15 vertically bisects the horizontal rotating shaft 16, so that the lifting motor 15 drives the middle position of the horizontal rotating shaft 16 to ensure the uniformity of the force on the horizontal rotating shaft 16; in addition, the second bevel gear 161 is larger than the first bevel gear 152, that is, the wheel diameter of the second bevel gear 161 is larger than the wheel diameter of the first bevel gear 152. This design can reduce the output speed of the lifting motor 15, so that the horizontal rotating shaft 16 obtains a larger torque output, thereby more effectively driving the gantry lifting frame 13 to rise and fall together with the leaning body 14.

[0034] like Figures 1 to 6 As shown, as an example, the one-piece lifting armrest 10 for holding and leaning further includes a horizontal fixing seat 19, a first fixing frame 11 passes downward through one end 191 of the horizontal fixing seat 19 and is fixedly connected to the one end 191, and a second fixing frame 12 passes downward through the other end 192 of the horizontal fixing seat 19 and is fixedly connected to the other end 192; with the help of the fixed connection between the horizontal fixing seat 19 and the carriage 30, the purpose of assembling the one-piece lifting armrest 10 for holding and leaning 10 in the carriage 30 is achieved, thereby improving the reliability of assembling the one-piece lifting armrest 10 for holding and leaning 10 in the carriage 30; obviously, according to actual needs, the horizontal fixing seat 19 can also be deleted, so it is not used as Figures 1 to 6When the horizontal fixing seat 19 is deleted, the first fixing frame 11 and the second fixing frame 12 are fixed to the carriage 30; when the one-piece lifting armrest 10 further includes the horizontal fixing seat 19, the horizontal shaft 16, the lifting motor 15 and the transmission gear 18 are each located below the horizontal fixing seat 19, for example but not limited to Figure 5 Shown directly below.

[0035] like Figures 2 to 4 As shown in the figure, as an example, the first side leg 131, the second side leg 131, the first fixed stand 11 and the second fixed stand 12 are all flat structures, so as to effectively reduce the space occupied by the integrated lifting armrest 10 in the carriage 30. In addition, the lifting rack 17 on the first side leg 131 is located on one side of the first side leg 131 (for example, the side of the first side leg 131) in the width direction of the first side leg 131 (i.e., the direction indicated by arrow B and the opposite direction). Figure 3 and Figure 4 The lifting rack 17 on the first side foot 131 does not occupy the gap between the first side foot 131 and the first fixed stand 11, so the first side foot 131 and the first fixed stand 11 are more compact. In addition, the lifting rack 17 on the second side foot 132 is located on one side of the second side foot 132 (for example, Figure 3 and Figure 4 The lifting rack 17 on the second side foot 132 does not occupy the gap between the second side foot 132 and the second fixed stand 12, so the second side foot 132 and the second fixed stand 12 are more compact. Figure 3 and Figure 4 As an example, the cross-sectional outer contours of the first fixed stand 11, the second fixed stand 12, the first side leg 131 and the second side leg 132 are all rectangular with rounded corners. Of course, they can also be elliptical, so it is not necessary to use Figure 3 and Figure 4 Limits shown.

[0036] like Figures 2 to 4 As shown in FIG. 1 , as an example, the leaning body 14 includes a soft bag 141, a door-shaped frame 142 respectively fixedly connected to the first side leg 131 and the second side leg 132, and an inclined frame 143 extending downwardly from the ends of the opposite sides of the door-shaped frame 142 in a direction away from the door-shaped frame 142. The inclined frame 143 also protrudes from the first side leg 131 and the second side leg 132. The soft bag 141 is respectively fixed at the position where the door-shaped frame 142 and the inclined frame 143 define a corner 144. Figure 5As shown; this design allows the leaning body 14 to provide a leaning function for the user from both sides, increasing the leaning position; in addition, with the cooperation of the door-shaped frame 142 and the inclined frame 143, the weight and material usage of the leaning body 14 can be reduced; in addition, with the soft bag 141, the comfort of the leaning body 14 is improved. Specifically, Figure 5 As an example, the inclined frames 143 at the ends of the door-shaped frame 142 on both sides are arranged in an "eight" shape to facilitate the manufacture of the leaning body 14.

[0037] Combination Figure 5 , Figure 7 and Figure 8 The working principle of the integrated lifting armrest 10 of the present invention is described as follows: Figure 5 The status shown is adjusted to Figure 7 In the state shown, at this time, the lifting motor 15 is rotated forward, and the forward-rotating lifting motor 15 drives the horizontal shaft 16 to rotate through the first bevel gear 152 and the second bevel gear 161, and the rotating horizontal shaft 16 drives the gantry lifting frame 13 and the leaning body 14 to descend downward together through the transmission gears 18 at both ends thereof and the lifting rack 17 corresponding to the transmission gear 18, until they descend to Figure 7 Status shown.

[0038] When you want to Figure 7 The status shown is adjusted to Figure 8 In the state shown, at this time, the lifting motor 15 is reversed, and the reversed lifting motor 15 drives the horizontal shaft 16 to rotate through the first bevel gear 152 and the second bevel gear 161, and the rotating horizontal shaft 16 drives the gantry lifting frame 13 and the leaning body 14 to rise together through the transmission gears 18 at both ends thereof and the lifting rack 17 corresponding to the transmission gear 18, until it rises to Figure 8 Status shown.

[0039] It should be noted that the above-mentioned forward rotation of the lifting motor 15 to achieve the lowering of the gantry lifting frame 13 and the reverse rotation to achieve the raising of the gantry lifting frame 13 are only for illustration. Obviously, according to actual needs, the gantry lifting frame 13 can also be raised when the lifting motor 15 rotates forward and lowered when the gantry lifting frame 13 is reversed.

[0040] Compared with the prior art, since the crossbeam 133 of the gantry lifting frame 13 is used for holding and the leaning body 14 is used for leaning, the holding and leaning functions are integrated; and since the lifting motor 15 can drive the two sides of the gantry lifting frame 13 to do synchronous lifting and lowering with the help of the horizontal rotating shaft 16, the lifting rack 17 and the transmission gear 18, thereby driving the leaning body 14 to do synchronous lifting and lowering, the use of holding and leaning can meet the needs of users of different heights. More importantly, with the help of the horizontal rotating shaft 16, the lifting rack 17 and the transmission gear 18, the same lifting motor 15 can drive the two sides of the gantry lifting frame 13 to do synchronous lifting and lowering, thereby reducing the number of lifting motors 15 used, and making the synchronous lifting of the two sides of the gantry lifting frame 13 better.

[0041] The above disclosure is only a preferred example of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
