Description

Technical Field

[0001] The present invention belongs to the technical field of trains, and in particular relates to a self-protective trackless outdoor amusement train. Background Art

[0002] With the development of science and the progress of society, modern entertainment facilities are widely used in people's lives. Because they integrate knowledge, interest, and science, they are deeply loved by children and teenagers. They play an active role in enriching people's entertainment lives, exercising people's bodies, and cultivating people's sentiments.

[0003] At present, during the use of existing amusement trains, the following problems still exist: Since the children taking the train are generally young and lack safety awareness, and the existing amusement trains lack protective equipment and have low safety performance, when the train is running, once a child collides with the train and the train is difficult to brake in time, on the one hand, it will cause harm to the child, and in severe cases, it may even endanger the child's life. On the other hand, since the train is impacted, it will also cause damage to the train itself, thereby affecting the service life of the train; Therefore, there are deficiencies and it cannot meet the user's needs. Therefore, it is necessary to further improve.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved to provide a self-protective trackless outdoor amusement train, in order to achieve a more practical value purpose. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a self-protective trackless outdoor amusement train, which is achieved by the following specific technical means:

[0006] A self-protective trackless outdoor amusement train includes a chassis frame. A fixed frame is fixedly installed between the inner walls of the chassis frame. A base is arranged directly above the fixed frame. The upper surface of the base is provided with a locomotive head and a control center, and the locomotive head is located on the right side of the control center. A carriage is provided on the side of the locomotive head away from the control center;

[0007] There are several chassis frames, and the chassis frames are connected to each other through connecting parts;

[0008] A reinforcing frame is fixedly installed between the inner side wall of the chassis frame and the fixed frame. A support spring and a support assembly are arranged between the upper side of the fixed frame and the base. The top of the support spring is fixedly connected to the bottom of the base, and the support assembly is located on the front and back sides of the support spring.

[0009] Further, the support assembly includes a support seat, a support member, a buffer spring, and a bearing block;

[0010] The support base is installed on the upper side of the fixing frame. There is a support member directly above the support base. A buffer spring is connected between the support base and the support member. A bearing block is fixedly installed directly above the support member. The upper side of the bearing block is fixedly connected to the bottom of the base. By the cooperative action among the support base, the support member and the buffer spring, the bumpy feeling of the carriage can be effectively reduced. Through double protection, the impact brought by the road surface can be alleviated, and the vibration generated during bumping can be quickly absorbed, effectively reducing the vibration feeling when the train is moving forward and improving people's riding experience.

[0011] Furthermore, an installation frame is provided at the bottom of the chassis frame. A driving motor is installed on the installation frame. The output end of the driving motor is connected with a rotating shaft, and a traveling wheel is installed on the rotating shaft. Through the effective control of the staff, the amusement train can be driven to run. The output end of the driving motor drives the rotating shaft to rotate, and then the traveling wheel can be synchronously driven to run.

[0012] Furthermore, a damping shock absorber is provided between the bottom of the chassis frame and the installation frame. The damping shock absorber includes a damping sleeve, a damping spring, an installation block and an electrode plate.

[0013] The top of the damping sleeve is fixedly connected to the lower side of the chassis frame. A damping spring is connected between the damping sleeve and the installation frame. There are two installation blocks inside the damping spring. The two installation blocks are respectively installed on the damping sleeve and the installation frame. Electrode plates are provided on the opposite sides of the two installation blocks, and the two electrode plates are electrically connected. Through the setting of the damping spring, the bumpy feeling during the operation of the traveling wheel can be effectively alleviated, and the bumping degree during the train operation can be reduced, playing an effective protective role in the train operation. When the bumpy feeling is strong, it causes the electrode plates on the installation blocks to contact each other, thereby achieving the effect of reducing the rotation speed of the traveling wheel and the traveling speed of the train, and achieving the purpose of self-protection by reducing the vehicle speed.

[0014] Furthermore, a protection plate is provided on the outside of the chassis frame. A protection component and a buffer air cushion are provided between the chassis frame and the protection plate, and both the protection component and the buffer air cushion are installed on the outer side wall of the chassis frame. The buffer air cushion is arranged on the left and right sides of the protection component. The impact force can be effectively buffered by the buffer air cushion, and at the same time, it can also buffer the children who have a collision, reducing the possibility of their injury.

[0015] Furthermore, the protection component includes a protection shell, a protection main rod, a movable connecting rod, a buffer connecting rod and an elastic resetting member.

[0016] The protective housing is installed on the outer wall of the chassis frame. Inside the protective housing, there is a main protective rod. The outer end of the main protective rod is fixedly connected to a protective plate. On the left and right sides of the main protective rod, movable connecting rods are movably installed. One end of the movable connecting rod away from the main protective rod is movably connected to a buffer connecting rod. An elastic resetting member is arranged between the buffer connecting rod and the inner wall of the protective housing. When the protective plate moves, it will drive the main protective rod to move synchronously, enabling the buffer connecting rod to contact the protective plate. The buffer connecting rod impacts the protective plate in the opposite direction, effectively alleviating the collision of external forces on the protective plate and offsetting each other, thus achieving the purpose of autonomously protecting the train.

[0017] Further, an induction component is provided inside the protective housing. The induction component includes a first induction sheet and a second induction sheet.

[0018] The first induction sheet is installed at one end of the main protective rod away from the protective plate. On the side of the first induction sheet away from the main protective rod and on the inner wall of the protective housing, a second induction sheet is installed. The first induction sheet and the second induction sheet are electrically connected. When the protective plate is impacted and drives the main protective rod to move, it will simultaneously drive the first induction sheet to move synchronously, and then the first induction sheet will contact the second induction sheet.

[0019] Further, a signal transmitter is provided on one side of the protective housing close to the chassis frame. The signal transmitter passes through the chassis frame and is located in the fixing frame. The signal transmitter is electrically connected to the first induction sheet and the second induction sheet. When the first induction sheet contacts the second induction sheet, the signal transmitter emits an electrical signal, and the control center takes measures after receiving the electrical signal.

[0020] Further, iron sheets are fixedly installed on the opposite sides of the traveling wheels. On the inner wall of the chassis frame and on the side opposite to the traveling wheels, a driving power source is installed. An electromagnet is provided on the side of the driving power source opposite to the traveling wheels. The electromagnet is in close contact with the iron sheet. The driving power source and the electromagnet are electrically connected. By transmitting electrical energy to the electromagnet through the driving electrical energy, the electromagnet generates a strong magnetic force after being energized. The iron sheet outside the traveling wheel can be firmly adsorbed by the magnetic force, so that the traveling wheel achieves emergency braking and autonomous protection, further improving the safety performance of the train.

[0021] Beneficial effects

[0022] Compared with the prior art, the present invention provides a self-protective trackless outdoor amusement train, which has the following beneficial effects:

[0023] 1. The self-protective trackless outdoor amusement train. Through the cooperation among the protective plate, the protection component, the first induction piece, the second induction piece, the signal transmitter, the iron sheet, the driving power supply and the electromagnet, the device can cut off the power supply of the driving motor, making the walking wheels lose the power source. And the iron sheet outside the walking wheels can be firmly adsorbed by the magnetic force of the electromagnet, so that the walking wheels achieve emergency braking and self-protection. When an emergency occurs during the train operation, the train can be stopped immediately, avoiding harm to children, further improving the safety performance of the train and making it safer and more reliable to use.

[0024] 2. The self-protective trackless outdoor amusement train. Through the cooperation among the support spring, the support seat, the support piece, the buffer spring, the mounting bracket and the damping shock absorber, the double protection can relieve the impact brought by the road surface, quickly absorb the vibration generated during bumping, effectively reduce the vibration feeling when the train is moving forward, improve people's riding feeling, solve the problem of road bumps, and while filtering the vibration feeling generated during bumping, it can also extend the service life of the train, achieving the purpose of effectively protecting the train itself.

[0025] 3. The self-protective trackless outdoor amusement train. When the bumping feeling is strong, through the cooperation among the damping sleeve, the damping spring, the mounting block and the electrode piece, it promotes the electrode pieces on the mounting block to contact each other and emit an electric signal. Then the control center receives the electric signal and sends a signal to control the output speed of the driving motor, so as to achieve the effect of reducing the rotation speed of the walking wheels and the traveling speed of the train, and achieve the purpose of self-protection by reducing the vehicle speed, further improving its use effect.

[0026] 4. The self-protective trackless outdoor amusement train. Through the cooperation among the protective plate, the protective housing, the main protective rod, the movable connecting rod, the buffer connecting rod, the elastic reset piece and the buffer air cushion, it can buffer the children who have a collision, reduce the possibility of their injury, and at the same time use the buffer connecting rod to impact the protective plate in the reverse direction, so as to effectively relieve the collision of the external force on the protective plate and make them cancel each other out, thus achieving the purpose of self-protection for the train.

[0046] The support assembly 10 includes a support seat 101, a support member 102, a buffer spring 103, and a bearing block 104;

[0047] The support seat 101 is installed on the upper side of the fixed frame 2. A support member 102 is provided directly above the support seat 101. A buffer spring 103 is provided between the support seat 101 and the support member 102. A bearing block 104 is fixedly installed directly above the support member 102, and the upper side of the bearing block 104 is fixedly connected to the bottom of the base 3; By the cooperation of the support seat 101, the support member 102, and the buffer spring 103, the bumpy feeling of the carriage 6 can be effectively reduced. Through double protection, the impact brought by the road surface can be alleviated, and the vibration generated during bumping can be quickly absorbed, which can effectively reduce the vibration feeling when the train is moving and improve people's riding experience.

[0048] At the bottom of the chassis frame 1, a mounting bracket 11 is provided. A driving motor 12 is mounted on the mounting bracket 11. A rotating shaft 121 is connected to the output end of the driving motor 12. A traveling wheel 13 is mounted on the rotating shaft 121. Through the effective control of the staff, the amusement train can be driven to run. By driving the rotating shaft 121 to rotate with the output end of the driving motor 12, the traveling wheel 13 can be synchronously driven to run.

[0049] Between the bottom of the chassis frame 1 and the mounting bracket 11, a damping shock absorber 14 is provided. The damping shock absorber 14 includes a damping sleeve 141, a damping spring 142, a mounting block 143 and an electrode plate 144.

[0050] The top of the damping sleeve 141 is fixedly connected to the lower side of the chassis frame 1. A damping spring 142 is connected between the damping sleeve 141 and the mounting bracket 11. Two mounting blocks 143 are provided inside the damping spring 142. The two mounting blocks 143 are respectively mounted on the damping sleeve 141 and the mounting bracket 11. Electrode plates 144 are provided on the opposite sides of the two mounting blocks 143. The two electrode plates 144 are electrically connected. Through the setting of the damping spring 142, the bumpiness during the operation of the traveling wheel 13 can be effectively alleviated, the bumpiness degree during the train operation can be reduced, and an effective protection effect on the train operation can be achieved. When the bumpiness is strong, the electrode plates 144 on the mounting blocks 143 are urged to contact each other, so as to achieve the effect of reducing the rotation speed of the traveling wheel 13 and the traveling speed of the train, and the purpose of self-protection is achieved by reducing the vehicle speed.

[0051] A protective plate 15 is provided on the outside of the chassis frame 1. A protective component 16 and a buffer air cushion 17 are provided between the chassis frame 1 and the protective plate 15. Both the protective component 16 and the buffer air cushion 17 are mounted on the outer side wall of the chassis frame 1. The buffer air cushion 17 is arranged on the left and right sides of the protective component 16. Through the buffer air cushion 17, the impact force can be effectively buffered, and at the same time, it can also buffer the children who have a collision, reducing the possibility of their injury.

[0052] The protective component 16 includes a protective shell 161, a protective main rod 162, a movable connecting rod 163, a buffer connecting rod 164 and an elastic reset member 165.

[0053] The protective housing 161 is installed on the outer wall of the chassis frame 1. Inside the protective housing 161, there is a main protective rod 162. The outer end of the main protective rod 162 is fixedly connected to the protective plate 15. On the left and right sides of the main protective rod 162, movable connecting rods 163 are movably installed. One end of the movable connecting rod 163 away from the main protective rod 162 is movably connected to a buffer connecting rod 164. An elastic reset member 165 is connected between the buffer connecting rod 164 and the inner wall of the protective housing 161. When the protective plate 15 moves, it will drive the main protective rod 162 to move synchronously, enabling the buffer connecting rod 164 to contact the protective plate 15. The buffer connecting rod 164 impacts the protective plate 15 in the opposite direction, effectively alleviating the collision of external forces on the protective plate 15 and offsetting each other, thereby achieving the purpose of autonomous protection for the train.

[0054] Inside the protective housing 161, there is an induction component 18, and the induction component 18 includes a first induction sheet 181 and a second induction sheet 182.

[0055] The first induction sheet 181 is installed at one end of the main protective rod 162 away from the protective plate 15. On the side of the first induction sheet 181 away from the main protective rod 162 and on the inner wall of the protective housing 161, a second induction sheet 182 is installed. The first induction sheet 181 and the second induction sheet 182 are electrically connected. When the protective plate 15 is impacted and drives the main protective rod 162 to move, it will drive the first induction sheet 181 to move synchronously, and then the first induction sheet 181 will contact the second induction sheet 182.

[0056] On one side of the protective housing 161 close to the chassis frame 1, there is a signal transmitter 19. The signal transmitter 19 passes through the chassis frame 1 and is located in the fixing frame 2. The signal transmitter 19 is electrically connected to the first induction sheet 181 and the second induction sheet 182. When the first induction sheet 181 contacts the second induction sheet 182, the signal transmitter 19 will emit an electrical signal, and the control center 5 will receive the electrical signal and take measures simultaneously.

[0057] On the opposite sides of the running wheels 13, iron sheets 20 are fixedly installed. On the inner side wall of the chassis frame 1 and on the side opposite to the running wheels 13, a driving power source 21 is installed. On the side of the driving power source 21 opposite to the running wheels 13, there is an electromagnet 22. The electromagnet 22 is in close contact with the iron sheet 20. The driving power source 21 is electrically connected to the electromagnet 22. By transmitting electrical energy to the electromagnet 22 through the driving electrical energy, the electromagnet 22 generates a strong magnetic field after being energized. Using the magnetic force, the iron sheet 20 outside the running wheels 13 can be firmly adsorbed, thereby enabling the running wheels 13 to achieve emergency braking and autonomous protection, further improving the safety performance of the train.

[0058] The specific usage method and function of this embodiment:

[0059] Working principle: Currently, with the development of science and the progress of society, modern entertainment facilities are widely used in people's lives, and amusement trains are deeply loved by children and teenagers, effectively enriching people's entertainment life. Through the effective operation of the staff, the amusement train can be driven to run. Children can enjoy the fun brought by the amusement train while sitting in the carriage 6. During the running process of the amusement train, due to uncontrollable factors in the external environment, there is a possibility of road bumps. When the running wheels 13 run on the bumpy road surface, at this time, the bumpy feeling will be transmitted to the driving motor 12 and the mounting frame 11 through the running wheels 13. Through the setting of the damping spring 142, the bumpy feeling during the operation of the running wheels 13 can be effectively alleviated, the bumpy degree during the running of the train can be reduced, and an effective protective effect on the running of the train can be achieved. At the same time, through the setting of the support spring 9 and the support assembly 10, by the cooperation between the support seat 101, the support member 102 and the buffer spring 103, the bumpy feeling of the carriage 6 can be effectively reduced. Through double protection, the impact brought by the road surface can be alleviated, the vibration generated during bumps can be quickly absorbed, the vibration feeling during the train's progress can be effectively reduced, the riding feeling of people can be improved, and while filtering the vibration feeling generated during bumps, the service life of the train can also be increased, effectively protecting the train itself;

[0060] And when the bumpy feeling is strong, as the running wheels 13 drive the mounting frame 11 to continuously vibrate up and down, the damping spring 142 is repeatedly compressed, and at the same time, the electrode plates 144 on the mounting block 143 are urged to contact each other, thereby emitting an electrical signal. Then, the control center 5 receives the electrical signal and issues a signal to control the output rate of the driving motor 12, so as to achieve the effect of reducing the rotation rate of the running wheels 13 and the running speed of the train, and achieve the purpose of self-protection by reducing the vehicle speed, further improving its use effect;

[0061] In addition, since the children taking the train are generally young and lack safety awareness, and during the operation of the amusement train, once a child collides with the train or the train collides with a child, at this time, the setting of the protection plate 15 enables the protection plate 15 to come into contact with the child first. Based on the collision force during the impact, the protection plate 15 can move towards the chassis frame 1. The impact force can be effectively buffered by the buffer air cushion 17, and at the same time, it can also buffer the child involved in the collision, reducing the possibility of their injury. When the protection plate 15 moves, it will drive the main protection rod 162 to move synchronously, causing the main protection rod 162 to move towards the inside of the protection housing 161. Through the setting of the movable connecting rod 163, the buffer connecting rod 164 can move in the opposite direction to the main protection rod 162, while pulling the elastic reset member 165, and making the buffer connecting rod 164 come into contact with the protection plate 15. The buffer connecting rod 164 impacts the protection plate 15 in the reverse direction, so as to effectively relieve the collision of the external force on the protection plate 15 and make them cancel each other out, thus achieving the purpose of autonomous protection for the train;

[0062] Moreover, when the protection plate 15 is impacted and drives the main protection rod 162 to move, it will simultaneously drive the first sensing piece 181 to move synchronously, so that the first sensing piece 181 will come into contact with the second sensing piece 182, enabling the signal transmitter 19 to emit an electrical signal. When the control center 5 receives the electrical signal, it will take measures to cut off the power supply of the drive motor 12, causing the running wheels 13 to lose the power source, and quickly transfer the driving electrical energy to the electromagnet 22. After the electromagnet 22 is energized, it generates a strong magnetic force, and the iron sheet 20 outside the running wheel 13 can be firmly adsorbed by the magnetic force, so that the running wheels 13 achieve emergency braking and autonomous protection, further improving the safety performance of the train and making it safer and more reliable to use.
