In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.
[0027] As Figs. 1 to 4 As shown in the figure, the application provides a trolley with automatic braking function, the trolley 1 can move along the track, comprising resistance generating structure and mounting rack 3, the resistance generating structure 2 comprises magnetic field generating structure 2 and brake piece, and one of the magnetic field generating structure 2 and brake piece is connected on the trolley 1 through the mounting rack 3, and the other is connected on the track;The trolley 1 is also connected with reset assembly 4, and the reset assembly 4 comprises reset handle 41;One end of the mounting rack 3 is rotatably connected on the trolley 1, one end of the reset handle 41 is also rotatably connected on the trolley 1, and the reset handle 41 can drive the mounting rack 3 to rotate.
[0028] The application can automatically slow down or brake the trolley at specific positions of the track through the resistance generating structure, thereby improving the safety during use of the trolley; the magnetic field generating structure 2 and the brake cooperate to generate a force in the opposite direction of the movement direction through cutting of the magnetic induction lines, thereby achieving the effect of slowing down and braking the trolley; and the magnetic field generating structure 2 and the brake do not contact during the slowing down and braking process, thereby avoiding friction loss and prolonging the service life of the resistance generating structure; the reset assembly 4 is used to control the position of the magnetic field generating structure 2 or the brake, and the magnetic field generating structure 2 or the brake can be retracted when slowing down and braking is not needed, thereby avoiding affecting the normal operation of the trolley.
[0029] In the embodiment, the cost of the magnetic field generating structure 2 is higher than that of the brake, so the magnetic field generating structure 2 is connected to the reset assembly 4, and the brake is installed at the positions of the track where slowing down or braking is needed, thereby automatically slowing down the trolley 1 when slowing down is needed and improving the safety during use of the trolley.
[0030] The magnetic field generating structure 2 comprises a top plate 21, opposite sides of the top plate 21 are bent to form two parallel side plates 22, the inner sides of the two side plates 22 are connected with two magnets 23, and a gap for accommodating the brake is arranged between the two magnets 23; the magnetic poles of the side close to each other of the two magnets 23 are two opposite magnetic poles; a transition part 231 is arranged on the magnet 23 and located at one end close to the head of the trolley 1.
[0031] The two magnets 23 can form magnetic fields, and the side close to each other of the two magnets 23 is two opposite magnetic poles, so that the magnetic induction lines from one magnet 23 to the other magnet 23 are distributed between the two magnets 23, and the magnetic induction lines between the parallel sections of the two magnets 23 are parallel to each other. When the trolley 1 moves, the brake enters between the two magnets 23 and cuts the magnetic induction lines, according to Ohm's law, a force hindering the forward movement of the trolley 1 is generated in the process of cutting the magnetic induction lines, thereby slowing down or braking the trolley 1.
[0032] Since the magnetic induction lines are radial, the brake begins to cut the magnetic induction lines when it is in the area between the two magnets 23, and the magnetic field strength is small at this time, so the generated resistance is small; as the brake approaches the magnet 23, the magnetic field strength gradually increases, the generated resistance also gradually increases, and the slowing down effect on the trolley is more obvious; when the brake enters the area between the two magnets 23, the magnetic field strength is the largest at this time, the generated resistance is the largest, and the slowing down effect is more obvious; therefore, the magnetic field generating structure 2 and the brake are used to slow down the trolley 1, the resistance gradually increases from 0, the passengers do not feel obvious slowing down, and a better riding experience is provided for the passengers.
[0033] Further, the inner side of the transition part 231 is provided with an inclined surface, which is formed by extending from the end of the magnet 23 close to the head of the trolley 1 to the direction of the tail of the trolley 1 to the inner side surface of the magnet 23, and gradually approaches the other magnet in the direction from the head to the tail of the trolley 1.
[0034] The transition part 23 can provide a transition area for the increase of the magnetic field strength, make the resistance more linear in the increasing process, and better prompt the riding experience of the rider.
[0035] The first connecting part 31 for rotationally connecting to the trolley 1 is arranged on the mounting rack 3, and a plurality of first transmission teeth 32 are arranged on the side surface of the first connecting part 31; the second connecting part 411 for rotationally connecting to the trolley 1 is arranged on the reset handle 41, and a plurality of second transmission teeth 412 are arranged on the side surface of the second connecting part 411, and the first transmission teeth 32 and the second transmission teeth 412 can be engaged for transmission.
[0036] The first connecting part 31 and the second connecting part 411 are transmitted through the first transmission teeth 32 and the second transmission teeth 412, which ensures that the transmission has sufficient reliability, and the gear transmission has sufficient reaction speed, which can collect the magnetic field generating structure 2 within the first time of deceleration or braking, avoiding affecting the normal operation of the trolley 1.
[0037] The other end of the reset handle 41 away from the end rotationally connected to the trolley 1 is rotationally connected with a first abutting wheel 413, and a touch strip is arranged on the track, which can make the first abutting wheel 413 move relative to the trolley 1, drive the reset handle 41 to rotate, and drive the mounting rack 3 to rotate around the point rotationally connected to the trolley 1 as the center to rotate upward, and collect the magnetic field generating structure 2 to the initial position.
[0038] During the movement of the trolley 1, the reset handle 41 will automatically rotate under the cooperation of the first abutting wheel 413 and the touch strip, drive the mounting rack 3 to rotate, and collect the magnetic field generating structure 2 to the initial position when the trolley 1 moves to the specified position, avoiding affecting the normal operation of the trolley 1, and protecting the magnetic field generating structure 2.
[0039] The first spring 24 is connected to the magnetic field generating structure 2, one end of the first spring 24 is connected to the magnetic field generating structure 2, and the other end is connected to the trolley 1; and when the magnetic field generating structure 2 is working, the end of the first spring 24 connected to the trolley 1 is higher than the end of the first spring 24 connected to the magnetic field generating structure 2.
[0040] Through the first spring 24, the position of the resistance generating structure 2 can be changed when the magnetic field generating structure 2 is in the working state, improving the self-adaptive ability of the magnetic field generating structure 2.
[0041] When the moving speed of the trolley 1 is greater than the preset speed, the magnetic field generating structure 2 will move downward under the action of the resistance due to the large speed and the large resistance generated, thereby increasing the overlapping area of the magnet 23 and the brake, further increasing the generated resistance, and the deceleration effect on the trolley is stronger; when the speed of the trolley 1 decreases or is less than the preset speed, the magnetic field generating structure 2 will move upward under the action of the first spring 24 due to the small speed and the small resistance generated, thereby reducing the overlapping area of the magnet 23 and the brake, further reducing the generated resistance, and the deceleration effect on the trolley is weaker; therefore, the resistance generating structure has the ability of self-adapting to adjust the resistance size through the first spring 24.
[0042] Further, in another embodiment, the mounting rack 3 is further provided with a limiting portion 33, and the limiting portion 33 is provided with a limiting protrusion 331; the trolley 1 is further connected with a limiting assembly 5, and the limiting assembly includes a limiting plate 51 connected to the trolley 1, one end of the limiting plate 51 is rotatably connected to the trolley 1, and the other end is provided with at least one limiting gap 511, and the limiting protrusion 331 can be embedded into the limiting gap 511.
[0043] Through the cooperation of the limiting protrusion 331 and the limiting gap 511, the magnetic field generating structure 2 can be prevented from shaking with the ups and downs of the trolley during the movement of the trolley 1, ensuring that the magnetic field generating structure 2 does not affect the normal operation of the trolley 1, and protecting the magnetic field generating structure 2.
[0044] When it is necessary to switch the position of the magnetic field generating structure 2, it is necessary to disconnect the connection between the limiting protrusion 331 and the limiting gap 511, and the limiting assembly 5 functions as a safety switch to ensure better safety during the operation of the trolley.
[0045] Further, in another embodiment, the limiting assembly 5 further includes a rotating shaft 52 rotatably connected to the trolley 1, and one end of the rotating shaft 52 is provided with a limiting handle 53, the limiting handle 53 can drive the rotating shaft 52 to rotate, and the limiting plate 51 is connected to the rotating shaft 52.
[0046] Through the rotating shaft 52 and the limiting handle 52, the control of the limiting plate 51 is facilitated, and the control difficulty is reduced.
[0047] Further, in another embodiment, the rotating shaft 52 is further connected with a reset plate 54, one end of the reset plate 54 is connected to the rotating shaft 52 and can rotate with the rotation of the rotating shaft 52, and the other end of the reset plate is connected to the trolley 1 through a second spring 55.
[0048] After rotating the limiting handle 52, automatic reset can be realized under the cooperation of the second spring 55 and the reset plate 54, the control mode is optimized, and the operation difficulty is better reduced.
[0049] Further, in another embodiment, the mounting rack 3 is located above the rotating shaft 52, and an anti-collision block 34 connected to the mounting rack 3 is arranged above the rotating shaft 52.
[0050] Through the anti-collision block 34, the mounting rack 3 will not directly collide with the rotating shaft 52 during movement, avoiding rigid collision and damage to the mounting rack 3 and the rotating shaft 52, and prolonging the service life. The material of the anti-collision block 34 can be one or more of rubber, PVC, ABS, nylon, and glass fiber reinforced plastic.
[0051] Further, in another embodiment, the limiting handle 53 is rotatably connected to the second abutting wheel 531 at the other end of the end away from the rotating shaft 52, and a touch strip is arranged on the track, which can make the second abutting wheel 531 move relative to the trolley 1, drive the limiting handle 53 to rotate, and drive the rotating shaft 52 and the limiting plate 51 to rotate, so that the limiting protrusion 331 is separated from the limiting gap 511.
[0052] During the movement of the trolley 1, the limiting handle 53 will automatically rotate under the cooperation of the second abutting wheel 531 and the touch strip when the trolley 1 moves to the designated position, and drive the rotating shaft 52 and the limiting plate 51 to rotate, so that the limiting protrusion 331 is separated from the limiting gap 511, at which time the position of the magnetic field generating structure 2 can be adjusted; after the adjustment is completed, the second abutting wheel 531 loses the abutment of the touch strip, and under the cooperation of the second spring 55 and the reset plate 54, the limiting plate 51 is reset, and the limiting protrusion 331 is embedded in the limiting gap 511, so that the limiting plate 51 limits the magnetic field generating structure 2 again.
